Wheel Hub Assembly
Removal
The procedure is the same for all four wheels.
It is assumed that roadwheels are removed and the machine
is correctly supported.
Place a suitable receptacle under the wheel hub to collect
the oil from the chain case.
Slacken, but do not remove, hub nuts B (6 off) on retaining
ring C and allow the chain casing to drain completely. Fit a
large adjustable spanner to the boss D and rotate the hub
assembly until D is horizontal and pointing to the front of the
machine (front wheel) or to the rear of the machine (rear
wheel). In this position the drive chain is at its slackest.
Remove the nuts and washers B and the retaining ring C.
Pull the hub assembly out and remove the chain from the
sprocket E. Remove the hub assembly from the chassis.
Remove and discard seal F.
Replacement
Replacement is a reversal of the removal procedure. Ensure
that the bolts G are correctly and securely fitted in the
mounting lugs.
A new 'O' ring F must be fitted. (Grease with JCB MPL
Grease.)
Adjust the drive chain (see Section 3, Routine
Maintenance)
Torque tighten nuts B to 98 Nm (72 lbf ft, 10 kgf m).
Refill the chain case with the correct oil (see Section 3,
Routine Maintenance).
