position of the spider pin relative to the
journal yoke ears on the propeller shaft
joint. This will ensure correct assembly and
reduce the possibility of imbalance.

4. Remove the circlips.
5. Tap the yokes to eject bearing cups. Remove

bearing cups.

6. Remove spider from yokes.
7. Clean yokes and bearing cup locations.

Reassembly

yokes.

4. Partially insert one bearing cup into yoke and

enter spider trunnion into bearing cup.

5. Insert opposite bearing cup in yoke.
6. Press both cups into place.
7. Press each cup into its respective location in

yoke up to lower land of circlip groove. Damage
may be caused to cups and seals if cups
pass this point.

8. Fit circlips and check no end float exists.
9. Engage spider in second yoke. Fit bearing cups

and circlips as described in steps 4 to 8.
