Oooooooooh, that was fun watching that guy destroy his cam bearings removing/installing the cam. :sigh: It kills me watching people spin/rotate camshafts when installing or removing them. If you have it perfectly level and hunt around with grace, the install you should never have to do that..

As far as I know, 9 months later the truck is still running fine... What's the science behind turning the camshaft during install destroy the cam bearings? I don't think I've ever heard that.

No shit, what a tard. I always use a 10+" 3/8s extension inside the cam shaft to get the first set of journals out to get some leverage, and the same when getting the last set of journals back in.

Knick a cam bearing and the bearing will sieze to the cam journal. A nick in any bearing surface is liable to cause gauling and sieze the bearing to whatever is rotating inside it. In this case a cam journal.

Well I guess my cam bearings are fucked then :eyes::eyes::eyes:

Turn that cam lobe while it's on a bearing, then remove the cam and look at it. That nice sharp edge on the lobe will put a nice gouge in your bearing surface. I never ever ever let a lobe touch a bearing. If you need to rest or take a break installing the cam, make sure the journal rest on the bearing, nothing else. Nothing else should touch a bearing other than the journal. If it does, you're more than likely causing damage to the bearing.

Lol what an idiot:bang:

I never said to do it exactly like he did, but it shows the basics
