Transmission Cover

Disassembly

1. Using a small punch, drive out pins retaining 1st-2nd and 3rd-4th shifter forks to shifter shafts and also drive out expansion plugs. The pin retaining the third and fourth shifter fork to the shaft must be removed, and the shifter fork removed from the cover before the reverse shifter head pin can be removed.
2. With shifter shafts in neutral position, drive shafts out of cover and shifter forks.

Notice: Exercise care so shaft detent balls, springs and interlock pin located in the cover are not lost as the shifter shafts are removed.

3. Drive out pin holding reverse shifter head and drive out the shaft.

Notice: Exercise care during shaft removal since detent balls are under spring tension in the rear rail boss holes.
