the camshaft is hollow and the smaller shaft extends out the sides of the case for the timer and the water pump.

the pump eccentric end has a key but wont come off, the shaft wont move within the camshaft in either direction. I am not sure which way it is intended to come out and do not want to take any risks.

what is the way this comes apart?

thanks

ok, update, I got a couple offline replies as no one is 100% sure about the way this is supposed to come apart, so I will leave the camshaft in place and manually clean and paint the outside of this housing.

I can only do that because the bushings seem to have an acceptably small amount of play. hopefully they won't seep oil too much, and I'm not sure how they are sealed.

if anyone sees this topic who has actually taken one down, it would be nice to post the knowlege here for anyone who does not have the option and has to replace the bushings.

(a search didnt find anything about this)

Did you mark the cam in some manner so it can be put back into the proper relationship with the crankshaft; timing it to the crank?

We noted that. additionally I have the document how to time the YT camshaft (which I just realized explains some of the assembly):
