OK, a little background. I am installing a hydraulic roller cam, got the cam in, installed the timing chain and cam button bearing. Next need to make a nylon plug to put in the center recess of the cam button bearing.

Well tonight I finally get a chance to do some measuring and I find out the stock GM cover is not deep enough! The bearing is taller than the depth of the cover. This is driving me nuts, it's one snag after another. I think I'll just machine a button from Nylon and give up on the fancy roller (that won't fit).

I don't know why I didn't do this to begin with. Thoughts?

Just get an aftermarket cover that fits your application. You cannot be the first person with this problem.

I don't have clearance behind the water pump for a deeper cover. Cloyes makes one, been there done that. I will just make a lower profile button. I'm just bitching about the snags I keep running into trying to do something very simple. It's driving me nuts, that engine was supposed to be together last month.

Sounds like it will work, but be sure to have between.003-.008 clearance between the button & cover, because the cover metal will expand.
P.S. HI GUYS!!! :cheers: :cheers:

I used this one:

It fits behind the short pump and has a roller cam stop built into the cover. Best part is that it's adjustable without taking the cover off. I did have to grind the flange slightly to fit my Edelbrock water pump. A GM pump probably fits without modifications.

Looks like the .800 one would work but these were my choices when I bought my cam from Summit:

Of the 10 listed there all are .925-.950 (exept one .640 button). The Lunati that was sold to me is .950 and my cam is a Lunati. Well it's done now, I machined the button at work today.

Is that top gear machined for a Torrington bearing??

I thought you just grind them down to the size you want :thumbsup:
