Axle-Nut Torque

[Admiral]

Hi all,

Just curious, what's the torque spec for the axle nuts on a 1936 Ford rear-end? I did a search but it wasn't conclusive. Also, aside from going out and getting a really expensive torque wrench how do you guys achieve this figure? It's quite high, isn't it?


Thanks!

Have a 175-200lbs person stand on the end of a 1-foot long breaker bar.

I like this idea! It's brutally simple and very effective.

Here is the spec I usually refer to that was posted on BillB's Flathead Techno Site.....

The 'V8 Times', Sept/Oct 98 Issue, pages 46 and 48, quotes several Ford Service Letters and later corrections.
The final direction on tightening axle nuts reads: "tighten nut 356074-S to 200 to 220 foot pounds; then continue tightening to the next castellation providing final resultant torque does not exceed 275 foot pounds."

I only have a 150 lb torque wrench, I go to that and then to then next castellation using a breaker bar. If anyone can go further than that good luck to you!
Its important that the taper fits well and is clean and dry.

Yes, I know about the taper, in fact I got some valve-grinding compound and lapped each drum to each axle end. I also labeled each drum so they stay on the appropriate side of the vehicle.

I wonder, with so much torque do the threaded portions of the axles ever break off? My car's axle shafts looked A-ok but still, I'd hate to have the end snap and then have to tear the whole rear apart again to replace the shaft, though I guess that's better than losing the wheel while driving, LOL!

OR, you could have a 100 lb. person stand on a two foot wrench... If you weigh any other amount, do the math and mark a position on the wrench on which to put you weight...

Karl: I think your Math is wrong, Wouldn't the 100 lb. person have to stand @ the 1' mark.
You forgot to consider the the person has two feet all ready.
