Seized on wheel nuts

[James 6920]

Evening all, got a flat Lorry trailer with commercial axles in the workshop that I want to service hubs brakes etc, but I can not budge the wheel nuts!! Big impacter, bars etc won't touch em. Mate of mine suggested letting the tyre right down and heating up the nuts with oxy but I'm just a bit concerned about this, he did say use a little plumbers gas torch to heat em as well if oxy was to fierce. I'm still not convinced it's a great idea anyone got any suggestions. TIA.

Are you sure they are seized or are they opposite thread and you are actually tightening them

 

[James 6920]

Yes there right hand thread, I've managed to loosen four but the rest are having none of it!!!

Done this, it knackered my torque multiplier as well.

Torque multiplier is the best tool, get a £30 one off eBay.

It's not often the gas axe is defeated! Get the cutter out & real fierce heat the offending nut for a short period. Presto the bl**dy thing will come undone!

If you're wanting to take the hubs off anyway, then just undo the hub nut and remove in one lump. F'ing heavy though

Unless you take the whole lot off at the wheel bearing?

torque multiplier but watch you don't snap them or a big nut gun soak them really well overnight even only heat if its the very last resort as you will weaken the studs and nuts especially if its on an hgv

Just concerned about the tyre exploding or something like that!!!

 

[Mursal]

But they will be fine, if you heat quick and hit with the gun. Let them cool in the air .....

if you do use heat let the air out

 

[Mursal]

Tyre wont explode, but let it down if you want ...........

Warm them up,,Inch drive impact socket,T bar and 6ft of tube

Heat. Then cool. Fast till they stop fizzing. Best way. Then do again. Then inch drive t bar on impact socket and have made an adjustable support to go under extension Then long pipe with eye on top. Then short bit of Strap to tele boom. Pull boom in it either gives or shears. If it gives then inch drive windy usually takes them , any sheared. Just take hub off punch out sheared stud and put new in. Don't be frightened of giving it heat. Do you have a pepper pot. To go on gas. But if just doing brakes take hub and wheels of in one unit

Heat nut red hot, crack it then let it cool while moving to the next.

If too hot threads can pick up when undoing.

May need to heat more than once if a real pain.

just get a big bar and give it a tweak with the telehandler if muscle power isn't enough. if it shears do as above.

Some say I can be a bit heavy handed in similar situations

I wouldn't do any heating work on a tyre on the rim. Its not worth the candle. Even if you let the air out, the bead will be sealed and if a pyrolosis reaction starts it will expand the air in the tyre faster than it could possibly get out of the valve.

Iv often welded tractor wheel centres where they crack between the studs, il be taking tyre off next time!

Heating the nuts red hot and cooling super fast will shake the rust. Usually best throwing the part in a bucket of water tho for top results but a good flowing hose will do as well.

Leave the valve core out
