cam removal problem

[Ronnie]

No, you don't have to remove that gear. I still believe there is something like a piece of the pushrod down in thet hole. I ran into it once, the owner and freands had been trying to get that cam out for days. Walt

Some don't grasp that do they Walt.

cuzncletus>>>It's not a "slow" sticking like a tight bearing but makes a pronounced ringing in the cam when the obstruction is hit.>>>

A bent cam might result in slow sticking like a tight bearing most, ***but maybe not all***, of the time. Just a thought.

CUZ----- do you know what the rear cam bearing journal looks like? The one I had did the same thing, you could pull the cam in and out with your fingers about 1/4in. and then it come to a rock wall. The rear journal has a groove all around the middle of it about 1/2in. wide, the push rod rides in that groove and goes up and down. The cam going back and forth is just taking up the slack in the width of that groove. I hope you let us know when you do find the culpret. Walt

I've had experience with damaged rear cam bearings. If the pushrod hole is not aligned correctly during bearing installation the pushrod can be forced down(hammer) and fold a small piece of the bearing into the void. This is not a problem until it comes time to remove that camshaft.

OK, let me just say that I experienced the same problem. Cam and gear spun fine, but cam would only move out about 1/4 inch. Took it to my machinist and the first thing he did was pop out the idler gear retainer. Out came the cam.

There's no harm in trying, but you guys would rather he spend his time looking for a broken fuel pump rod. Go figure.

I'm hoping it goes into intensive care today at the machine shop as Saturday is a work only day with no customers. Maybe two half wits, me being one of them, can make a whole wit and find the solution.
