CLEANING, INSPECTION AND REPAIR (Figure 4-11)

Clean all parts excepi camshaft oil seal (9) and leather washer (15) in solvent and blow dry with compressed air.

Inspect shifter lever fit in bushing (17). If there is considerable side play, replace bushing as follows. Thread a 5/8 in. tap into bushing about 1/2 in. deep. Remove tap and heat case around bushing to about .300 degrees F. Replace tap and clamp in vise. Tap cover with rawhide mallet or block of wood and hammer until cover is driven off bushing. Press in new bushing.

Inspect gear teeth on shifter cam and shifter gear. If wear is deep, replace parts. Slightly worn parts may be used safely with no impairment to proper function.

Inspect neutral indicator switch. Depress plunger in base of body. It should spring back without a bind. If neutral indicator light fails to light in neutral position, plunger is sticking Switch cannot be repaired, it must be replaced. Do not test switch by passing current through it without having a neutral indicator bulb in the circuit series.

Inspect spring and cam follower. If tip of cam follower is rounded, replace it. To function properly, cam follower must have a reasonably sharp tip.

ASSEMBLING SHIFTER COVER (HAND SHIFT) (Figure 4-11)

It is necessary to time shifter lever gear (12) to gear on shifter cam (10). Install shifter gear spring (13) and shifter gear (12) in cover with spring located over gear hub and timing mark between gear teeth to outside (facing cover bushing). Install shifter cam (10) so notch in gear tooth is aligned with timing mark on shifter gear. Install shifter lever and shaft assembly (14), with square end of shaft in hole in gear with shifting lever pointed toward left, front screw hole in cover, and leather washer (15) between lever and cover bushing.

Insert cotter pin (11) in shaft hole.

Place shifter cam in cover with timing mark on tooth registered with timing mark between teeth on side of shifter lever gear.

Install shifter camshaft (8) and secure with lock screw (7). Be sure oil seal is in place with widest groove in right end of shaft. Shifter cam end play should be 0.0005 in. to 0.0065 in. If greater, install shim washer of desired thickness. If less than desired amount, file boss in case until recommended play has been achieved.

Install cam follower (6), spring (5), lockwasher (3) and cam follower retainer (4). Bend ear of lockwasher against flat on retainer.
