Ok so I just removed the rear hub and part of the old bearing casing is stuck on the stub axle. I have tried to tap a screwdriver and a gasket scraper behind it, soaked it in penetrating fluid and have not really got anywhere. I have no welding gear or heat, I do not own a bearing puller so would have to buy this but do have a dermal but it is tight on to cut.Any guidance would be great? I don't want to spend lots of money and need to consider the best option here.

 

New radius arm? 

Cut it off?

Buy a puller?

Remove the arm and take it to a garage perhaps?

 

I would really welcome any advice here.

Matt

You should be able to save the Arm for sure.

 

Try heating the race, but don't get it super hot (changing colour), just warm it basically. You can also try to split it with a decent chisel, but wear a full face safety sheild if you do. The race is hard and could well shatter in a big way. Also be careful that you don't damage the boss that the seal runs on doing this.

 

You can get a puller, but you'll likely need a split type, similar to this;-

 

 

although that's a hydraulic type, a screw type will also get the job done. The 2 and 3 leg types ate also good, but there's nothing on a race like yours for the legs to get a grip on until it moves about 1/2", by which time, it'll probably come off!

 

Once it's off, check and clean the stub of any ridges. The bearing should be a neat, slip on fit.

I have used my 3 leg puller with success its only a quick tug usually, used a cable tie atound the legs to help give it a bit of purchase

if you are very careful with an angel grinder you can slit them then use a pri-bar to ease them off

 

thats what we do in the garages anyway.

or get the angle grinder out which is what i always did. and grind a flat on one side.

 

and if it does go tits up you can just press the stub axle out and fit a new one.

I was about to post this question yesterday for exactly the same thing! But after about half hour i got it off! I first heat the bearing up with a blow torch whilst pouring water on the axel to keep it cooler than the bearing, then i put a little grease on the axel, it melted and went down to the gap between the bearing and axel, then i got a thin screwdriver and hammered it in to start it off so there was a gap between the bearing and backplate, then i got a crow bar between and just kept hitting the bearing up and the bearing slowly started to move, when it got harder to move again i just repeated them steps of heating the bearing up and cooling the axel, and LOTS of grease! Hope that helped! Thats how i got it off just yesterday!

For DIY, at home, limited tool situations I have always done what MiniMadrt and Nick suggested above.  I use a thin cut off wheel in a grinder to cut slots on opposing sides of the stuck race.  Use a small diameter cutting wheel so you can get in close without touching the stub axle.  When you have made two decent depth cuts, use a cold chisel and heavy hammer to split the inner race.

Thanks for the advice guys, I used a Dremel with a reinforced cutting disk. I made a small cut in it then tapped a small sharp chisel in and it split in two. Really simple and 2 minute fix. No damage to shaft either.

Good job that's the way I have done it for years. It's some times better and easyer doing some jobs old school rather than with modern tools which some times are well over thought.

Good luck
