    The Cloyes gear drive I have on the front of my SB400 did not have a cam button with it on the previous motor it was on. It also didn't have the brass washer/bushing that sits behind the cam gear.

    If I just leave it as it is now, won't the cam walk back and forth when it's running?

    IT isn't a roller cam is it? I'm pretty certain non roller cams have a design in them that pushes them back into the block. A block protector bearing is always a good idea though. The bearing taht goes behind the cam gear that is.

    It's a non-roller Comp Cam. I can take the cam gear and move the cam foreward and back some. I've had motors I've pulled apart where you can see the imprint of the cam gear rubbing on the timing cover.

    Yes it will walk back and forth screwing up your timing as it goes. I had this problem in my little blazer with a 305. The motor I pulled the gear drive off of didn't have a cam button so i didn't think I needed on, Boy was I wrong every time it was put under load the timing would either advance too far or retard to far and the dang thing would die. (Not good on the trails when your trying to climb any thing bigger than an ant hill)

    So, you can just buy an individual cam button? Probably a stupid question. I don't know cause I never go in to try and buy new stuff.

    Yeah the store I work at stocks the bearing type ones. They're about $10.
