  • 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.

            Model A 3/4 floating rear axles with a taper axle and hub
            by Rob Doe
            Yesterday, a friend of mine and I were talking about the Model A rear axles and hubs. He was under the opinion that the large key and key way takes the torque loads at the driven wheels. I thought otherwise and said so, but he was pretty sure and is generally more knowledgeable than I am. I thought I learned here on the VFF that the high torque and tapered axle and hub provided the ability to handle...

            Axle key orientation
            by wrndln
            This is probably been posted before, but I have a hard time searching for things. Anyway, I am trying to find the proper way axle keys are installed in the axle slot. I put one in one axle and took a picture of it. The key has a slight taper on one end as shown on the left side in the picture near the threaded part of the axle. Is this the right way to install it or some other way? I would appreciate...

            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...

            I have no key for my electrolock ignition switch, but I have a key machine and blanks. What are the chances of making my own key (how to go about it would be a handy bit of info)or can someone make one for me ? Thanks, Pat...

            Why a Star on the Driveshaft Key?
            by Tom Wesenberg
            My driveshaft key has a FORD script on each end, and a star in the center of the key.
            Does anyone know the significance of the star? Thanks

            Rear Axle / Shims
            by Rob Doe
            Little Bug seems to require a single shim on her right rear axle. My question this morning is:

            Where is the wear? Is the wear on the axle, the hub or both?

            It has occurred to me that a new hub might defer the axle replacement. There doesn't seem to be any leaking of fluids. The axle is pretty rough and the key way is worn, but with one shim and 75lbs of torque all seems...
