If rolling torque measured at step 18 is too high, fit the

next larger size spacer. If rolling torque is too low, fit the

next smallest size spacer. If a correct spacer is not

available from the range, check that drive head is

assembled correctly.

Remove adapter C and sleeve B. Fit a new oil seal,

grease between seal lips before fitting. Fit the brake

calliper bracket D. Apply JCB Threadlocker and Sealer

to the fixing bolts E. Fit the brake disc/coupling and a

NEW stake nut 16.

Progressively torque tighten the stake nut, occasionally

rotating coupling yoke, up to 250 Nm. Providing the

correct size spacer has been selected the rolling torque

should be between 2.3 and 3.4 Nm including seal drag.

Note: The nut tightening torque can be increased to a

maximum of 300 Nm provided that the pinion rolling torque

does not exceed the maximum of 3.4 Nm.

Finally stake the nut 16 into the slot.

If both brake piston housings were removed, fit the one

at the opposite end to the crownwheel, using the

procedure in Step 24. Then install the crownwheel

/differential assembly into the drive head.

Apply JCB Multi-Gasket to the drive head mating face,

then fit the brake piston housing. Ensure that the match

- marks mad e d uring d ismant ling are aligned . Fit

capscrews. Torque - tighten to 56 Nm (42 lbf ft, 5.7 kgf

m). (Applies to both piston housings.)

Adjust differential side nuts to give a bearing preload of

1.13-2.26 Nm (0.8-1.6 lbf ft; 0.1-0.2 kgf m). (Measure

the preload by taking another rolling torque reading and

subtracting the torque figure measured at step 21. The

difference is the bearing preload.)
