Right Hand Rotation Unit: 3A-27
Example [A]
Incorrect topside toe contact.
Correction measures.
• Decrease thickness of forward gear shim.
• Slightly increase pinion gear shim thickness.
CAUTION
Do not set tooth contact in this position (top
side toe contact). Damage and chipping of
the forward and pinion gears may result.
Example of incorrect
Example [B]
Incorrect bottom side toe contact.
Correction measures.
• Increase thickness of forward gear shim.
• Slightly decrease pinion gear shim thickness.
CAUTION
Do not set the tooth contact in this position
(bottom side toe contact). Chipping of the
pinion gear may result.
Example of incorrect
Rechecking driveshaft thrust play
After obtaining optimum tooth contact, driveshaft thrust
play should be measured.
1) Affix the gear adjusting gauge to the driveshaft.
Special tool
(A): 09951–09530 (Gear adjusting gauge)
2) To check driveshaft thrust play, push the forward
gear inward and hold it in this position.
Push the driveshaft down completely, then slowly
pull the driveshaft up and read the maximum thrust
play.
Designate this amount of play as “A”.
NOTE
Driveshaft thrust play “A” must be known to
adjust reverse gear shim.
Driveshaft thrust play
