Replacing Front / Rear Wheels - GGP ITALY SPA TC 102 Série Manuel D'utilisation

All work on the cutting means
(disassembly, sharpening, balancing,
repairing, reassembly and/or replacing)
are demanding jobs that require special
skills as well as special tools. For safety
reasons, these jobs are best carried
out at a Authorised Service Centre.
Always replace damaged, bent
or worn cutting means, together
with their nuts and bolts, in order to
ensure they remain balanced.
IMPORTANT We strongly recommend
changing all the cutting means at the same
time, especially in the case of uneven wear.
IMPORTANT Always use original cutting
means bearing the code indicated in the
"Technical Data".
Given product evolution, the cutting means
listed in the "Technical Data" table may be
replaced in time with others having similar
interchangeable and operating safety features.

8.3 REPLACING FRONT / REAR WHEELS

8.3.1 Preparation
IMPORTANT Use a suitable lifting
device, for example a scissor jack.
Before changing the wheels it is necessary
to complete some preliminary operations:
• Remove all attachments.
• Position the machine on a solid
and even surface that guarantees
stability of the machine.
• Engage the parking brake;
• Stop the engine;
• Remove the key from the ignition;
• Position the jack in the lifting position near the
wheel to be changed (par. 8.3.2; par. 8.3.3).
• Check that the jack is perfectly
perpendicular to the ground.
8.3.2 Choice and positioning of the
jack on the rear wheels
Position some wooden wedges (fig. 38.A)
at the base of the wheel (fig. 38.B) next to
the wheel to be changed (fig. 38.C).
For models with rear collection:
• The maximum possible jack height
when closed is 110 mm. (fig. 39).
• Position the jack under the rear plate (fig.
40.A) at 180 mm from the side edge.
For side discharge models:
• The maximum possible jack height
when closed is 110 mm. (fig. 41).
• Position the jack under the rear axle, in the
point indicated in the diagram (fig. 42.A).
NOTE In this position the jack allows you
to only raise the wheel to be changed.
8.3.3 Choice and positioning of the
jack on the front wheels
1. Position some wooden wedges (fig. 43.A)
at the base of the wheel (fig. 43.B) behind
the wheel to be changed (fig. 43.C).
2. The maximum possible jack height
when closed is 110 mm.
NOTE Select the position of the jack
depending on the type of machine.
3. Position the jack under the front
part of the machine (fig. 44.A, 45.A,
46.A) as indicated in the figure.
NOTE The jack must be positioned under
the flat part of the support (fig. 44.B, 45.B).
NOTE The jack must be positioned under
the central rib of the support (fig. 46.B).
8.3.4 Changing the wheel
IMPORTANT Make certain the machine
remains still and stable during the lifting process.
If you notice anything out of the ordinary,
lower the jack immediately, check and resolve
any problems and lift the machine again.
1. Slide the cover off (fig. 47.A)
before raising the machine.
2. Raise it enough to extract the wheel easily.
3. Using a screwdriver, remove
the snap ring (fig. 47.B) and the
shoulder washer (fig. 47.C).
4. Remove the wheel to be changed.
5. Coat the axle (fig. 47.D) with
lubricating grease.
6. Mount the spare wheel.
7. Carefully replace the shoulder
washer and snap ring.
8. Rest the wheel on the ground
replace the cover (fig. 47.A).
