Shifter Forks

REMOVING SHIFTER FORKS (Figure 4-15)

Remove shifter cover and transmission side cover as described in "Removing Shifter Cover."

On early 1976 and earlier models, shifter fork shaft (2) is held in position by lock screw (1) which may be found in gear box cover joint surface in line with right end of shaft. On late 1976 and later models, shaft is held in place with a lock ring (1 A). With lock screw or ring (1 or 1 A) removed, shaft may be driven out by means of a drift inserted in hole in starter cover joint face of gear box. Notice that a rubber oil seal (3) is assembled in groove on left end of shifter fork shaft.

Shifter fork assemblies (A and B) are not interchangeable. Note exactly the arrangement of parts and components in each. Keep parts separate to avoid needless adjusting when reassembling. If inspection shows fork assemblies are not damaged, worn or bent, it may not be necessary to disassemble them unless shifter clutches are replaced. Adjustments are described in "Assembling Shifter Forks."

DISASSEMBLING SHIFTER FORKS (Figure 4-15)

If it is necessary to disassemble shifter forks, lift off shiftei finger rollers (4), pry back ear on lockwasher (6) and turn ofl nut (5). Remove washer (6), shift forks (7,8 or 8A), 5/64 in thick standard spacing shim (9), more .007 in. or .015 in spacing shims (10), Shifting fingers (11) and shifting fork bushings (12).

CLEANING, INSPECTION AND REPAIR

Clean all parts in cleaning solvent and blow dry with compressed air.

If shifter forks are bent or worn, replace them. Straightened forks are weak. They may break and cause extensive damage to gear box parts.

Check fit of shifter fork bushings on shaft. If bushings are loose enough to give fork action lash, replace them. Check replacement part fit on shaft.

Lap out bushings or shifting fingers if they bind. Shifting will be difficult unless they work freely on shaft.
