Last night I installed my first set of cam bearings. It was pretty simple, like the guys said.
One question tho.
On the rear bearing, when the bearing is driven home to the point where the hole lines up over the groove, it seems like it might be too far to the rear. Because after I slipped the cam into place and bolted the sprocket on the front, I looked at the rear bearing and it was sticking back past the end of the cam journal by about 1/4".
Is that normal?

Thanks for all the help

 

Okay, I had to work with the rear bearing to get it right. Apparently I drove it too far back the first time.
What I'm wondering now is after all the playing around with it that I've done, is it possible that the bearings fit in the block has been loosened up a bit, possibly to the point where it would be at risk of spinning?
The cam I'm using is pretty mild, if that makes any difference. The springs are some new stock replacements, I think.

Thanks again

 

don't think you have anthing to worry about. i'd moved bearings around a bit, even reinstalled one or two and never had a problem

 

That's exactly the sort of first hand testemonial I was hoping to hear!
Thanks ede.
I noticed that after moving it one way and then the other, and back again it didn't take as big a hammer to make it move.

Another question. What causes a spun cam bearing?
If a cam bearing spins is the block destroyed?

Thank you

 

a bearing would spin when there is no oiling and it "welds" to the crank, cam, or whatever and then spins in it's bore. when a bearing spins the block, rod, etc is trash.
