Hi all,

Working on the restoration of my pair of 260's and I want to hot rod one up to the high speed version with the speed plate that indicates speed range of 65-2650 RPM. I believe it is just the motor and countershaft pulleys that are different, everything else is the same. I only have one parts manual and it doesn't indicate anything for the high speed version. My top speed is 2000 on one of the machines, 1680 on the other but I now know that one speed plate is for 50Hz, the other 60Hz.

Anyway, if someone has the high speed 2650 version, I would appreciate knowing what the 2 pulley diameters are.

Thanks!

Cheers
