ivasher on the pinion shaft. (Apply a

small amount of lubricant on the

washer side of the nut.)

10.
Hold the flange with the tool

shown in Fig. 9 while the nut is being

tightened.

11.
Tighten the pinion shaft nut,

rotating the pinion occasionally to in-

sure proper bearing seating, (Fig. 6)

and take frequent preload readings

until the preload is at the original rec-

orded reading established in step 3.

12.
After original preload has been

reached, tighten the pinion nut slowly,
until an additional preload of 6 to 12

in-lbs has been added.

The preload should not exceed the

amount shown above, or bearing fail-

ure may result.

Under no circumstances should the

pinion nut be backed off to lessen pre-

load. If this is done, a new pinion

bearing spacer must be installed. (In

addition, the U-joint flange must

never be hammered on, or pneumatic-

-tools used.)
