assistant guides shaft assembly (27) from
gear housing (21).
A correct gear pattern for a used pinion and ring gear is clear of toe and centers evenly along face of
gear tooth, but can be any length and shape and is acceptable as long as pattern does not run off gear
tooth at any point.
If gear pattern was correct at disassembly, then gear pattern after assembly should be the same.
Remember, a correct gear pattern for a used pinion and ring gear does not have to match PATTERN
A (correct pattern for new gearing).
If new pinion and ring gear are used, tooth pattern should be like correct PATTERN A. If tooth
pattern does not look like A, check pattern B through E to find one that looks close to ring gear
tooth pattern, then do step that follows incorrect pattern.
CORRECT PATTERN (NEW GEARING)
(32) Read dye pattern on ring gear (1).
(33) If tooth contact is like PATTERN A, do not adjust. Go to step (40).
