Plus Gas for rusty nut syndrome
Hi
I have a lot of small jobs I want to do on my 90 but most of them seem to be involve rusty nut syndrome and they are mostly totally seized!
I have brought some plus gas in the vain hope it might help.
Do I need to put it on over a prolonged period for it to do any good?

Failing that I guess heat might help?
Do I need a big torch and cannisters or can I used a blow torch type affair?

Thanks

I always leave to soak for a while, if it doesn't work I have also found brake fluid can work very well if left to soak into rusty nuts and bolts. Heat source I have a plumbers gas torch that uses the yellow gas canisters, I bought the torch head and bottle from B&Q for around £100 (purchased the best one) and it works a treat it's self lights so no faffing with lighters etc. 90 wolf - Jasmin http://www.defender2.net/forum/topic39408.html

Plus Gas works for me.

Although I usually find with the smaller nuts and bolts that are very rusty once you apply some force to the nut with a socket or spanner the bolt usually snaps anyway which makes removal easy, just make sure you have some spare nuts and bolts handy, preferably stainless ones and apply some copper slip so the next time you wish to undo them it will be a doddle. For those who like Welsh Mountains and narrow boats have a look at my videos and photos at..

A dam good scrubbing of the bare threads with a wire brush will also help.

I think the torch Mash refers to is a Rothenberger brazing torch. And yes, they are great too Thumbs Up

Plus gas wow that brings back memories and the smell. I must have used gallons if it when I was an apprentice fitter at ICI. I didn't know it was still produced, mind I have been out of the business for 45 years, I must look out for some ,I always thought that it was the next best thing to a gas axe for getting rusted bolt and nuts apart. Don't make old people mad.
We don't like being old in the first place,
so it doesn't take much to Censored us off.

Be careful with using flames to heat - there's lots of flammable bits about especially underneath a Defender with the underseal and inevitable oil leaks.

Maybe invest in an impact gun before spending money on flame kits.

If it's to be believed this machine can loosen a bolt tightened to a torque of 1,600 Nm.
