New Speedo Drives 3.9, 4.11. 4.375 & 4.6

Recommended Posts

Hi folks,

A question related to the posts above for the speedo drives: does anyone know the standard number of 'teeth' on the spiral gear on the output shaft of a 240Z/240K (FS5C71B) 5-speed, the one that drives the pinion gears being offered by GTv240z?

I suspect it's five but I really want to make sure.

Thanks,

Jeff

Originally 71b was ametal shaft drive, this is the plastic version from the bluebird 71b.

Appears to have 6

Thanks very much for the photo, looks like I have a challenge on my hands. I see there was an option for a 5-tooth gear, any thoughts anyone?

Today I removed the pinion drive and counted the teeth on the worm gear, based on each full turn being counted as one tooth, it has five. A 4.6 pinion drive when they become available will do very nicely.
