Inspect Reel
1. Replace reel if diameter has decreased to the service

ing compound (Loctite 242 or equivalent). One side
is L.H. threads and the other R.H. threads (R.H. has
identification groove on outer surface of flange). To
remove or install threaded spline inserts, use tool

equivalent to threads and tighten to a torque of 75 –
85 ft–lb (10.4 – 11.8 KgM)
4. Inspect bearings and seals. To replace seals and
bearings:
A. Use a bearing puller tool to remove the bearings.
To prevent damage to bearings, pull on the inner
bearing race. Remove the seals. NOTE: If bearing is

seals are installed square to shaft.
C. Pack bearings with No. 2 general purpose
grease before installing. Install bearings on reel
shaft by pressing on the inner bearing race.
