9934059 Posted August 24, 2003 Posted August 24, 2003 In trying to remove the hub from the left rear of my Landlord, I broke the set screws off inside the hub. Tried using penetrating oil and heat so that "easy outs" or extractors could be used to remove the broken screws. This failed so I chose to drill 'em out!!! I drilled through the key stock and the key way and also drilled into the shaft trying to ream out the broken screw. What options do I have regarding repair? I think that I drilled into the shaft in both places between 1/8" to 1/4". Thanks for any help!!! Smokey
MPH Posted August 25, 2003 Posted August 25, 2003 Sounds like all you need to do now is retap your drilled out holes, put in a new key, and your good to go. Oh, do whatever repair you were set out to do when you went to remove the hub to star with.MPH
ReedS Posted August 25, 2003 Posted August 25, 2003 The axle shaft has a counter-sunk spot for the set screw (the one on the shaft not on the key)anyway so an extra 3/16" won't hurt it and as for the set screw at the key I'd replace the key and file any burrs and it should be good to go. And as Marty said don't forget to retap the hub! Good luck!
torinwalker Posted August 26, 2003 Posted August 26, 2003 Repairing any damage to the shaft (i.e. Removing metal from where metal shouldn't have been removed) is not such a terrifying thing. What you need to do is find yourself someone who welds. Choose the appropriate metal filler (mild steel) and fill in the holes, keyway, etc., where the steel is missing and grind, sand, hone to finish. If the guy is good, you shouldn't even see where the defect was without potassium chlorate (helps visualize weldment cross sections by showing the grain of the metal) If you ruined a keyway, you can probably reshape the keyway with a hardened chisel and a lot of patience. BTW, the same goes for screwing up tapped holes. If you strip a screw and rethread the hole, then strip it again (arrrg!) you can, providing it's not too deep, bevel the hole, fill it in, then re-drill and re-tap the hole with the original size. Good MIG welders can shoot the wire to the bottom of the hole and spurtitively fill the blind hole until no more hole exists, then rebuilt as normal. Quite frankly, if you haven't tried welding, perhaps now is a good time to learn. Welders can be rented from Home Depot for very little $$, plus, they're a blast. MIGs are point and shoot, very easy. (Still, good idea to read a book first...) Torin...
