The crankshaft rear oil seal is a press fit in the rear oil
seal retainer. The rear oil seal retainer also houses the
CKP sensor.
CKP sensor trigger wheel1
The trigger wheel is located on the rear of the crankshaft.
It is pressed onto the crankshaft using a special tool,
which also precisely aligns the trigger wheel for
crankshaft position and timing. The trigger wheel
consists of 60 magnets, minus 2 for ECM crankshaft
position reference and...

Main Bearings
The main bearings are aluminium/tin split plain selective
bearings. An oil groove in the top half of each bearing
transfers oil into the crankshaft for lubrication of the
connecting rod bearings. The upper and lower shells of
bearing number four contain integral thrust washers,
which limits the end float of the crankshaft.
Ladder Frame
Ladder frame1
The ladder frame is fitted to the lower cylinder block
to stiffen the base structure thus helping to reduce Noise,
Vibration and Harshness...

An oil pick-up pipe with integral strainer locates in the
front of the ladder frame to provide oil to the crankshaft
driven oil pump.
Sump
The sump consists of a pressed steel oil pan bolted to
the aluminium alloy ladder frame with 14 M6 x 16 bolts.
The engine oil drain plug and the oil temperature sensor
are located at the rear left corner of the sump.
A reusable gasket seals the joint between the oil pan
and the ladder frame; a bead of sealant seals the joint
between the sump and the ladder frame.

Tensioner firing pin5
Secondary drive is provided by two short crossover
chains, which transfer drive from the exhaust camshaft
gears to the inlet camshaft gears. The crossover drives
are located at the rear of the RH cylinder bank and the
front of the LH cylinder bank. This allows for a much
shorter and simpler run for the main camshaft drive belt
at the front of the engine.
Each crossover chain is tensioned via an automatic chain...
