REAR FORK
DISASSEMBLING REAR FORK
To disassemble rear fork, first remove following assemblies:
1. Rear wheel (see Section 2C).
2. Rear brake side cover with connecting control linkage (see Section
2G).
3. Rear shock absorbers (see "Shock Absorbers").
See Fig. 2F-20. Turn back locking ear on pivot bolt lock washer (2) and
turn out pivot bolt (1). Remove fork (3) from frame. With appropriate
size arbor pin, push out bearing spacer (4), bearing seal (5) and
bearing with outer race (6) from each side of fork pivot bearing.
INSPECTION AND SERVICING
Clean pivot bolt hole in fork and bearing parts. Check for wear of
bearing, bearing race and bearing seal.
ASSEMBLING REAR FORK
Press outer bearing races into fork. Grease bearings with
Harley-Davidson "Grease-All" grease and insert. Apply additional grease
to outside face of bearing so that space between bearing and seal will
be filled when seal is installed. Grease bearing seals in groove between
sealing lips and press into place. Put bearing spacers over seals.
Assemble pivot bolt with lock washer and tighten bolt to preload
bearings one to two pounds as follows:
With bearings free, weigh extreme rear end of fork by attaching a spring
scale and raising the fork to a horizontal position. Tighten bearing
pivot bolt just
enough to increase bearing drag one to two pounds.
For example, if fork with bearings free weighs four pounds, tighten
pivot bolt until fork movement to horizontal position registers five to
six pounds on scale. Lock pivot bolt lock washer.
