cb550 countershaft bearing removal
« on: July 23, 2015, 07:35:36 PM »
Hi all-

I want to clean the rust off the countershaft where the sprocket mounts on my cb550 engine. I figured I'd take the bearing off so I don't get any dirt in it, but it wouldn't budge by tapping on the inner race. The snap ring is off, so I assume it must be pressed on there.

Is there an easy way to get this bearing off (without destroying it), or does it require a special tool?

Thanks!

In case anyone needs to do this in the future, here's how I took it off.

The bearing is indeed pressed on there, I doubt it would've come off by tapping the inner race with a flathead screwdriver.

Went to home depot and got a 1 1/4" piece of black pipe. The fat part of the countershaft on the outside of the bearing is 1.3", the pipe inner is 1.38", so made 4 cuts on the end of the pipe and hammered it gradually to shrink. Spot welded it, which seemed overkill at first but I was glad I did it because it took some hammering to move the bearing.

Bearing came off in one piece because I could now apply force evenly on the inner race. It was tight about half way through the shaft, then it let go.

Hope I can get it back on there after I freeze the shaft ;)
