Gear Pattern Movement Summary - Toro Reelmaster 5500-D Service Manual

Gear Pattern Movement Summary

Every gear has a characteristic pattern. The illustrations
show typical patterns only and explain how patterns shift
as gear location is changed.
1. If contact is toward the heel or base of the gear (Fig.
41):
A. Install thicker or additional bearing case shim(s)
to move pinion shaft toward ring gear.
B. Install thinner or remove differential bearing
shim(s) to move ring gear backward.
C. Repeat until proper tooth contact and pinion gear
to ring gear backlash are correct.
2. If contact is toward the toe or tip of the gear (Fig. 42):
A. Install thinner or remove bearing case shim(s) to
move pinion shaft away from ring gear.
B. Install thicker or additional differential bearing
shim(s) to move ring gear forward.
C. Repeat until proper tooth contact and pinion gear
to ring gear backlash are correct.
