Disassembly





1. Remove detent spring plate and gasket (1), detent spring (2) and detent ball (3).
Use a magnetic hand to remove the detent balls from the intermediate plate.





2. Remove spring (4).
3. Remove rev-5th shift rod (5), and rev-5th shift arm and reverse inhibitor (6).
Remove 1st-2nd shift rod (7), 3rd-4th shift rod (8), 3rd-4th shift arm (9), and 1st-2nd shift arm (1 O).





- Hold a round bar against the shift rod end.





- Use a spring pin remover to remove the shift arm spring pins from the shift arms and the shift rods.
- Move the 3rd-4th shift rod forward.
- Remove the rev-5th, 1st-2nd and 3rd-4th shifter rods carefully. Interlock pins are located between the shifter rods in the intermediate plate.
4. Remove interlock pin (11) from intermediate plate and gear assembly (12).

Inspection and Repair
Make the necessary adjustments, and part replacements if excessive wear or damage is discovered during inspection.

Shift Arm Thickness
- Use a micrometer to measure the shift arm thickness.
If the measured value is less than the specified limit, the shift arm must be replaced.

Detent Spring Free Length
- Use a vernier caliper to measure the detent spring free length.
If the measured value is less than the specified limit, the detent spring must be replaced.








Detent Spring Free Length

Detent Spring Tension
- Use a spring tester to measure the valve spring tension.
If the measured value is less than the specified limit, the detent spring must be replaced.
