rear axle torque

[woodie49]

Brakes on the '49 are all back together. I am looking for the torque spec for the axle nut. The manual never really gets around to even saying to put it back on, let alone what to torque it to.

can anyone provide me the spec??

Thanks

My manual dosn't give the torgue either:confused:, but when I did mine I used a 250ftld impact wrench and made them TIGHT:D. If you use a breaker bar, stand on it. don't back off to put the cotter key in, go tighter. If you leave it loose it will beak the key and leave you stranded:eek:.

The Oz 1962 Chrysler Royal workshop manual has a torque spec of 145 ft/lb MIN for the Axle shaft nut, so yep, TIGHT and them some more..........lol........andyd

P-15 shop manual says 142 ft.lbs.

142 ft. lb. is exactly right Niel..page 22 in the service manual, at the page bottom, Axle Shaft Nut..directly under the torque specifications

[Dodgeb4ya]

At 145lbs of torque the cotter key slots always line up on my cars. Never at 142lbs!

I also wondered at the 142 number..and said why not round it off +/-..and what percent of margin is there for all the torque wrenches out there in mechnic's land?

Front axles are tightened just enough that the bearings start to drag when you spin the wheel then backed off to the nearest hole for a cotter pin.

 

Or looking at page 12 in the 1946-54 Plymouth Factory Service Manual:

 

Quote

 

Front Wheel Bearings

To adjust front wheel bearings, remove hub grease cap and cotter pin from the bearing adjusting nut. Rotate wheel and tighten adjusting nut until a slight bind is felt. Back off adjusting nut to the nearest cotter pin slot and install cotter pin. Never back off adjusting nut less that 1/2 the distance from one slot to the next slot. When wheel bearings are properly adjusted, the wheel must rotate freely.

 

Reprints of the factory service manual are available if you can't find an original. Definitely recommend anyone working on a car have a copy of the factory service manual for that car.
