6.3 REPLACEMENT OF THE STEERING 
COMPONENTS

Remove the wheel cover [see 5.1].

Position the machine vertically [see 2.4].
NOTE
The vertical position allows greater visibility of the
steering components.
Unhook the spring 
(1)which holds the pinion (2)
and lift the column (3)in order to pull out the pin (4)
and remove the pinion (2).
Take out the split pin 
(5)that fastens the tie-rod (6)
to the pin (7) and unscrew the locknut (8)and the
nut 
(9)securing the entire ring gear shaft (10)to the
frame.
At this point, each component can be dismantled
for any necessary checks or replacements.
On assembly, check that with the front wheels
aligned, the position of the pin
(7)is exactly in line
with the longitudinal axis of the machine and that
the pinion
(2)is positioned with the pin (4)fitted at
90° to the machine axle.
Check that the anti-friction washers
(11), (12)and
(13) are positioned correctly. When refitting the ring
gear shaft 
(10), tighten the nut (9)to ensure a good
rotation without too much play, then fully tighten the
locknut 
(8).

Remount the wheel cover [see 5.1].
When assembly is complete, ...

Check the steering geometry [see 4.5.B].

6.4 REPLACEMENT OF THE BLADE
ENGAGEMENT CLUTCH
NOTE
The clutch has a dual function of engaging the
blade and stopping it at the moment of disengage-
ment.
In the case of any fault deriving from the deteriora-
tion or wear of the friction surface, replace the outer
clutch element.

Position the machine vertically [see 2.4].

Dismantle the blade [see 4.7].
Remove the guard 
(1)secured by five screws (2).
Unhook the engagement cable spring 
(3)and the
return spring 
(4).
Unhook the brake spring 
(5)and dismantle the
blade bracket 
(6), which is secured by two screws
(7).
Using the wrench supplied 
(12)# code 60205002/0
for securing the pulley 
(13), 
loosen the central screw 
(8)and pull out the whole
clutch unit 
(9).
NOTE
If you do not have the wrench (12) with you, you can
undo the central screw 
(8) with only an impact
screwdriver
.
For safe and reliable operation, do not attempt to
dismantle or repair the clutch unit parts.
Check that the friction surface 
(9b)of the outer ele-
ment 
(9a)is in good condition, not worn and with a
minimum thickness of 1.8 mm; otherwise it must be
replaced.
Grasp the inner part 
(9c)with both hands and

nal springs; otherwise both parts must be replaced
(

On assembly, check that the peg 
(10)fits securely in
the slot (
11)of the reaction arm.
Tighten the screws 
(7) and (8)to the amount shown.

Refit the blade [see 4.7] by tightening the nuts to
the amount shown.

6.5 REPLACEMENT OF THE DRIVE BELT

Position the machine vertically [see 2.4].

Dismantle the blade engagement clutch [see
6.4].
Remove the pulley 
(1)from the engine shaft, using
an extractor if dismantling proves difficult.
In this case, close the threaded hole 
(2)of the
engine shaft with a screw, to prevent the extractor
from damaging the internal thread.

Put the machine back on a flat surface [see 2.4].
Engage the parking brake to loosen the drive belt.
Loosen the two nuts 
(3), remove the guide pulley (4)
and free the belt (5)from the pulley (6).
Loosen the nut 
(7) of the stretcher’s idle pulley (8),
just enough to pull the belt 
(5)out of the guide pul-
ley 
(9).
At this point the belt can be removed.
On assembly, check that the belt 
(5)is positioned
correctly in the guide pulley and follow the above
steps in reverse.
When assembly is complete, ...

Remount the blade engagement clutch [see
6.4].

«STARTER» position shown on the label. Connect
the end of the wire 
(2)to the terminal (5)on the
engine after shifting the lever 
(6)to the same
«STARTER» position. This position depends on the
type of engine and is shown in the instruction hand-
book.
➤In manual start models:ensure that the
engine switches off and stops correctly when the
accelerator is set to «STOP».

(7)does not have too much play in relation to the
nut screw 
(14). If so, replace both components.
Remount the components of the caliper unit 
(10),
following the steps shown and taking care to posi-
tion the metal plate 
(15)correctly between the
screw
(13) and the pad (12a).
When screwing down the nut screw, remember to
rotate the lever by 360° to obtain the correct direc-
tion after assembly.
To reposition the caliper more easily, fit a 7 - 8 mm
block 
(16)between the pads (12a)and (12b) so that
they do not slip out of their seats during reassem-
bly.
Check that the brake disc is intact and not
deformed or worn. If it is, replace it [see 6.11.C].

(17)between
the two caliper unit pads 
(10), then line up the
unit with the pin holes 
(9);

(9a)and hook on the
spring 
(6). Bend this spring forward slightly to
insert the front pin 
(9b), which should go under-
neath the spring.
–the rod 
(5) should be positioned with the two ter-
minals bent to the right.
