Drive Head Maxtrac - Assembly (cont'd)
24 Progressively torque tighten stake nut K, occasionally
rotating coupling yoke, up to a minimum of 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. When the torque is correct, stake
the nut to the pinion shaft using a square-ended staking
tool.
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.
25 If both brake piston housings were removed, fit the one
at the opposite end to the crownwheel, using the
procedure in Step 16. Then install the crownwheel
/differential assembly into the drive head.
26 Apply JCB Multigasket to the drive head mating face,
then fit the brake piston housing. Ensure that the match
- marks made during dismantling are aligned. Fit
capscrews. Torque - tighten to 56 Nm (42 lbf ft, 5.7 kgf
m). (Applies to both piston housings.)
27 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 24. The
difference is the bearing preload.)
