    Hub seal adapter

    When it comes to older equipment such as my Taylor 23,000 lb forklift many things are either no longer available or require special ordering at exorbitant prices. When ever possible I won't play their game.

    Such is the case with the hub seal for the planetary drive axle. I found the correct seals for $200.00 apiece but they were a 12 week delivery, Yeah RIGHT! Not going to happen in Frank's world.
    The only thing really important is the inside diameter being correct for the spindle the height and OD can be delt with providing the OD happens to be smaller than the original.
    So here is what I did I researched for double lip seals of the correct ID and came up with a pair for $15.00 apeice + $5.00 shipping It was immediately a no brainer as to what I would do next. What I needed was a cylinder with a small enough ID and a large enough OD to machine an adapter from. The only thing was I didn't have one. Next venture was to find something I could increase or reduce in size to make the adapters out of
    I found this

    After cutting it open this was what I had to work with

    Needs to be about 1/2" smaller ID so I can machine it out to fit the new seal

    First cut was not going to be enough so cut it a second time

    Now to reduce the OD by clamping it down in size It is going to be close needs thicker wall thickness but it is what I have to work with hopefully I can make it cylindrical enough to require minimal machining

    The OD is very close as well

    After tack welding I ground a deep grove on the inside to weld first since it is easier to grind the outside to the root weld than welding the outside first and doing it vice versa
    Hub seal adapter-img_20220611_144740hs.jpg
    Now the groove in the outside ground all the way into the inside weld

    the Weld

    Looks round enough or as close as it is going to get If I don't get full clean up I'll epoxy the void
    Hub seal adapter-img_20220611_163315hs.jpg
    It is really going to be close but crossing fingers
    Hub seal adapter-img_20220611_163328hs.jpg
    ID done doing the OD

    Now machining the opposite end for the bearing clearance

    Seal and adapter installed just a very small amount of Devon plastic steel epoxy to fill a couple small voids and insure a good tight fit

    Great idea. Also, thanks for the picture line-up rather than a long, time-wasting video.

    If folks are looking for videos, I'm not the one, Or the way a guy who used to work for me put it "I ain't the one" Even though I more often than not stray from the purest vernacular with my explanations and don't always get straight to the point. I much prefer pictures and explanations.

    Very nice fix. I have delt with axle and transmission seals and shafts for 55 years. I laugh when a parts guy says it can't be done. Good stuff. Mr Mikey.
