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

and check for run-out by holding the probe of a dial
indicator in contact with the center part of the shaft.
If the amount of run-out is beyond the standard value
for assembly, correct with a bench press or replace the
shaft
with a new propeller shaft assembly (Fig. 4A-14).

r:::1 • Be sure to install the spider by aligning the
t.=.l setting marks made during disassembly.
2. Needle Roller Bearing
c=::l 1) Apply a molybdenum-disulfide grease or a
D multi-purpose type grease NLGI No. 2 to
inside of the bearing cap (Fig. 4A-17).
Grease
Amount g (oz)
Approx. 1.2 (0.042)
2) Using either a 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 (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).
1. Snap ring
NOTE:
Discard used snap rings and install new ones.
I§EI When the bearing cap is in position, select and
- attach a snap ring
of suitable thickness so that the
end play
of the spider pin is held within 0.1 mm
(0.004 in).
