[QUOTE="davidd, post: 56530, member: 1177"] Yes, the indicators you mention are tough to explain. However, I think this has been a troublesome area for others. Phil Irving recommended the Oilite bushing in the street bikes. For racing he was concerned that the sintered bushings would not survive the loading. I remember that Bill Hoddinot and Sid rebuilt the Black Lightning Cooper car driven by David Cooper. It all worked well, except they replaced the bushings in question with solid bronze items and they failed the first time out despite their efforts to channel extra oil to the area. Additionally, Dave Mattson said these bushings only lasted one trip to Bonneville. He replaces them after every visit. I am not an expert on twin gearboxes, but if I look at Trevor's post above, I think I can see why the Oilite bushing was recommended by Irving. It may be that the shaft developed a wobble that did not damage already worn bushings, but could not stand the constraints of the new bushings. David [/QUOTE]
