Rear axle bearings and seals.

I need knew rear seals and axle bearings.

It's easy enough to remove the axle shafts but has anyone DIY'd the shrunk on collar that holds the bearing and one of the seals in place?

Any tricks, hints?

Will an oxy torch heat it enough to remove it?

Does it need to be drilled and spit with a cold chisel?

Are the collars easy to find?

I hate out sourcing stuff. But I will if I have to. :roll:

You can heat one spot on the collar to a red hot and hit it with a hammer to expand it. The best way is to drill a hole through it and break it with a chisel. To install the new collar have the axle standing straight up and heat the new collar to about 600 degrees F and drop it on the axle and make sure the bearing is all the way down on the axle first.

I replaced one seal and collar on my TO30 and it was a lot easier than I expected it to be. Removal of the collar involved drilling with a bit just smaller than the thickness of the collar so I used an 1/8th inch bit first then a 1/4 inch next and finished with a run-of-the-mill cold chisel. Reassembling requires making a tool to drive the heated collar on the axle. I used a piece of pipe about the same outside diameter as the collar and longer than the axle so I could whack it on the end with a hammer if needed. It wasn't needed though, the impact of the pipe was enough to drive it home. I heated the collar with a propane torch which was more than enough. Since the collar needs to be heated to only about 250F you could heat it in the cookstove oven if it is nearby but you would probably need to get it to 350F or so to maintain the minimum needed when you transport it. If you heat it with a torch, it is hot enough when water fries a bit when dropped on it. Get the end of your pliers hot also and don't tarry after the collar touches the axle or the collar will cool and the axle will heat and nothing will move. If the axle is resting on the floor or the ground put your lug nuts on the studs to protect the threads.

When you drive the collar on with a pipe, don't use a rusty pipe. Hammer seems to shake the rust loose.
Collars are real easy to find. I split the old collar with chisel, sometimes bearings will just about slide off and sometimes you have to cut bearings off.

i put the axle in the freezer and collar in frying pan. Don't remember temp I measured collar at. Stand up frozen axle and make sure bearing is seated all the way. Collar will drop right on. No pounding needed.
