Loose bearing.
« on: January 19, 2013, 05:59:03 pm »
Just discovered what looks like a loose main bearing in my crankcase.
What is the solution to properly locate it in the housing?

I have had a set of cases repaired in regards to gearbox bearings. The guy that did the repairs got a new bearing and closed the ends up, then put it in a zinc(?) bath and built up the O.D. he would pull it out periodically and measure till he got the required size. You could machine out and put a sleeve in as well. Specialist stuff thats for sure.

An easier way {although a bit rough} is to centre punch the bearing housing in a couple of places.p
what ! Who me ? Nah

Loctite -  have a product called quick metal ( 660 retaining compound )  used by the mines when shafts are worn - hardens to doudle the strength of a press fit.
Able to fill an  area of .5mm full strength in 2 hours

Thats the silver tube that comes out as a paste rather than liquid? Have 1 of my rear hubs for the CZ done that way

Thanks, I tried the centre punch trick when I assembled it.Guess it didn't work ::)
When I pull it apart I will give the locktite a go ;)
