Topic: 1936 Ford Rear Axle nut torque setting?

  Would anybody know the rear axle nut torque wrench foot lbs. setting for 1936 Ford Sedan?

  start at 200 ft/Lb and tighten to the nearest opening for the cotter pin. Do not use lubricant on the threads. Recheck after driving.

  The axle taper and hub needs to be dry and free of burrs also. Scribe a line on the end of the axle to indicate the orientation of the cotter key hole. That makes it easier to locate the castle nut correctly.

  The rear axel nut torque has come up in pervious threads/discussions but no one has yet to verify with or produce official Ford ducumentation as to how many ft/lb it should be. I'm thinking that it may be found in Model T or Model A documentation.

  I tighten mine with an air wrench set at 250 ft lbs, and have never had a problem. Just recheck them after a hundred miles or so in case the hub has moved on the taper. We clean the axle, axle threads, and hub with brake cleaner to be sure all are as clean as we can get them before assembly and tightening.

  MG,

On April 19 I posted the following in response to your same question on this subject:

MG,

In the September/October V-8 Times, pages 44-50, then Associate Editor Rusty Davis (currently Chairman of the Judging Standards Committee) published an article about the evolution from 1946 – 1947 models. The article included a number of Ford service letters and “mailgrams” gleaned from the Ford Archives.

A mailgram dated 10-20-47 detailed the procedure for assembling the hub and drum to the axle shaft. It specified use of a 24 inch handle and a torque of 300-350 foot-pounds. Service Letter A-25 dated 11-6-47 corrected the torque setting, stating: “…tighten nut 356074-S to 200-220 foot pounds; then continue to the next castellation providing final resultant torque does not exceed 275 foot pounds.”

  1947??? I wonder what documentation the guys used back in '36?

  When I was a mechanic at a Ford dealer in the late forties to mid fifties, we never saw a torque wrench, or specs beyond those involving engine reassembly. The company held regular service meetings to teach how to tighten head nuts, spark plugs, etc, with ordinary hand tools, such as a long T bar handled extension for the heads. Today, torque specs, including the " torque to give" fasteners are universal, and must be observed. The difference was likely that old cars, particularly Fords, were heavily over engineered. Henry Ford had little use for anything more exotic than gauge blocks to set manufacturing standards. It resulted in the survival of the vast numbers of his cars that we have today. Expansion of attention to fine points doesn't seem to have given modern vehicles much of an advantage in that respect.

  My Dad was a mechanic at a Ford dealer in 1932 and his advice to me about this subject,tongue in cheek, was"tighten the nut as tight as you can get it then go one more round". I have his tool box and some of the tools he used at that time and one tool I value most is his set of feeler gauges. It has nine gauges that fold up in a handle. On each one is what it is to be used for. The first two are spark plug and etched in the first one is "SPK 35 PLUG A" and the second is "SPK 25 PLUG B&V8". The others are go-no go for "VALVE and DIST". On the handle is stamped TRUTH TOOL CO MANKATO MINN. It still has some 1932 grease on it LOL !!

  Jerry, I can identify with your feelings about your Father's tools. My Father was a Machinist, and I have not only his tools, but his 6' tall personal locker, which still contains personal items from his 35 year career. Every man should have the ability to take a glance into the past, and I'm one of the lucky ones to be able to take that glance while doing the things I enjoy best.
