Removing rear wheel bearings
« on: April 06, 2009, 03:41:17 PM »
Does anyone have any tips or tricks for removing the wheel bearings?  I looked in the FAQ and did a search but didn't find anything.   Should I heat the hub with a heat gun? This is a 78 CB750F with Comstars.

Thanks,
Mike

I have 550, so I'm not sure about the 750's, but after I got my bearing retainer off, I simply used a piece of 1/2" steele rod and pounded them out.  You have lay thh wheel down and go throu the top.  You can use the rod to pry the bearing spacer over a little so you can get a lip on the bearing down below.  Once you do that, start pounding (within reason of course).  It took a couple cracks before mine moved at all.  Switch to the other side of the bearing and repeat. Switch, repeat.  Once you get the one side out, the other is much easier.

I think I remember something about the 750's having three rear bearings?  I have no idea.  The 550 only has two.

Hope this helps.  I hope I'm not way off here.

Get yourself a blind bearing removal tool. This is the only right way to do it. These have an assortment of expanding vises. You simply insert the tool in the bearing, tighten the collar, and attach the slide hammer handle - most come right out in a few pulls. Even the worst, neglected, rusted and crusted ones come out with a few pulls.

I've seen them a lot cheaper, but this will give you an idea of what you're looking for -

Thanks for the help.  Used the heat gun and warmed up the hub for 15 minutes and one of the bearings started to move when I hit it with the steel punch.  I was able to move the distance collar over a bit and get a better shot at the bearings and drove 'em out. 

Thanks again,
Mike
