Re: Speedo Drives

Hi Fred, I think the only difference is the speedometer pinion drive gear that is fitted in the350/400/Islero transmission is just not installed in the rest of the noted models. I bought a spare transmission (an Espada unit) from Jon Pollock a few years ago and was planning to install it in the 400 (since it had fresh synchros, bearings, etc.), but when I had it on the bench, I noticed that the hole that normally held the speedo drive was fitted with an aluminum plug. I removed the plug and inspected the interior and noticed that there was no gear fitted on the main shaft to drive the speedo. So my opinion/conclusion is that I could probably remove the speedo drive parts from my current 400 transmission and install them in this Espada box. I"m not 100% sure of this but it looks possible. That requires a lot more ambition than I can currently muster, so I will live with the tired 1st and 2nd synchros for a while longer.
