12hp rebuild question

Recommended Posts

RUMBLEFISH

Well I will try to explain the problem I am having. This is my first tear down of any engine so I'm a bit stumped. I am in the process of tearing down the 12hp synchro out of my b212 to have it bored out to the size 14hp piston and valve work to send to a shop.

What is the trick to pull the cam shaft out. In the manual it says to tap it out but the inside gear hits the lobe before I can get it all the way out. The re builder says I need to get it out so he can knurl the quids or whatever for the new valves.

What am I doing wrong.

And this will be on of many questions as I attempt to put this back together.

Thanks-Rick

On outside of block look where the cam shaft is it there you will see a pin you have to use a punch and the pin will come out other side of the block. I think it will only come out 1 way if you tap it you will know
