05 October, 2024


Before the gear shaft gets installed, use a reamer to slightly remove the uneven wear caused by the clutch push rod. This is a common place for oil leaks.


Put in the transmission rod half way for the reverse gear shifter.


Slide in the reverse gear shifter.


Insert the input shaft and make sure it spins freely.
The bearing has pieces of aluminium foil glued on for a perfect fit.


Insert the reverse gear shaft.


Insert the output shaft. What works best is to put in the individual gears first on a small rod. Then push the axle through once all gears are in place.


All gears should perfectly match.


Put in the gear change transmission rod along with the gear forks.


Put in the plate and shaft assembly.


The other end of the plate and shaft assembly needs to go to the reverse shifter plate.


Add the distance bushing.



Add gasket maker to the gasket on both sides. This fills in minor gaps for an oil tight seal.


And carefully tighten the cover.
