Wheel Hub Assembly
Dismantling
It is assumed that the roadwheels have been removed and
the hub assembly removed from the chain case.
The numerical sequence is a guide to dismantling.
Remove bolts
1
(8 off) and drive sprocket
2
. Support the
assembly on face
3
and press out the stub axle assembly
4
.
Bearing
5
will remain in the casing
6
, and can be removed
separately if necessary. The bearing cap of bearing
7
will
also be left in the casing and can be removed if necessary.
Shaft seal
8
should be removed from the stub axle
4
and
discarded. Examine the stub axle and casing for wear or
damage.
Assembly
The numerical sequence shown in the dismantling procedure
should be reversed.
Lubricate all bearings and seals with JCB Special MPL
Grease before assembly.
When assembling the sprocket note that it is dished to offset
the teeth from the mounting face. Therefore, on the front hub
the sprocket teeth should be furthest from the housing, on
the rear hub the sprocket teeth should be closest to the
housing. If the sprockets are not assembled correctly the
drive chains will not line up.
Clean the mating faces of the sprocket and hub before
assembly using JCB Cleaner/Degreaser. Apply JCB Retainer
(High Strength) to the stub axle mounting face and place the
sprocket onto the stub axle.
Apply JCB Retainer (High Strength) to bolts
1
. Tighten
evenly to the correct torque in a diagonal sequence whilst
rotating the hub to seat the bearings.
Note:
The torque required to rotate the hub after assembly
should be no more that 30 Nm (22 lbf ft, 3 kgf m).
