REPAIRS
This chapter deals with all the more complex work connected with the replacement or repair of malfunctioning or
worn parts.
The descriptions proceed by necessity in a logical way and can include operations not specifically connected to a
particular type of repair.
In this case, careful reading of the entire procedure can help you omit all those operations not connected with the
case in hand without, however, overlooking anything that may be necessary.
Timings for these items of work are shown in chapter 1.6.
6.1
Replacement of tyres and wheels
NOTE:
The tyres used are tubeless. Consequently, if a tyre
is punctured, it must be repaired by a specialized tyre repairer
in accordance with the procedures prescribed for this type of
tyre.
NOTE:
After replacing one or more tyres, the cutting deck
should be checked to ensure that it is parallel (see 4.4).
·
Replace deformed wheel rims in order to ensure
satisfactory performance of the tyres.
a. Front wheels
1. The front wheels are held by retaining ring [1] that can be
removed with a screwdriver.
2. When fitting, smear the pin with grease and replace the
shouldered washer [2].
b. Rear wheels.
NOTE:
If a wheel is jammed on the axle, use a penetrating oil
spray, directing the jet towards the keying groove.
When re-assembling, smear grease over the shaft, which will
help the next time the wheel needs to be removed.
Up to serial n° 8700563:
1. The rear wheels are directly attached to the differential axle
shaft with a spline [3] and held by a screw [4] with its nut
[5].
2. When fitting, first check that the key and its seat on the axle
are in good condition and, then, smear grease on the shaft,
insert the key and push fully home until it clears the hole for
the screw [4].
3. Put in the screw [4] and lock the nut [5] to the amount shown.
