Howdy, Boys:

Just put my rear drums back on the '39 and need the torque spec for the axle/drum nut. I am much obliged for the information.

How much do you weigh?

Rebel Sympathy · 02-08-2013, 12:36 PM

I weigh 195 lbs.

Spec copied from the Flathead Ford Techno Website:

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."

Holy Toledo! Well, that's what I needed to know. I don't even know if I'm that strong anymore. Thank you.

The spec is 200 lb-ft. Use a breaker bar and stand on it. Drive it about a mile and tighten again. Then replace the cotter pin. You need to get the taper to lock. The driving torque must go though the taper and NOT the key.

Thanks, men.

Im not looking forward to trying this when the time comes.. size of the nut and the torque needed.. Ohh just waiting for the big "bang!!!" and ohhh shit! . Anyone had it go wrong ??

jkeesey · 02-08-2013, 07:10 PM

Mike I think you made out pretty good. 195 lbs you can stand on the breaker bar, I'm 160 and I've gotta jump on it like a kangaroo.

You want to have the tapers on both the axle and in the hub smooth, clean and dry. Any kind of burrs or nicks or oil or grease could cause problems down the road. Some people use valve grinding compound to lap them to each other. If you do this, be sure to keep it out of the bearings!!

Pete has the answer. Smooth and dry. The long tapper is what drives the car. The key is just a saftey feature. G.M.
