Re: Asking for a favor
The chatter on my newly, professionally restored engine seemed innocuous to begin with but got progressively worse. I chased all kinds of theories and opinions, mainly dealing with my float a motor mounts. Around 5,000 miles I pulled the engine and discovered that the builder or machinist had "balanced" my clutch by adding weld to the pressure plate in several locations. Opposite each weld on the mating surface was a very clear "hot spot" where the disc had been chattering. Pressure plates must be drilled, not welded as welding distorts the metal and causes the surface to have high and low spots. New pressure plate and all has been well!
