I have a 2000 Ural Deco Classic with electric start and reverse gear. About 5000 miles ago, I dropped a tool and sheared off the reverse-throw set-screw at the back of the tranny flush to the case. Since then, the screw has migrated in the “right” direction, that is, the one that impedes getting into reverse, but does not lock out the forward gears. As a result, I can engage enough of the reverse gear to use it for a dodgy parking brake, but not for actual rearward motion. With the transmission still in the bike, I made several futile attempts to remove the stub of the screw. But I found the location inaccessible and gave up. Recently I bit the bullet and took the transmission out. Picture # 1 is the rear view of same. Picture #2 is a close-up of where reverse-throw set-screw SHOULD be. And here is where my big mystery begins: I could swear that the set screw resided in the left-hand and shorter of the two near-circular projecting posts that together form a figure-eight. And that would be consistent with the tool marks on that post that I made in my attempts to remove the stub of the screw while the transmission was still in the bike. But, as in the Picture #3—as well as in every photo and diagram of Ural & Dnepr transmissions I have looked at going back to dirt—the set screw sits in the right-hand post. Further, the right-hand post on my transmission is as smooth as a baby’s bottom, with no stub of a screw visible, as if there had never been one at all! So, amateur that I am, I just cannot figure it out. Do I have a rare model exception in which the screw is indeed on the left? Or no screw at all? Can the sheared-off stub—assuming it is in the right-hand position where it should be—have been so-well camouflaged by oxidation and grime across seven-odd years so as to give no surface appearance? Am I safe to just telling the machinist to drill-and-extract at the center of the right-hand post? Or do I need to do an “exploratory disassembly” to determine the true state of affairs? Or is there something else that you-all will no doubt think of? Thanks and blessings for any and all responses!
