d. Remove nut (B, Figure 7-41), sleeve A, outer
bearing 46 and install correct size spacer 44. Take
care to avoid damaging the outer bearing.
NOTE: In order to remove bearing 43, the output shaft 41,
Figure 7-38 must be removed. Due to ratio options
some transmissions feature a larger diameter
output gear. When removing the output shaft the
gear may contact the gearbox housing, preventing
removal. For shaft removal procedure, see Output
Shaft (Larger Diameter Gear).
e. Install sleeve A and initially tighten nut B to
approximately 50 Nm (37 lb-ft). Check that there is
no end play and rolling torque is less than 1.5 Nm
(1.0 lb-ft).
f. If the rolling torque measured is too high, install the
larger size spacer. If the rolling torque is too low,
install the next smaller size spacer.

6. Position the transmission vertically on wooden blocks to
provide clearance for the input shaft. Install bearing cups
into input and forward positions. Coat the pump end
bearings with a Lithium Base, E.P. No. 2 bearing grease.
Then carefully lower input clutch (V, Figure 7-43) and
forward clutch P into casing.

Remove nut B and sleeve A, Figure 7-41. Install a
new seal 42 (apply grease between the lips before
installation). Assemble the parking brake flange (38)
(the flange may be a tight fit).
Do not excessively hammer on the flange during
assembly because damage to the shaft bearings
could occur. If necessary, press fit the parts. Fully
support the shaft during assembly.
and progressively tighten to a torque of 300 Nm
(221 lb-ft). Provided the correct size spacer has
been selected, the combined seal and bearing
rolling torque should not exceed a maximum of 2.0
Nm (1.5 lb-ft) when the nut is fully tightened to
proper torque.
If the rolling torque measured is too high, install the
next larger size spacer. If the rolling torque is too
low, install the next smaller size spacer.
Finally, stake nut (40) into the slot on the shaft.
To inhibit damaging the input shaft piston ring seals
(46), it is permissible to remove the seals prior to
assembling the case halves. However, this is
applicable only while measuring the shaft end play.
