5. Grease Fitting

Important Operations

3. Needle roller bearing

(1) Install spider to flange yoke. Be sure to install the spider by

aligning the setting marks made during disassembly.

(2) Apply a molybdenum-disulfide grease or a multi-purpose

type grease NLGI No.2 to inside of the bearing cap.

Grease Amount: Approx. 1.2g (0.042 oz)

(3) Using either  mallet (or copper hammer) or a press, install

the needle roller bearing into the yoke so that the snap ring

can be installed in its groove.

CAUTION:
The needle roller bearing cannot be installed smoothly if it
is set at an incorrect angle with the flange and excessive
hammering will damage the needle roller bearing.
