non engineer type being confused..
I have been posting lately about my adventures in final drive failures and successes....Thank you Bennett very much for the rebuilt drive! Today I took the old drive and pulled the bearing off the crown gear, prolly shoulda got pictures of that. I put the gear in a metal bowl of ice, and heated the bearing with my propane torch, used a couple of flat bars, and popped that sucker right off. Anyway, enough of the braggadocio (sp?). The reason for my post is that I measured the shims for the bearing, and it looks to me like they are a .2mm and a .9mm. I looked on line at the A&S cycles BMW OEM catalog, and the shims are listed in sizes like 0,400mm or 1,200mm...Not sure how the Germans do it, but here in 'merica, I'd call that 4 hundred and 12 hundred millimeters. Do they actually mean .4mm and 1.2mm? I mean that would make sense right? if you put a 1200mm shim in there, the drive would be sticking out past your sidecar...Aaaaanyway, from the post I have hunted down, it would seem that 1.1mm of shim seems a little excessive, in Charley Vt's video, the drive he rebuilds used a .40mm shim. Guess I'll take a trip to Harbor freight and get a dial micrometer and a stand and try shimming it myself..I mean if it was overshimmed by .50, it still lasted 43K miles...how badly could I screw it up? Don't answer that!
