  • Rear Axle key install / orientation

    can someone refresh me the correct factory installed position of the axle key in the key way, orientation of the beveled tip ?

  • #2
    The bevel goes down and inboard.
    There is a corresponding bevel to the axle groove that has been machined.

    I like to only put the key on part way, install the hub, and then with a small screwdriver and hammer, I tap the key home until it is flush with the outboard edge of the hub.

    There have been cases where the key was put in too far, and the hub over-tightened trying to get the hub to seat, and then cracked because of this oversight.

    Remember, the key is only a locating device, and intended to keep the hub from spinning while tightening the nut. It is the taper that provides the surface area for grip.

    These 5/8 nuts would have been better off as 3/4 nuts. Be careful, the threads strip easily if you over torque

            In addition I have seen axle keys sold by vendors that are only cut off square stock and are not hard like the originals.

              I got one of those recently. It was in a kit with new nuts, washers, packing seal, and cotters. Disappointed when I saw that.

            Rear axle key question
            by Mickey
            I know the beveled end of the key goes inward towards the bearing but does the bevel itself go down into the groove up?

            Axle shims
            by carolinamudwalker
            When adding rear axle shims do you lubricate the hub with anything to help it torque up easier? It is hard to get the hub on without getting grease on the axle anyway. Maybe liquid soap!

            Rear axle taper
            by Aretino
            When assembling the rear wheel hub to the axle taper is it installed dry or lubed?

            Probably my ebrake?
            by Beauford
            So putting on the rear drums, one side slide right on and fits nice. The pass rear not so much. I have ebrake released and brakes in and I still can't get drum to seal to backing plate. I have checked the key placement, and moved it around different ways for giggles. I can't recall if it was like this before and I probably did not realize at that time the correct fit. I was just happy it was on and...

            AA worm drive hub
            by pAAt
            On my worm drive, I pulled the rear hubs off to check brakes and found castellated nut loose with no cotter pin. Looked like it was also missing a washer to make nut workable. My question is, is this hub a snug fit on the tapered shaft of the axle like the Model A hub ? I've made a washer that fits, but was wondering about tightening this thing up tightly. Thanks, Pat

            Won't Go Into Gear
            by MatthewO
            I have come a long was with my 1930 Ford Model A pickup so far but now I face a different issue. My Model A will not go into gear. I had tested every gear, putting the clutch in, shifting, and then taking the clutch all the way out and the vehicle didn't react. I could however feel as if something was trying to grind inside the transmission. To give a little background this is the first car I have...

            Hub to Hub axle measurement?
            by Corley
            Anyone know the "wheel mounting surface" to "wheel mounting surface" on a model A tudor rear axle, and is it the same for all years (28-31, I think yes). Not looking for the track width, that is something different. Of course I can measure it, but that is difficult without removing the wheels, and the word "lazy" enters my thinking on that. (I'm thinking with a 56"...
