  • Rear Hub bearing, seal and axle key information

    Original Thread:
    https://www.vintagefordforum.com/for...ll-orientation



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

    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

        YES, beveled in & down. I leave the key out a little, over the threads. I also put a little "ding" on the sides of the keyway to keep the key in place, when I tap it down. After sliding the drum on, tap the key in flush.

          Rear Hub Seal Info!

          I'm installing rear wheel hub seals right now and I have a question. I searched the Chassis and Powertrain tech areas, but no luck. Maybe I'm too stupid to do an efficient search??

          How deep do the seals sit?
          Seams simple enough... most cars have a ridge to seat the seal against, but not in this case. This makes for no hard stop for the seal and I'm concerned that I'll install the seal crocked or jam it up against the bearing.

          Maybe I could place three spacers between the seal and the bearing, then remove the spacers when the seal is seated. What are you guys doing to make sure its straight? If the seal is crooked it will wear prematurely.

            Seat it just far enough to get the seal retainer in the groove.

            That doesn't assure that the seal is straight, since I cant pull the seal back up without damaging it.

            Thanks Mitch, I was unaware of this tool. This is the solution of course. Since my seals are already in, I'll have to set them evenly another way this time...

        • #6
          • This is a good tool to have. It perfectly seats the seal just below the snap ring groove. If you go down to far the bearing can rub the seal
            It's better than using a socket or a block of wood etc. I always pack the spring groove on the seal with grease so it does not pop out on install
            If using an alternative method be careful not to dent the seal

            Defective rear hub bearings!

            I found those pictures of how the faulty rear bearings wear before they blow up. Notice how the end race wears down until the pins fall out. The end race is softer metal than the hub so you really wont see any damage to the hub until it grenades. The picture with the side by side bearing shows an unworn one on the right. The unworn bearing has those extra supports in between every two rollers, where as the defective ones do not have any.

                The hub seal opening / spring goes down or away from the snap ring

                  Damaged rear axle keyway!

                  You need to keep the axle taper clean dry and smooth, and keep the axle nut tight to prevent damage like this.
                  I wonder if someone was spinning the rear wheel, then hit dry pavement to do this much damage?
                  This is the second free axle I got with this kind of damage.

                    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...

                    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!

                    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

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

                    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...

                    Key cylinder is seized in the handle
                    by EarlyBert
                    Good day all. I am new to the Model A lifestyle. I recently purchased a 1928 AR Tudor that was, for the most part, restored. One issue I am trying to address is the key cylinder in the passenger door handle is seized in the handle. I made a key for it & the tumblers are free but the plug won't turn.
