Ferrari 512 BBI major service and transmission repair
It has been 10 years since this 1984 Ferrari 512BBI has been serviced so the owner shipped the car up so we could do a “major service” which includes replacing the timing belts, tensioner bearings and perform a valve lash. I drove the car 10 miles to get a feel for what else it may need and observed a nasty clunking noise in the transmission when in second gear so we have one more thing to repair on this car. Since we replace the bearings that support the timing belt drive pulleys we have to separate the engine from the transmission casting anyhow so it is no more work to get into the transmission to inspect for problems.
It turns out that the second gear cluster has some minor pitting as thought the gear (Ingranaggio 2 Velocitia) was not heat treated properly and the pitting is only on

few teeth. It is amazing that the noise was so prominent when driving the car with such a minor flaw on 3 of the 30 or so teeth. Anyhow, not sure how we are going to find new parts, I may research repairing this cluster because it is going to be a struggle to find these parts.
