I had that hapen 2 weeks ago. Used heat, 3/4 impact ir gun compressor set at 250, nothing worked. Carefully cut the nut with a dremil after I removed the axle and hub to put in a vice. Used wd40, pb blaster, zep45 nothing worked
So impact gun made quick work of nut, got all new studs in my next question is I have it tight w socket and shear pin lines up...do I Need to try and impact it on another 1/8 turn or is it tight enough? It's a pain lining up shear pin hole ...
Dam! Ya my neighbors daughter lost a wheel on her grizzly lol it rolled down a cliff it was fun getting it back. Nut just seemed to fall off today lol after all the lube....I'll crank it down tomorrow ...got a list of crap to do to wheeler just chilly and don't feel like heating up garadge till weekend
I remember trying to get one of those things off on my front wheel... Tried the heat, impact, lube, nothing seemed to work. I broke 2 Craftsman ratchets with a 4 foot pipe, still didn't budge. Ended up taking a pipe wrench to it with a 6 foot pipe and put my 260lb self on the end and bounced like mad, finally broke loose....
After that I figured my rear bearings could go a little longer lol.
To bad you didn't live closer I got a torque wrench just for that job. LOL!! I had to have a buddy hold the other side down while I tightened those axle nuts. Make sure you use the same size cotter key. Here some pics of what the smaller ones do if the torque aint right. LOL!! The dealer's mechanic did this.
Those are pics of the one that didn't let go. One of the wheels on my Cat came off after they did some work on mine and cost me close to $650 to fix all that got damaged. The torque setting is pretty important.
Ya glad I impacted it and didn't leave it at 140... Just talked to my buddy who works at cat dealer and he says they just impact them on not at 200 though....man I think I'm scared to let dealer do any work
they are always a pain, NEVER LOCTITE them or threadlock them, so long as you hit the torque your laughing they'll stay, I just returned a friends compressor and impact had to wind compressor to 120psi, and give it the guts to get the castle nut off, I've got 1 more wheel bearing to pile up before I've replaced them all... oie.... I'm going to buy an impact just for the job because I can never get my brakes to hold, and keep my wheels from turning with it in 4 low brakes locked when I bounce on my 2ft breaker bar (250lbs) impact makes quick work of it.
