Review on Racing Power R9446 Alternator Pulley by Dave Mosby

I use this as a pulley and fan on a treadmill motor. I am using a treadmill motor to upgrade my harbor freight wood lathe to a variable speed lathe. The pulley fits perfectly on the motor shaft and the fan provides proper cooling. I do not use a treadmill flywheel that also acts as an engine cooling fan. If you're thinking of upgrading your wood lathe to a treadmill motor, this pulley is perfect.
