Fun in a trailer!

Hi folks,
it's that time of year, actually a bit later than I would have liked, when the bearings need replacing. Slight problem, I can't get the hub off the axle!

I've removed the split pin and castellated nut, but I can't pull the hub assumbly off the axle. I've tried applying some heat to it but with no result. I was hoping to get the job finished to day, Any ideas?

Cheers guys,
Tim

I don't have an oxy torch, I've been using a 2kW heat gun though and cannot get it to shift. I'm beginning to think I might mave to remove the whole assembly and replace it.

Is it moving slightly? Put the wheel back on that will give you loads of purchase most likely the brake shoes are sticking to the hub. This little trick I learned from my father who was a mechanic for 40yrs. Only one problem with this you usually pull the shoes of too, but they will most likely be shot anyway.
Oops just looked at post again little rib, little trailer so no brakes!!

Yes Alan - no brakes!
It's the bearings which are stuck on the axle stub.

Can you rest it on an axle stand so you can give it a good hit on the opposite side from the stand? That may be enough to shock it, then it might move. If not its down to the pullers and sunday morning.

Yeh, it's on an axle stand and I've whacked it loads from behind. The trouble I've had with pullers is that last time I used them, they basically drilled a hole down the middle of the axle stub!

Don't bother with a 2kw heat gun. Use a blowtorch to heat it then cool with penetrating fluid (fire extinguisher on standby!) Do that a few times-each time will get more fluid in there.

go to a decent hire shop and hire a slide hammer for pulling hubs and half shafts out . It will bolt on the outside using the wheel nuts .
It may leave the siezed bearing centre on the shaft but that can then be cut off easily .
