Again, appreciate all the comments from you all. 3 more better pictures attached after further cleaning axle. I do have one of those Blue Point "thread fixer" tools which works like cutting a nut in half, etc. Will use it on the axle. Think John has it right in suggesting the "give it another try" approach & if it doesn't hold--time for a replacement axle (we all know how easy that job is).
I keep wondering about the wisdom of the deceased and long time V-8 Club adviser, Dick Flynn, who wrote many articles on all aspects of V-8s and obviously worked on countless cars, doing everything there is to do on them. His advice on torquing axles (knowing the official Ford guidelines of 200 foot-pounds) was to torque to 150-160 FPs. He claims never to have had a failure doing this. |

This one, not so much. Variance in diameter and thread height. Maybe could work sorta. |
Re: Difficulties installing & torquing rear drum - Help! I wouldn't have a problem with those threads at all. Just be sure your nuts are good!
Mr Dick Flynn has been a puzzlement to me for years. I'm sure he had forgotten more than I ever knew, but I also feel that some of his advice was questionable, which in itself puts a cloud over all his advice. That he professed that Amway products were the ultimate answer to every need was likely a big part of my skepticism, but then, I like Marvel Mystery Oil, so what do I know? |

Re: Difficulties installing & torquing rear drum - Help! I am awaiting the arrival of original used Ford axle nuts before trying again with my little torqueing project. Expect them by the end of the week. Have done a lot of research on the Internet to try to locate any source for a Grade 8 5/8” – 18 slotted nut. I found nobody who carries a Grade 8. Some carry a Grade 5. One supplier told me that this nut is no longer manufactured. This leads me to the conclusion that 5/8”- 18 nuts being sold today by old V-8 Ford parts suppliers are not Grade 8 unless they are very old stock. My obvious conclusion is that the ONLY way to go is to use the original Ford nut—no exceptions. In other words, unless you have the absolute assurance that a non Ford nut is a Grade 8, don’t use it. After I explained that his nut failed, the vendor who sold me the nut that failed is removing them from stock and will no longer sell them. He was appreciative of my letting him know.

Isn't this good enough........?

Re: Difficulties installing & torquing rear drum - Help! The correct Ford rear axle nuts are a specially hardened thick items that are to placed over a correct thick washer. No attempts to chase the threads should be attempted. If the threads are damaged, the axle must be replaced, or it is likely the end will separate and the wheel will fall off on the road. Don't put anything on the axel taper. It must be clean and dry to seat properly. We tighten the nuts with a breaker bar wrench with a pipe extension on the handle. Retighten after running the car around a hundred miles. Here is a good tip: mark the end of axle with a line to show where the cotter hole is with a file. If, after tightening, the hole doesn't line up with the slots in the nut, back off only to the next slot.

I've got an axle with really good threads on the end...well, the other end not shown in the pic.

Re: Difficulties installing & torquing rear drum - Help! Update. Cleaned axle threads a bit using Blue Point tool. Then, using correct 5/8” - 18 good used Ford nuts obtained from unidentified source, was able to torque both rear drums to 175 FPs. As suggested by John (JM 35 Sedan), will drive the car a bit, then add 10 FPs repeating until I reach 200. Thanks again to everybody for your input.

Re: Difficulties installing & torquing rear drum - Help! Sounds like you are off to a flying start! If I recall correctly, the nut you used before with suspect material and heat treat failed at 175 ft lbs.

Re: Difficulties installing & torquing rear drum - Help! Hopefully as you reach the desired figure, you will have a conveniently located slot in the nut to put the pin in. It's a pain if you've just gone past one slot and are almost 60 degrees away from the next.

Re: Difficulties installing & torquing rear drum - Help! Yes, the original nut I used (non Ford--less than Grade 8) failed at 175. & I had a lot of residue from the stripped nut threads to clean off the axle--but seemingly did not cause any damage to axle threads--which makes sense if you think about it. I was careful to make sure my new nut lined up with the cotter pin hole on the axle & only needed to make very minor adjustment. The 60 degree aspect is significant, I agree.

Re: Difficulties installing & torquing rear drum - Help! Wow, Great result!
