You cannot get a thickness gauge between the rotary disc and back plate. Oil it so there is an oil film in the gap and adjust it by feel. Should have a slight drag. Under no circumstances should you be able to feel any in/out play of the rotary valve on the pin.

how to mount rear bearing???

Four Stroker

But the case in the oven at 250~300F and bake for 20 minutes. The rear bearing will fall out with the crankshaft.
