Re: Speedo Drives

Interesting Jack.That"s good to know, and it"s also worth noting that it is that very speedo pinion drive that caused all my transmission problems with Lamborghini N.A. back in 1983.Long story, but they had apparently installed it with an incorrect method (hammered it in?) causing it to "ping" loudly with every revolution. I guess they nicked the gear facing.That"s when Bill Stewart sold me an old (smooth) pinion and Claudio replaced it. Another situation where we need the experienced folks to document the correct rebuild methods. Best, Fred
