Included in the kit

The kit includes a custom bracket that supports the motor and the standoffs that attach to the mounting bracket. Also included are the standoffs, motor mounting bracket, 15-tooth motor pulley, 30-tooth spindle pulley, toothed drive belt and mounting hardware. Not included are the headstock and stepper motor (P/N 67127), which must be purchased separately. (A 10-tooth drive pulley is also available for special order for a slower 3:1 drive ratio instead of the standard 2:1 ratio. It is part number 65003.)

Installing the stepper motor

The conventional installation and an alternate space-saving alternative are shown below. If using the alternative method, flats must be ground on the spindle shaft to accommodate the pulley set screws. If this is not done, the galling of the spindle shaft caused by the set screw points can make the pulley difficult or impossible to remove from the shaft.

The first photo (Figure1) below shows the conventional configuration with the timing belt pulley replacing the standard 2-position V-belt pulley. This gives the most support for the drive belt. Although not originally designed for it, the motor can also be installed in the other direction as shown in the right-hand photo (Figure 2) if space requires. (The standard two-position pulley has been retained here in order to cover the bearings and preload nut.) Additional flats should be ground on the spindle shaft to accommodate the timing belt pulley set screws. The headstock and stepper motor shown here are NOT included with the kit.
