| Post subject: | 750 Paso Bad news (Death???) |
Hello All, I bought this bike 2months ago and with your help, had just finished changing all the fluids, mounting new tires, brake pads, chain alignment, belts, valves, plugs, cleaning the webber, fuel lines ect. I think the tranny on the Ducati blew up. I hauled the damn bike 1,600 miles north for a chance to ride it through oregon and spend some time in Eugene and Portland. It was to be our vacation with in a vacation aboard a classic piece of Italian Iron. We made it 45 miles from the beach house before tragedy struck. A big bang/clunk followed by a chorous of grinding sounds like a marble in a blender. I had just passed a fully loaded logging truck and signaled back in when it hit. I pulled in the clutch and coasted onto the median. The motor still idled nicely but things didn't sound good down below. It's now back on the trailer due to be hauled back to Mammoth. It's a beautiful machine but I'm scared to hear what Tony will quote me on the reserection. When I rolled to a stop. I could see that the chain was sagging full of slack so I pulled the chain and sprockets the front countershaft sprocket was no longer centered, the seal bent, and no sign of a bearing on the inside supporting it. I imagine the countershaft bering disintegrated. Has this what happened to anyone else's paso? Can just the transmission be replaced or does this involve splitting the cases. I would imagine a motor swap would be the easiest and least expensive solution. Your thoughts and suggestions? I'm the 3rd owner, The guy I got it from races motorcross professionally and maintains all of his own machines. He's anal, he wins, and I checked the chain tension and alignment when doing my usual maintenance. The bike had 19, 925miles on it. He said he had replaced the chain and both sprockets and that he though it was strange that the front sprocket was missing two teeth. I rode it about 500 miles before doing any of the major maintenance listed above. Not that it matters at this point but I'm wondering if the orignal owner could have run the chain too tight and stressed the bearing? Thanks, Gunther |

Same exact thing happen to me with an engine I bought off ebay. I rode 10 miles after I installed it and thats all I got out of it. Same countershaft problem you described. I just ended up doing an engine swap as a fix. I still have the broken engine in the garage. So I am curious what replies we hear in this thread... |
