richard-b61 Posted February 11, 2014 Share Posted February 11, 2014 For all of you guys who have pulled an old rusty Mack out of the field that has been sitting and rusting for years. What is the best way to remove the rusty lug nuts that haven't been taken off the truck in Years? I can probably get them off, but I figure why not ask someone who has done it before and save myself a little time and grief. Thanks Quote Link to comment Share on other sites More sharing options...
KECorbin22 Posted February 11, 2014 Share Posted February 11, 2014 Wire brush, PB Blaster, More PB Blaster and some more PB Blaster. Quote Link to comment Share on other sites More sharing options...
Maddog13407 Posted February 11, 2014 Share Posted February 11, 2014 spray some pb blaster on them. let them soak for a few days. they are coarse thread so they usually come right off. don't take the back ones all the way off without knockin the wedges loose first tho!

TozziWelding Posted February 11, 2014 Share Posted February 11, 2014 Kroil and time, if that dosen't heat them up with a torch and touch a candle or bit of wax to the threads and they should come right off. 1 Quote Link to comment Share on other sites More sharing options...
Superdog Posted February 11, 2014 Share Posted February 11, 2014 The ones that will give you the most grief are the ones on the lighter 6 spoke tandem axle drive wheel hub that the studs were held in place with a cotter pin,if they start spinning on you.might as well get the torch.

thomastractorsvc Posted February 11, 2014 Share Posted February 11, 2014 a good 3/4 impact wrench Quote Robert"I reject your reality and substitute my own." Link to comment Share on other sites More sharing options...
Bobby Covert Posted February 12, 2014 Share Posted February 12, 2014 I have removed rusted bolts with PB blaster, mep gas torch and believe it or not Coca-cola Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted February 12, 2014 Share Posted February 12, 2014 Use that koil and let it set about 3 days and go back out and look. Don't be surprised that they came off by their self. Quote glenn akers Link to comment Share on other sites More sharing options...
gearhead204 Posted February 12, 2014 Share Posted February 12, 2014 also a air chisel with a blunt tip and drum on the flats of the nut or top of a bolt while using blaster or kroil I use this quite often on old farm equipment with good results Quote Link to comment Share on other sites More sharing options...
Maddog13407 Posted February 12, 2014 Share Posted February 12, 2014 usually a 3/4 impact gun will snap the studs right off and make more work for you. I have used PB blaster on exhaust manifold bolts before that wouldn t budge, came back three days later and screwed them off by hand. amazing stuff, has some kind of catalyst in it to eat at the rust.

thomastractorsvc Posted February 12, 2014 Share Posted February 12, 2014 actually an impact will break them loose with or without soaking them in your favorite "spirits", if you want to break them, use hand tools and a cheater extension. 99% of the time a 3/4" impact or a powerhouse 1/2" impact will pull the lug nut off or lug nut and stud.

eddeere Posted February 12, 2014 Share Posted February 12, 2014 I have used an impact turned down with PB blaster. You have to hold the impact on the nut for a while and let it vibrate. The vibration and BP plaster have worked for me on a lot of farm equipment, but it takes some time. Quote Link to comment Share on other sites More sharing options...
Quickfarms Posted February 13, 2014 Share Posted February 13, 2014 Take your time and keep spraying it with your favorite snake oil, wire brush the surface rust off. When it comes time to remove the nut if there is a lot of thread exposed you can clean up the threads with a die. The big thing to remember is loosen the nut up until it stops moving then screw it back on and clean up the threads and repeat. Quote Link to comment Share on other sites More sharing options...
