Cambearing install
SBC: what is the best way to install the cam bearings (have the tool to do it with). Novice at this. The tool has the cone type plug and the one to push the bearings in. The cone type one can also be pushed into the bearing one in order to keep everything square, but that would mean I need to get the first one installed and how do you then keep that bearing square to the bore?
Re: Cambearing install
You install the back one from the front, then the front one from the back....using the cone. If we're on the same page here, or talking about the same tool?

Re: Cambearing install
One piece of advice (ok 2) ... be sure to slightly chamfer the block so that the edge doesn't shave the back of the bearing.... and of course get the oil hole lined up correctly.

Re: Cambearing install
Another piece of advice. Put the bearings in one at a time. I start from the back and work my way forward. After each bearing try the camshaft in it. That way if you get one that is tight and needs scraping you will know which one was the culprit. Also make sure you put the oil holes in the proper position. Should be around 2 oclock facing the front of the engine like it sits in the car.

Re: Cambearing install
also stand the block upright on the floor to do the deed. this really simplifies things as gravity takes care of the hard part.

Also thanks for all the tips.
Re: Cambearing install
I made my own SBC installer with the end of an old cam then I took a upper timing gear ground it down to just bigger that the cam. bolt it all together using a 5/8" half inch socket with a long extension to drive the bearing in. All worked well until I bought some durabond bearings that were too tight and the cam would not spin at all (should have checked prior) so I put Enginetech brand in, all is good now.

Re: Cambearing install
I don't understand this illustration. On a V8, there's two "loads", the left lifter bank, and the right lifter bank, plus the minor issue of the cam gear/timing chain pulling down particularly on the front cam bearing.
Point is, which "load" are we setting up for?

Re: Cambearing install
The illustration shows bearing hole is preferably located so the rotation of the cam pulls the oil into the load points you mentioned.
Re: Cambearing install
Look at where the old bearing is worn and figure it out.Schurkey wrote: ↑Wed Oct 26, 2022 5:12 pm
