Wheel horse B-100 tranny pulley

[chevyaddict83 39]

Was hoping to find out the pulley size for the transmission. Need the inner diameter that actually rides on the shaft. I know I need a 4" outer. The tranny is going in an 856. Need a crawler.

4-speed transmissions are 3/4" input shaft and 6-8 speeds are 5/8" input shaft...

How about the keyway size. All help is appreciated

The 4" with 3/4" bore pulley on the 856 uses 3/16"x3/4" (.740" long) #9 Woodruff key

The 6-1/2" with 5/8" bore pulley on a 1977 8-speed uses 5/32"x5/8" (.612" long) #6 Woodruff key
