BEFORE DISASSEMBLY
- Remove dirt, mud, dust and foreign bodies from the
vehicle before disassembling the components.
- Use all the tools specifically designed for the vehicle.
DISASSEMBLY
- Before separating pipes or wires etc. (joints and
junctions) mark each part with a unique marking.
Each piece should be clearly marked for reassembly
purposes.
-Clean and wash the disassembled components with
close to non-inflammable detergent.
-Keep paired parts together, because normal wear and
tear create a natural pairing. In some cases, where
one part is replaced the other must also be replaced.
Keep away from sources of heat.
REASSEMBLY
Never re-use a snap ring. If removed, replace it with
a new ring. If a new ring is fitted, do not stretch
more than necessary when fitting it to the shaft.
Afterwards, check that the ring is properly fitted to
the housing.
Do not clean bearings with compressed air.
IMPORTANT Bearings must rotate freely, without
sticking or noise. Replace if necessary.
- Use only ORIGINAL Aprilia SPARE PARTS.
- Stick to the oil chart and recommended wearing parts.
- Wherever possible, lubricate parts before
reassembling them.
- When tightening screws and nuts begin with the
largest diameters, or inner nuts and screws, and
tighten diagonally. Tighten each before finally
tightening to the specified torque.
- Always replace gaskets, gasket rings, snap rings, O-
rings and split pins with new ones.
- Clean all joint surfaces, oil seal edges and gaskets
before reassembling.

Chapter.1
- Lightly smear the edges of oil seals with lithium based
grease.
- Refit the oil seals and bearings with the trademark or
manufacturer’s serial number facing outwards (so it
is visible).
- Grease the bearings fully before fitting.
- Check that all components have been reassembled
properly.
After a maintenance or repair operation, carry out
preliminary checks and commission the vehicle on
private property or in a low traffic area.
