Use Loctite 518 gasket maker for the reverse shifter plate.

Add the gaskets.

I created a simple tool to turn the kick start spring front cover.
But a large plier would also work.

Add gasket maker to the screw holes for a oil tight seal. This also works like a thread locker. No need to punch in the small holes to lock the screw as it was done before. Those three large screws only hold the reverse gear shaft and do not need much torque anyway.

Add Dirko (very sticky silicone sealer) to the end of the transmission rods. It will leak from there over time, even it is only a very small amount of oil.
Make sure the distance ring for the bearing that is hold with the (black) output shaft cover plate provide enough play.
Add the test adapter, and make a test run to make sure everything is running smoothly.

Along with the rebuild final drive, it makes for a perfect drive train.
1st and 2nd gears remain powerful with the 8/37 final drive, but 3rd and 4th now feel like they’re using a high-speed final drive, which is ideal. Previously, I had a high-speed final drive, but starting in 1st gear with a sidecar was challenging, especially on uphill climbs.
