5,12, Bearing
Always push bearing by inner race.
The bearing on the splined side of axle must be
pushed until it is seated on shaft shoulder. The
end bearing housing bearing must be flush with
end of drive axle. Each bearing must have its
shield facing the sprocket.
1. Bearing shield on this side
2. Flush with drive axle
3. Seated on shaft shoulder
AXIAL PLAY
Ensure there is no deformation of the sheet metal
around the end bearing housing. Straighten as re-
quired.
Before attempting to adjust the drive axle axial
play, check the chaincase perpendicularity as fol-
lows:
CHAINCASE PERPENDICULARITY
ADJUSTMENT
– Remove driven pulley.
– Unbolt bearing support.
– Extract bearing from its support.
Wrong chaincase perpendicularity will make it dif-
ficult to correctly install the bearing in its support
due to the countershaft and support misalign-
ment.
TYPICAL
– Add shim(s) (P/N 504 0398 00) between chain-
case and frame to obtain easy bearing installa-
tion.
This chart can be use as a “starting point” to cor-
rect the chaincase perpendicularity.
