Not quite on par with Zap.

admin

But I gave it a shot and I think it will work.A buddie at work has been rebuilding a 86 Honda ATV, every bearing in the front differential was toast. Could not locate this little pinion bearing anywhere. The one we DID find had the correct OD and thickness but the ID was too large. So What Would Zap Do? Weld it up and turn it down Just clean up pass.Forgot to get a pic of the weld before I started turning. I layed on 3 light passes letting it cool a bit between each one.TurningAnd it fits. Nice and snug not a press fit. If you cant fix it with a hammer, it must be an electrical problem."Boy, everyone starts with a full bag of luck and an empty bag of experience.

Reply:You used the wrong dial calipers. Zap! uses Chinese calipers, not American. Looks good.kidtigger24  They think I’m crazy, but I know better. It is not I who am crazy. It is I who am MAD!

Reply:Thanks, but dont worry about it.  I doubt id bother to do all that.  Ill put it back like i took it apart, hit it with a chisel round an round
Reply:plumbing sockets:Had to rebuild a Kawasaki diff that somebody had used too long of a helicoil in, which got broken off and trashed the bearings.

Reply:Originally Posted by zapsterAll that would do is turn into a nightmare when the turning part of our program started..If I knew exactly what you were doing Larp by the P/M'S I would have told ya to turn the surface down about 1/4" and shrink a sleeve on it and that way you would keep the welding to a minimum...I did not know you have a lathe at your disposal..All you would have needed to weld would have been the very end just to keep it in place..But it's done now so lets see how long it lasts..I'm guessing a VERY long time.....zap!
