Bearing not budging
« on: January 25, 2015, 05:36:23 PM »
After finally getting the retainer off (courtesy of a home made tool from a mate) Ive tried to get the rear wheel bearings out for over 2 hours with no success. 
Tried heating the hub to get it to expand a bit, tried pushing it out with an expanding anchor bolt, tried cutting a groove in the inner race to relieve some tension, all with no effect.  Anyone got some tips?

Is the axle collar moving from side to side ?

The axle collar is the shaft that is between the 2 bearings inside the hub.If its free push one end over and get a blunt instrument slide it down onto the edge of the bearing and wack it then move round and hit it again finally pops out well normally for me

If I hit the collar with a punch I can push it over, but even then the bearing won't budge.  I've mushroomed the end of my drift!

Can push it over with a drift.  Front hub moved fine, had the bearings out in 5 minutes... not so much with the rear.

Try the other end but use something solid like a socket set T bar never fails for me then go back to the other side and find something thats more or less the same size like a socket and hit it
Best of luck

More heat needed. You need to get the bearing red. Not sure what you are using for heat ?

A cheap parasene blowtorch.

That is not going to get enough heat. Pop it in the oven at 220c for a hour and make sure all the windows are open and your smoke alarms are of. If it doesn't budge after that, you will need a stronger blow gun.
