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.
