4- Thread the black trap door bearing retaining nuts snugly to the trapdoor, but do not tighten them yet.
5- Install the trap door assembly onto the countershaft and main shaft.

Note: To ensure the thrust washer behind 4th gear on the main shaft does not move, it is best to use a vertical orientation during assembly. Position the
trap door on top so it is pushing down on the cassette assembly. This can be done by supporting the end of the main shafts with a 5.425” offset. Press the
trap door onto the mainshafts using a flat plate and a press. Installation should only require a small amount of force, less than 1,000 lbs. See Picture 16.

Do not use excessive force to install the trap door assembly on the main shafts. Excessive force will damage the bearings in the trap door.
