Help! want to get rover on the road tonight!

Alright, i had a wheel bearing go out on me and i put the new one in the hub and when trying to re-assemble i noticed that part of the old bearing was stuck on. I've heated it up, tried to wedge a screw driver between it and i just can't seem to get it off. any ideas?

I think you are going to need a press. If you have a cutting torch you can cut it off without harming the hub, but be careful. Additionally, if you get it off be careful putting the new one on, you can damage it if you beat on it.

I don't think the inner raceway should be on there that tight, but then again you need new bearings for a reason. If you have a cold chisel, don some safety glasses and give it a firm whack, but not too hard or you might distort the spindle. If that fails get out the cutting wheel and a dremel to finish the fine work. Cut the fucker off.

Then heat the new inner race and drop it on. Maybe even throw the spindle in the freezer for an hour or so to shrink it. Makes the two go together easier.

Buy a dremel with minature cut off wheels and a big cold chisel. Get it cut with the cut off wheels (you will use five or six) and then chisel the last little bit to open it up and then it should slide off. Frankly, you might need a new stub axle (or spindle in US speak). You can try just the cold chisel and try to wedge it behind the bearing, but it will probably be rusted/heat-welded onto the stub axle.

Byron,

Curious--you recommend a press. How do you use a press to get that off? I love good tips!

My method is to use a drill. start small and go progressively larger until the part has just a little bit of metal holding it together. Then a sharp hit with a hammer and cold chisel will make it go away.

can't drill the bearing race, they are too hard. maybe if you use a solid carbide drill. Had this happen once, used the grinder method.

Could try it on a press using a bearing splitter but if it is really on there you could break something and that would just not be fun.

FIrst thing I would do is take a look at the seal race, it looks kind of scabious, is it in good enough condition to provide a decent sealing surface? If not, new stub axle is in the cards.

I want to know how he managed to get the hub balanced on the edge of the table like he did. With that sort of talent he should move to Vegas and be a magician.

Couldn't you just put it in a vise (jaws on the race) and then twist the hub to get it to break free?

Not easy to cut or drill.. that shit is hardened... You can always bring it to the local machine shop. I'm sure they can get it off for ya..

The stub is probably ruined from the looks of whats left of that bearing. You already have it off so just call Will Tillery and he will have a good used stub in the mail the same day.

Use a cold chisel (and hammer) behind the back side of the race to wedge it off. Work carefully around the circumference, and be patient. If you get too enthusiastic, you may bugger the spindle.

I blew a wheel bearing on the Maine Turnpike ~1972. Using the method above, I was able to replace the bearing beside the exit ramp. I was packing up my tools when somebody stopped to ask if I needed help.

It's probably easier to do this with the spindle attached to the axle, so you have plenty of mass to work against. I wouldn't want to try it while holding the spindle in a vise.

I think everyone is missing the fact that the race is the piece pressed into the hub, the piece we are looking at in the photo is the bearing which is completely destroyed, the rollers are gone.

Weld a bead around the race protecting the stub, when it is hot the race should expand enough to get it off. Or it's teh angle grinder.
On a regular cup the welding will shrink the cup/race enough after it cools to drop out a stuck cup.

All this assumes that the bit behind the cone where the oil seal rides is in good shape. If not, then it needs to be replaced. On my IIA it is a separate piece, but I seem to recall that it is an integral part of the spindle on the RR. If so, then maybe a new spindle is the solution.

After all of this I would expect that there would be new replacement parts in order when you get home. This is normally considered a "get it home" solution. Not always but considering the heat involved, with the bad bearing not the welding, you shoudl seriously consider replacing the "hot" part.
