The torque converter driver cutch assembly for the Coleman KT196 and CK196 196cc 6.5 Hp go-karts features a 3/4" central aperture for the drive shaft. Also known as the driver pulley, this clutch may also be found on other applications that run on 5.0 hp, 6.5 hp, 8.0 hp, and 9 hp engines.

This torque converter driver clutch is what is known as a Series 30 clutch assembly. A Series 30 clutch may be discerned from the very similar Series 20 by its asymmetrical pulley. The sliding sheave will be conical while the stationary sheave will be almost flat in comparison. On a Series 20 pulley, the two sheaves will both be angled.
