on 12 October 2009 my 1995 Ural Tourist (20,948 km's) developed an odd growling noise and vibration followed by a massive rear main seal leak. I rode it 60 miles (yes, MILES) home w/ no problems besides numb feet from the vibration. Hey, the closer to home I got before it blew up the easier it would be to get someone to grab my truck and come rescue me. I suspected a broken crankshaft and these engines are relatively inexpensive anyway! But, as usual, the old whore surprised me and made it home, shaking and hammering the whole way back! So the tear-down begins... All in all, NOT TOO BAD!!! Upon disassembly, the problem turned out to be nothing more than a failed rear crankshaft bearing! This engine has had a horrible left rod knock since I bought it @ 10K so I decided to replace the whole crankshaft assembly as these are only $300! Look through this gallery for the details and modifications I have made. A special thanks has to go to my "employee" Rob Nelson for doing the complete re-assembly of the engine while I was busy w/ other business work and the funeral of my mother-in-law. Thanks Rob (aka "Don") :)
