Examine ball stud seat and ball stud for scores or wear.
Worn seats can be replaced using a replacement kit
consisting of three seats, one spring, a washer and
seal. Since the ball stud is an integral part of the
propeller shaft yoke, any scoring or wear of the ball
will require replacement of the entire propeller shaft
yoke and flange assembly.
1. Thoroughly clean ball seat cavity. Proceed as follows:
NOTE: Inspect ball seat cavity. If the ball seat
bore is scored or worn, replacement of the pro-
peller shaft assembly will be required.
2. Pack spring cavity with grease supplied in repair
package.
3. Install spring, washer, ball seats and spacer. Apply a
thin coat of non-hardening sealer to the outer diame-
ter of the seal and install the seal with the lip towards
the seat using Special Tool J 23694, (Fig. 4E-18).
4. Stake the seal lightly in four places in the same loca-
tion as staked prior to removal. Use care not to over-
stake so as to damage or distort the seal.
5. Install bearings and journals as described in steps 1
thru 5 of B above, making sure to align punch or
scribe marks on yokes (Fig. 4E-12).
