Reassembling The Components; How To Use The Manual - APRILIA SR 50 Service And Repair Manual

REASSEMBLING THE COMPONENTS

a
CAUTION
Never use a circlip twice. When a circlip is removed,
it must be replaced with a new one.
When assembling a new circlip be careful not to
stretch its ends more than strictly necessary to put it
on the shaft.
After installing a circlip, make sure that it is com-
pletely and firmly inserted in its seat.
Do not use compressed air to clean the bearings.
NOTE
The bearings must rotate freely, without halting
a/o noise otherwise they must be replaced.
– Use only original aprilia SPARE PARTS.
– Use the recommended lubricants.
– Whenever possible, lubricate the parts before reas-
sembly.
– When tightening screws and nuts, begin with those
having greater diameters or with inner ones, proceed-
ing diagonally.
Tighten screws or nuts in successive passages before
applying driving torque.
– Always replace gaskets, grommets, circlips, O-rings
and split pins with new ones.
Before the assembly, clean all the connection surfaces,
the oil seal edges and the gaskets.
Apply a thin layer of lithium-based grease on the oil
seal edges.
Put back the oil seals and the bearings with the mark
or serial number facing towards the outside (visible
side).
When installing the bearings, lubricate them abundant-
ly.
– Make sure that each component has been reassem-
bled correctly.
– After a repair or periodic maintenance operation, carry
out the preliminary checks and test the vehicle in a pri-
vate area or, in any case, in a low-traffic area.
