Racing Power R9446 Alternator Pulley and Fan

I am using this as a pulley and fan on a treadmill motor. I am using the treadmill motor to upgrade my harbor freight wood lathe to a continuously speed adjustable lathe. The pulley fits the motor shaft perfectly and the fan provides proper cooling. I am not using the treadmill fly wheel which also acted as the motor cooling fan. If you are thinking about converting a wood lathe to use a treadmill motor this the perfect pulley.
