How to get the drive pulley and coupling off the shaft

1969 Ariens Mod. 10954
I want to replace the two bearings on the shaft between the driven sheave and the friction wheel drive plate.
Trying to figure out how to get the driven sheave off. Does the jaw coupling just unscrew from the shaft ??
I have the parts diagram and I don't see any pins on the back side and physically there is no bolt in the end of the shaft at the belt pulley. There are threads in the jaw coupler.

Any one done this before ??

Make sure the windows are up before the snow plow goes by !!

Once the cap screws that hold the jaw to the face of the sheave are removed, the jaw can be unscrewed from the shaft. These are "reverse" threaded so that they won't loosen during rotation. Also, they can weld themselves to the threads over time so you may need to use some Kroil or PB to loosen them up a bit. Hope this helps. MH
