1. Remove back-up light switch and cable bracket. Remove transmission attaching bolts, and disconnect breather tube. Remove 32-mm sealing plug (plug has square hole). Expand snap ring on countershaft ball bearing. Separate transmission housing from clutch housing.
2. Measure clearance between reverse shift fork and shift piece pin.Clearance should be .002-.014" (.05-.35 mm). Service limit is .020" (.50 mm). If clearance exceeds limit, measure width of "L" groove in reverse shift fork. Width should be .278-.285" (7.05-7.25 mm). Replace reverse shift fork if width exceeds specification.
3. Measure clearance between reverse idler gear and reverse shift fork. Clearance should be .020-.043" (.50-1.10 mm). Service limit is .071" (1.80 mm). If clearance exceeds service limit, measure width of reverse shift fork pawl opening. Width should be .500-.512" (12.70-13.00 mm). If width exceeds limit, replace shift fork.
4. Remove reverse shift fork. Remove reverse idler gear shaft and gear. Remove interlock guide bolt from under clutch housing. Remove shift arm "B" bolt. Tape mainshaft splines for protection.
