modela axle keyway

[32forddump]

Are there different width keyways on the axles? Im swapping rear ends and noticed key was too narrow for key way.

Some keyways have been worn wider from running the taper with oil on it, or the nut not tight enough.

Are you refering to a model a or aa?

[32forddump]

model a . What should I do, install the key and make sure nut is tight? Check for play?

The old timers would just close it up a bit with a hammer. I think that was common practice. We did it last summer, but we had the axle out of the car. Worked great. Just back it up and pound on it.

If it isn't too bad, I would be sure the taper is clean, dry, and smooth, then properly tighten the nut and drive the car.

Been out of the Model A restorations for a while now. Does anyone still offer "step keys?" Wider at the bottom to fit oversize axle keyways and standard size to fit the drums.

A good machine shop could make some from key stock and a vertical mill.

I have closed in around the key by using a "c" clamp to hold the key to the bottom of the key slot.

Then use a fairly large pin punch, perhaps 1/4" and a large hammer and "pein" the shoulder of the axle keyslot. Work to either side to "even-out" and center the key in the slot. Start at the big taper and work your way down to the small. You may want to move the c clamp along too.

Doesn't have to be perfect. And when I go back together, I bathe everything in Green Loctite (DON'T USE RED) and put it together quickly - and to a final 130 ft-lbs. (torque to 90 then to 130 minimum two steps.)

Drive it for a trip to get ice cream and then re-torque to 130.

Drive it a week and then re-torque to 130 - or even to 150.
