Stuck bearings

It seems to be the day for things gettin stuck!

I'm trying to change the bearings on my trailer (unbraked) for the first time. I've not had the boat long, and decided that as a winter treat, I'd overhaul the trailer (which was secondhand) including new bearings.

Part of the inner bearing is stuck on the axle. The bearing has actually separated, leaving just it's outer casing firmly attached to the axle. It's the bit in the red box in the pictures. You can see the replacement bearings on the floor next to the axle, on the picture without the bricks!

I've tried hitting it from behind, all round. I've tried WD40. I've tried a kind of corkscrew gadget to drag it off. I've even tried to hacksaw through it.

I'm beginning to wish I'd just paid the guy £70 to do it for me!
Any thoughts/ideas would be gratefully received.

Thanks,
Tim.

Bearings

First of all clean shaft up so its easier to get off when it does release.
Put a 3 leg puller on it.
If it dont shift put some heat on it then try again with pullers
It will give,rarely do we have to grind them off

I had to grind one of last year for the brother in law.
Gently does it with a small angle grinder. Two separate grinds is best making sure you donít grind the shaft if at all possible . It should then "ping" off with a sharp rap from the hammer & chisel. Dont forget your goggles!

Yep.... use the thinnest cutting disc you can as well-I get mine from a welding suppliers and they are only about 2mm thick. That way if you do inadvertently grind the shaft it limits the damage. The thin ones cut much cleaner too.

I'd heat it up (the bearing), It should expend and come off with little problem, if you can.

See its not just me...

Seems heat is the wonder cure all at the moment. Personally I would gring it off, done it before, would do it again.

I have had reason to reach for the cheese wrench (Stillson) to remove seized inner bearing races. Once you get it turning, it should pop off with a bit of gentle persuasion from a hammer and punch from behind (or a three legged puller if you want to be posh!)

hi
had the same prob many times, a good sharp chisel will split the old race to make it easy to get off .

Get out the angle grinder and be done with it. Five minutes work, max.
