Title: Installing Crank
Post by: hughes on January 14, 2006, 11:07:53 AM

Any tips for installing the crank into the cases. I go the crank in the freezer and was thinking about transfering heat into the bearing. What's ya'll thoughts. Crank bearings are already installed into the cases not on the crank.

On my red bike I pressed the bearings on the crank and tapped the crank into the case half with a dead blow plastic hammer. Worked very well, but I am not sure if that was the proper procedure.

Hughes,
  Don't heat the bearing. Just having the crank in the freezer should be enough. Usually they slide in quite easily with a few light taps with a plastic hammer.  I've never encountered one that was a press fit.  Normally the effort is to get the bearing into the case. Cam.

freeze bearings and crank.put seals in cases,put bearings in cases,put a little oil on bearings,make sure trans shift thru gears and washers are in place.with everything back to say room temp,take crank out of freezer and slide in.warm left side case while adding sealer to right side and slip into place.button her up while checking crank and sprocket shaft for ease of movement.drop a little oil  onto bottom rod bearing and go to it.

Thanks for the tips. The crank was in the freezer over nite and it went right in with out any heat on the bearings. Could have not been easier. Thanks.
