    							and right-hand mountings. Do not yet
    release the hoist; the weight of the
    engine/transmission unit must not be
    taken by the mountings until all are
    correctly aligned.
    (d) Fitting the Ford service tool in place of the
    front mounting, tighten the
    engine/transmission mounting fasteners
    to their specified torque wrench settings,
    and in the sequence described in Part B
    of this Chapter, Section 4, paragraphs 49
    and 50.
    (e) Refill the cooling system (see Chapter 1).
    (f) Refill the engine with oil, remembering
    that you are advised to fit a new filter (see
    Chapter 1).
    (g) Check for signs of oil or coolant leaks
    once the engine has been restarted and
    warmed-up to normal operating
    temperature.
    Removal
    Note:While this task is theoretically possible
    when the engine is in place in the vehicle, in
    practice, it requires so much preliminary
    dismantling, and is so difficult to carry out due
    to the restricted access, that owners are
    advised to remove the engine from the vehicle
    first. Note, however, that the oil pumppressure relief valve can be removed with the
    engine in situ - see paragraph 8.
    In addition to the new pump gasket and
    other replacement parts required, read
    through Section 15, and ensure that the
    necessary tools and facilities are available.
    1Remove the timing belt (see Section 10).
    2Withdraw the crankshaft toothed pulley
    and the thrustwasher behind it, noting which
    way round the thrustwasher is fitted (see
    Section 11).
    3Remove the sump (see Section 15).
    4Undo the screws securing the oil pump
    pick-up/strainer pipe to the pump, then
    unscrew the nut and withdraw the oil pump
    pick-up/strainer pipe. Discard the gasket.
    5Unbolt the pump from the cylinder
    block/crankcase (see illustration). Withdraw
    and discard the gasket, and remove the
    crankshaft right-hand oil seal. Thoroughly
    clean and degrease all components,
    particularly the mating surfaces of the pump,
    the sump, and the cylinder block/crankcase.
    Inspection
    6Unscrew the Torx screws, and remove the
    pump cover plate; noting any identification
    marks on the rotors, withdraw the rotors (see
    illustration).
    7Inspect the rotors for obvious signs of wear
    or damage, and renew if necessary; if either
    rotor, the pump body, or its cover plate are
    scored or damaged, the complete oil pump
    assembly must be renewed.
    8The oil pressure relief valve can bedismantled, if required, without disturbing the
    pump. With the vehicle parked on firm level
    ground, apply the handbrake securely and
    raise its front end, supporting it securely on
    axle stands. Remove the front right-hand
    roadwheel and auxiliary drivebelt cover (see
    Chapter 1) to provide access to the valve.
    9Unscrew the threaded plug, and recover
    the valve spring and plunger (see
    illustrations). If the plug’s sealing O-ring is
    worn or damaged, a new one must be
    obtained, to be fitted on reassembly.
    10Reassembly is the reverse of the
    dismantling procedure; ensure the spring and
    valve are refitted the correct way round, and
    tighten the threaded plug securely.
    Refitting
    11The oil pump must be primed on
    installation, by pouring clean engine oil into it,
    and rotating its inner rotor a few turns.
    12Using grease to stick the new gasket in
    place on the cylinder block/crankcase, and
    rotating the pump’s inner rotor to align with
    the flats on the crankshaft, refit the pump and
    insert the bolts, tightening them lightly at first
    (see illustration).
    13Using a suitable straight edge and feeler
    gauges, check that the pump is both centred
    exactlyaround the crankshaft, and aligned
    squarely so that its (sump) mating surface is
    exactly the same amount - between 0.3 and
    0.8 mm - below that of the cylinder block/
    crankcase on each side of the crankshaft
    (see illustration). Being careful not to disturb

    14Check that the pump is correctly located;
    if necessary, unbolt it again, and repeat the
    full procedure to ensure that the pump is
    correctly aligned.
    15Fit a new crankshaft right-hand oil seal
    (see Section 20).
    16Using grease to stick the gasket in place
    on the pump, refit the pick-up/strainer pipe,
    tightening its screws and nut to their specified
    torque wrench settings (see illustration).
    17The remainder of reassembly is the
    reverse of the removal procedure, referring to
    the relevant text for details where required.
    1Drain the cooling system (see Chapter 1).
    Disconnect the coolant hoses from the oil
    cooler.
    2Unscrew the oil filter (see Chapter 1) -
    catch any escaping oil in a drip tray.
    3Unscrew the filter adaptor from the oil
    pump, and withdraw the oil cooler; note how
    its unions are aligned, and be prepared for oil
    loss from the cooler.
    4Refitting is the reverse of the removal
    procedure, noting the following points:(a) Renew all O-rings and seals disturbed on
    removal.
    (b) Align the cooler’s unions as noted on
    removal, and tighten the adaptor to the
    specified torque wrench setting.
    (c) Refill the cooling system (see Chapter 1).
    (d) Refit the oil filter, then check the engine
    oil level, and top-up as necessary (see
    Chapter 1).
    (e) Check for signs of oil or coolant leaks once
    the engine has been restarted and warmed-
    up to normal operating temperature.
    1With the vehicle parked on firm level
    ground, open the bonnet and disconnect the
    battery negative (earth) lead - see Chapter 5,
    Section 1.
    2Raise the front of the vehicle, and support it
    securely on axle stands.
    3Undo the two screws, and remove the
    sensor’s cover from the front of the sump
    (see illustration).
    4Unplug the wiring from the sensor (see
    illustration). Where necessary, unplug the
    electrical connector to disconnect the sensor
    wiring, and unclip the connector to release
    the wiring from the vehicle.
    5Unscrew the sensor, and quickly plug the
    sump aperture to minimise oil loss; note the
    sensor’s seal.6Refitting is the reverse of the removal
    procedure; renew the sensor’s seal if it is
    worn or damaged, and tighten the sensor to
    the specified torque wrench setting. Check
    the engine oil level, and top-up as necessary
    (see Chapter 1) - check for signs of oil leaks
    once the engine has been restarted and
    warmed-up to normal operating temperature.
    1The switch is screwed into the rear of the
    cylinder block, above the right-hand
    driveshaft’s support bearing (see
    illustration).
    2With the vehicle parked on firm level
    ground, open the bonnet and disconnect the
    battery negative (earth) lead - see Chapter 5,
    Section 1.
    3Raise the front of the vehicle, and support it
    securely on axle stands.
    4Unplug the wiring from the switch, and
    unscrew it; be prepared for some oil loss.
    5Refitting is the reverse of the removal
    procedure; apply a thin smear of suitable
    sealant to the switch threads, and tighten it to
    the specified torque wrench setting. Check
    the engine oil level, and top-up as necessary
    (see Chapter 1). Check for signs of oil leaks
    once the engine has been restarted and
    warmed-up to normal operating temperature.
    Note:Don’t try to prise these seals out
    without removing the oil pump or seal carrier -
    the seals are too soft, and the amount of
    space available is too small, for this to be
    possible without considerable risk of damage
    to the seal housing and/or the crankshaft
    journal. Follow exactly the procedure given
    below.
    Right-hand seal
    1Remove the oil pump (see Section 16).
    2Drive the oil seal out of the pump from
    behind (see illustration).

    							3Clean the seal housing and crankshaft,
    polishing off any burrs or raised edges, which
    may have caused the seal to fail in the first
    place.
    4Refit the oil pump (see Section 16). Grease
    the lips and periphery of the new seal, to ease
    installation.
    5To fit a new seal, Ford recommend the use
    of their service tool 21-093A, with the
    crankshaft pulley bolt, to draw the seal into
    place; an alternative can be arranged using a
    socket of suitable size, with a washer to
    match the crankshaft pulley bolt (see
    illustration).
    6If such tools are not available, press the
    seal squarely into place by hand; tap it in until
    it is flush with the pump housing, using a soft-
    faced mallet and a socket with an outside
    diameter only slightly smaller than the seal’s
    (see illustration). This approach requires
    great care, to ensure that the seal is fitted
    squarely, without distortion or damage.
    7Wash off any traces of oil. The remainder of
    reassembly is the reverse of the removal
    procedure, referring to the relevant text for
    details where required. Check for signs of oil
    leakage when the engine is restarted.
    Left-hand seal
    8Remove the transmission (see the relevant
    Part of Chapter 7).
    9Where appropriate, remove the clutch
    (Chapter 8).
    10Unbolt the flywheel/driveplate (see
    Section 21).11Remove the sump (see Section 15).
    12Unbolt the oil seal carrier (see
    illustration). Remove and discard its gasket.
    13Supporting the carrier evenly on wooden
    blocks, drive the oil seal out of the carrier
    from behind (see illustration).
    14Clean the seal housing and crankshaft,
    polishing off any burrs or raised edges, which
    may have caused the seal to fail in the first
    place. Clean also the mating surfaces of the
    cylinder block/crankcase and carrier, using a
    scraper to remove all traces of the old gasket
    - be careful not to scratch or damage the
    material of either - then use a suitable solvent
    to degrease them.
    15Use grease to stick the new gasket in
    place on the cylinder block/crankcase, then
    offer up the carrier (see illustration).
    16Using a suitable straight edge and feeler
    gauges, check that the carrier is both centred
    exactlyaround the crankshaft, and aligned
    squarely so that its (sump) mating surface is
    exactly the same amount - between 0.3 and
    0.8 mm - below that of the cylinder
    block/crankcase on each side of the
    crankshaft. Being careful not to disturb the
    gasket, move the carrier into the correct
    position, and tighten its bolts to the specified
    torque wrench setting (see illustration).
    17Check that the carrier is correctly located;
    if necessary, unbolt it again, and repeat the
    full procedure to ensure that the carrier is
    correctly aligned.
    18Ford’s recommended method of seal
    fitting is to use service tool 21-141, with twoflywheel bolts to draw the seal into place. If
    this is not available, make up a guide from a
    thin sheet of plastic or similar, lubricate the
    lips of the new seal and the crankshaft
    shoulder with grease, then offer up the seal,
    with the guide feeding the seal’s lips over the
    crankshaft shoulder (see illustration). Press
    the seal evenly into its housing by hand only,
    and use a soft-faced mallet gently to tap it
    into place until it is flush with the surrounding
    housing.
    19Wipe off any surplus oil or grease; the
    remainder of the reassembly procedure is the
    reverse of dismantling, referring to the
    relevant text for details where required.
    Check for signs of oil leakage when the
    engine is restarted.

    							Removal
    1Remove the transmission (see the relevant
    Part of Chapter 7). Now is a good time to
    check components such as oil seals and
    renew them if necessary.
    2Where appropriate, remove the clutch
    (Chapter 8). Now is a good time to check or
    renew the clutch components and pilot
    bearing.
    3Use a centre-punch or paint to make
    alignment marks on the flywheel/driveplate
    and crankshaft, to ensure correct alignment
    during refitting.
    4Prevent the flywheel/driveplate from
    turning by locking the ring gear teeth, or by
    bolting a strap between the flywheel/
    driveplate and the cylinder block/
    crankcase. Slacken the bolts evenly until all
    are free.
    5Remove each bolt in turn, and ensure that
    new replacements are obtained for
    reassembly; these bolts are subjected to
    severe stresses, and so must be renewed,
    regardless of their apparent condition,
    whenever they are disturbed.
    6Noting the reinforcing plate (automatic
    transmission-equipped models only),
    withdraw the flywheel/driveplate; do not drop
    it - it is very heavy.
    Inspection
    7Clean the flywheel/driveplate to remove
    grease and oil. Inspect the surface for cracks,
    rivet grooves, burned areas and score marks.
    Light scoring can be removed with emery
    cloth. Check for cracked and broken ring gear
    teeth. Lay the flywheel/driveplate on a flat
    surface, and use a straight edge to check for
    warpage.
    8Clean and inspect the mating surfaces of
    the flywheel/driveplate and the crankshaft. If
    the crankshaft left-hand seal is leaking, renew
    it (see Section 20) before refitting the
    flywheel/driveplate.
    9While the flywheel/driveplate is removed,clean carefully its inboard (right-hand) face,
    particularly the recesses which serve as the
    reference points for the crankshaft
    speed/position sensor. Clean the sensor’s tip,
    and check that the sensor is securely
    fastened.
    Refitting
    10On refitting, ensure that the
    engine/transmission adaptor plate is in place
    (where necessary), then fit the
    flywheel/driveplate to the crankshaft so that
    all bolt holes align - it will fit only one way -
    check this using the marks made on removal.
    Do not forget the reinforcing plate (where
    fitted).
    11Lock the flywheel/driveplate by the
    method used on dismantling. Working in a
    diagonal sequence to tighten them evenly,
    and increasing to the final amount in two or
    three stages, tighten the new bolts to the
    specified torque wrench setting (see
    illustration).
    12The remainder of reassembly is the
    reverse of the removal procedure, referring to
    the relevant text for details where required.
    General
    1The engine/transmission mountings
    seldom require attention, but broken or
    deteriorated mountings should be renewed
    immediately, or the added strain placed on
    the driveline components may cause damage
    or wear.
    2While separate mountings may be removed
    and refitted individually, if more than one is
    disturbed at a time - such as if theengine/transmission unit is removed from its
    mountings - they must be reassembled and
    their fasteners tightened in a strict sequence.
    3On reassembly, the weight of the
    engine/transmission unit must not be taken
    by the mountings until all are correctly
    aligned. Fitting the Ford service tool in place
    of the front mounting, tighten the
    engine/transmission mounting fasteners to
    their specified torque wrench settings, and in
    the sequence described in Part B of this
    Chapter, Section 4, paragraphs 49 and 50.
    Inspection
    4During the check, the engine/transmission
    unit must be raised slightly, to remove its
    weight from the mountings.
    5Raise the front of the vehicle, and support it
    securely on axle stands. Position a jack under
    the sump, with a large block of wood
    between the jack head and the sump, then
    carefully raise the engine/transmission just
    enough to take the weight off the mountings. 
    Warning: DO NOT place any part
    of your body under the engine
    when it is supported only by a
    jack!
    6Check the mountings to see if the rubber is
    cracked, hardened or separated from the
    metal components. Sometimes the rubber
    will split right down the centre.
    7Check for relative movement between each
    mounting’s brackets and the engine/
    transmission or body (use a large screwdriver
    or lever to attempt to move the mountings). If
    movement is noted, lower the engine and
    check-tighten the mounting fasteners.

    subframe, unscrew the centre bolt and
    withdraw the mounting; note the location of
    the wiring connector bracket. The mounting’s
    bracket can be unbolted from the
    transmission if required (see illustration).
    9On refitting, ensure that the mounting-to-
    transmission bolts are securely tightened,
    then refit the mounting and wiring connector
    bracket. Tighten first the mounting-to-
    subframe bolts/nuts, noting that these are to
    be tightened in two stages to the final
    specified torque wrench setting. Finally
    tighten the mounting’s centre bolt, again to
    the specified torque wrench setting.
    Right-hand mounting
    10Unscrew the nuts and withdraw the
    bracket; note that these nuts are self-locking,
    and must therefore be renewed wheneverthey are disturbed. Unbolt the mounting from
    the body (see illustration).
    11Where hydraulic-type mountings are
    fitted - there are only five nuts securing the
    bracket, and the mounting is clearly
    identifiable from its shape - take care never to
    tilt these more than 5° from the vertical (see
    illustration).
    12On refitting, renew the self-locking nuts,
    and tighten all fasteners to the torque wrench
    settings specified. When tightening the nuts,
    tighten first the four bracket-to-engine nuts,
    then release the hoist or jack to allow the
    engine/transmission’s weight to rest on the
    mounting. Do not allow the mounting to twist
    as the last two of the nuts are tightened (see
    illustration).
    Left-hand mounting
    13Unplugging the two electrical connectors,
    disconnecting the vacuum hose (where fitted)
    and disconnecting the crankcase breather
    hose from the cylinder head cover, remove
    the complete air cleaner assembly with the air
    mass meter, the resonator and the plenum
    chamber (see Chapter 4).
    14Unscrew the three nuts to release the
    mounting from the transmission, then unbolt

    2B•2 Engine removal and general engine overhaul procedures 
    						
    							How to use this Chapter
    This Part of Chapter 2 is devoted to
    engine/transmission removal and refitting, to
    those repair procedures requiring the removal
    of the engine/transmission from the vehicle,
    and to the overhaul of engine components. It
    includes only the Specifications relevant to
    those procedures. Refer to Part A for
    additional Specifications, if required.
    General information
    The information ranges from advice
    concerning preparation for an overhaul and
    the purchase of replacement parts, to detailed
    step-by-step procedures covering removal
    and installation of internal engine components
    and the inspection of parts.
    The following Sections have been written
    based on the assumption that the engine has
    been removed from the vehicle. For
    information concerning in-vehicle engine
    repair, as well as removal and installation of
    the external components necessary for the
    overhaul, see Part A of this Chapter and
    Section 5 of this Part.
    When overhauling this engine, it is essential
    to establish first exactly what replacement
    parts are available. At the time of writing,
    components such as the piston rings are not
    available separately from the
    piston/connecting rod assemblies; pistons,
    gudgeon pins and valve guides are not
    available separately, and very few under- or
    oversized components are available for
    engine reconditioning. In most cases, it would
    appear that the easiest and most
    economically-sensible course of action is to
    replace a worn or damaged engine with an
    exchange unit.
    It’s not always easy to determine when, or
    if, an engine should be completely
    overhauled, as a number of factors must be
    considered.
    High mileage is not necessarily an
    indication that an overhaul is needed, while
    low mileage doesn’t preclude the need for an
    overhaul. Frequency of servicing is probably
    the most important consideration. An engine
    that’s had regular and frequent oil and filter
    changes, as well as other required
    maintenance, will most likely give many
    thousands of miles of reliable service.
    Conversely, a neglected engine may require
    an overhaul very early in its life.
    Excessive oil consumption is an indication
    that piston rings, valve seals and/or valve
    guides are in need of attention. Make surethat oil leaks aren’t responsible before
    deciding that the rings and/or guides are
    worn. Perform a cylinder compression check
    (Part A of this Chapter, Section 3) to
    determine the extent of the work required.
    Loss of power, rough running, knocking or
    metallic engine noises, excessive valve train
    noise and high fuel consumption rates may
    also point to the need for an overhaul,
    especially if they’re all present at the same
    time. If a full service doesn’t remedy the
    situation, major mechanical work is the only
    solution.
    An engine overhaul involves restoring all
    internal parts to the specification of a new
    engine. Note:Always check first what
    replacement parts are available before
    planning any overhaul operation; refer to
    Section 1 of this Part. Ford dealers, or a good
    engine reconditioning specialist/automotive
    parts supplier may be able to suggest
    alternatives which will enable you to overcome
    the lack of replacement parts.
    During an overhaul, it is usual to renew the
    piston rings, and to rebore and/or hone the
    cylinder bores; where the rebore is done by an
    automotive machine shop, new oversize
    pistons and rings will also be installed - all
    these operations, of course, assume the
    availability of suitable replacement parts. The
    main and big-end bearings are generally
    renewed and, if necessary, the crankshaft
    may be reground to restore the journals.
    Generally, the valves are serviced as well,
    since they’re usually in less-than-perfect
    condition at this point. While the engine is
    being overhauled, other components, such as
    the starter and alternator, can be renewed as
    well, or rebuilt, if the necessary parts can be
    found. The end result should be an as-new
    engine that will give many trouble-free miles.
    Note:Critical cooling system components
    such as the hoses, drivebelt, thermostat and
    water pump MUST be replaced with new
    parts when an engine is overhauled. The
    radiator should be checked carefully, to
    ensure that it isn’t clogged or leaking (see
    Chapter 3). Also, as a general rule, the oil
    pump should be renewed when an engine is
    rebuilt.
    Before beginning the engine overhaul, read
    through the entire procedure to familiarise
    yourself with the scope and requirements of
    the job. Overhauling an engine isn’t difficult,
    but it is time-consuming. Plan on the vehicle
    being off the road for a minimum of two
    weeks, especially if parts must be taken to an
    automotive machine shop for repair or
    reconditioning. Check on availability of parts,
    and make sure that any necessary special
    tools and equipment are obtained in advance.
    Most work can be done with typical hand
    tools, although a number of precision
    measuring tools are required, for inspecting
    parts to determine if they must be replaced.
    Often, an automotive machine shop will
    handle the inspection of parts, and will offer
    advice concerning reconditioning andreplacement. Note:Always wait until the
    engine has been completely dismantled, and
    all components, especially the cylinder
    block/crankcase, have been inspected, before
    deciding what service and repair operations
    must be performed by an automotive machine
    shop. Since the block’s condition will be the
    major factor to consider when determining
    whether to overhaul the original engine or buy
    a rebuilt one, never purchase parts or have
    machine work done on other components
    until the cylinder block/crankcase has been
    thoroughly inspected.As a general rule, time
    is the primary cost of an overhaul, so it
    doesn’t pay to install worn or sub-standard
    parts.
    As a final note, to ensure maximum life and
    minimum trouble from a rebuilt engine,
    everything must be assembled with care, in a
    spotlessly-clean environment.
    If you’ve decided that an engine must be
    removed for overhaul or major repair work,
    several preliminary steps should be taken.
    Locating a suitable place to work is
    extremely important. Adequate work space,
    along with storage space for the vehicle, will
    be needed. If a workshop or garage isn’t
    available, at the very least, a flat, level, clean
    work surface made of concrete or asphalt is
    required.
    Cleaning the engine compartment and
    engine/transmission before beginning the
    removal procedure will help keep tools clean
    and organized.
    The engine can only be withdrawn by
    removing it complete with the transmission;
    the vehicle’s body must be raised and
    supported securely, sufficiently high that the
    engine/transmission can be unbolted as a
    single unit and lowered to the ground; the
    engine/transmission unit can then be
    withdrawn from under the vehicle and
    separated. An engine hoist or A-frame will
    therefore be necessary. Make sure the
    equipment is rated in excess of the combined
    weight of the engine and transmission. Safety
    is of primary importance, considering the
    potential hazards involved in removing the
    engine/transmission from the vehicle.
    If this is the first time you have removed an
    engine, a helper should ideally be available.
    Advice and aid from someone more
    experienced would also be helpful. There are
    many instances when one person cannot
    simultaneously perform all of the operations
    required when removing the engine/
    transmission from the vehicle.
    Plan the operation ahead of time. Arrange for,
    or obtain, all of the tools and equipment you’ll
    need prior to beginning the job. Some of the
    equipment necessary to perform
    engine/transmission removal and installation

    							safely and with relative ease, and which may
    have to be hired or borrowed, includes (in
    addition to the engine hoist) a heavy-duty trolley
    jack, a strong pair of axle stands, some wooden
    blocks, and an engine dolly (a low, wheeled
    platform capable of taking the weight of the
    engine/transmission, so that it can be moved
    easily when on the ground). A complete set of
    spanners and sockets (as described in the front
    of this manual) will obviously be needed,
    together with plenty of rags and cleaning
    solvent for mopping-up spilled oil, coolant and
    fuel. If the hoist is to be hired, make sure that
    you arrange for it in advance, and perform all of
    the operations possible without it beforehand.
    This will save you money and time.
    Plan for the vehicle to be out of use for
    quite a while. A machine shop will be required
    to perform some of the work which the do-it-
    yourselfer can’t accomplish without special
    equipment. These establishments often have
    a busy schedule, so it would be a good idea
    to consult them before removing the engine,
    to accurately estimate the amount of time
    required to rebuild or repair components that
    may need work.
    Always be extremely careful when removing
    and installing the engine/transmission.
    Serious injury can result from careless
    actions. By planning ahead and taking your
    time, the job (although a major task) can be
    accomplished successfully.
    Warning: Petrol is extremely
    flammable, so take extra
    precautions when disconnecting
    any part of the fuel system. Don’t
    smoke, or allow naked flames or bare light
    bulbs in or near the work area, and don’t
    work in a garage where a natural gas
    appliance (such as a clothes dryer or water
    heater) is installed. If you spill petrol on
    your skin, rinse it off immediately. Have a
    fire extinguisher rated for petrol fires
    handy, and know how to use it.Note: Read through the entire Section, as well
    as reading the advice in the preceding Section,
    before beginning this procedure. The engine
    and transmission are removed as a unit,
    lowered to the ground and removed from
    underneath, then separated outside the vehicle.
