The first time that I ever removed those large axle nut. A big truck service center had messed with them for the PO. Got the cotter key out. Ended up using a big 3/4" drive ratchet. Put a 6 ft pipe over the ratchet. Put me at 195 lbs. Standing on the end of the pipe. Next I had to jump on that pipe to get each nut loose. I didn't reuse the axles, or nuts. How did they get them that tight. And how did the axle, and nut take that? Bob Dunahugh 78 Royale.

Sounds about right. I have broken two 1/2" breaker bars trying to loosen
that nut.

The last one of those I worked on, my daughter set up a 3/4" breaker bar with a 5 feet cheater extension pipe. At 120 pounds she could not break them loose. I had to jump on it with my 200 pounds to get them loose.
A side note.
I do not like putting all of that torque on the trans parking pawl. So when we do it, I have someone inside on the brakes while the other person jumps on the cheater.

Bob,
When I let my compressor turn off at 150psi, my good CP air impact will probably get them that tight.
If you run the numbers on the nut and knuckle stub, the load it can take is WAY UP THERE. (That means he forgot what he did figure out years ago.)
The book says something like: Twist it to X-lbft and then go to the next place you can get the cotter in. Well, if you just missed one, that means you need another 27° and that may be a lot.

A lot of that is caused by idiots with 3/4 " air ratchets. Mine will easily
do 500 foot pounds. On several occasions, it had to struggle to remove
those nuts someone else tightened.

| [GMCnet] New plastic gas tanks needed [message #336686 is a reply to message #336683] |

We have a perfectly good 1973 GMC we rebuilt to perfection... 10 years ago... We made it mechanically sound. I removed and coated both rusted gas tanks. That lasted a few years. Now they leak again. If I fill them, the engine runs fine but then leaks all over.
It is a dang shame to have a good GMC motorhome sitting in the barn not able to even be driven into town.
Does anyone have a source yet of reasonable priced replacement bolt in tanks? $ 500.00 is not reasonable. Plastic preferred?

I have a couple of pristine Cinnabar gas tanks, but like you say, they're
not cheap. $1k for the set and they're not cheap to ship either.
