IL•IINSPECTION
AND REPAIR
Make necessary correction or parts replacement if
wear, damage,corrosion or any other abnormal
condition is found through inspection.
NOTE:
When any part of the journal assembly (spider,
needle roller bearing, grease fitting) requires
replacement, be sure to replace the entire assembly.
Visual check
Check the following parts for wear, damage, noise or
any other abnormal conditions.
• Spider
• Needle roller bearing
• Yoke
• Flange

install the needle roller bearing into the
yoke so
that the snap ring can be installed in
its groove (Fig. 4A-18).
CAUTION:
• The needle roller bearing cannot be installed
smoothly
if it is set at an incorrect angle with
the
flange.
•
Excessive hammering will damage the
needle roller bearing.
IE41 3) Align setting marks and join the yokes.
NOTE:
Assemble the spider and spline yoke so that their
grease fittings are arranged on the same side
(Fig. 4A-19).

NOTE:
Discard used snap rings and install new ones.
I§EI When the bearing cap is in position, select and

of the spider pin is held within 0.1 mm
(0.004 in).
