To replace a PD60 conveyor gearmotor, you’ll only need a 10 mm wrench.

Loosen the four bolts around the face of the gearmotor, then gently slide the gearmotor off the shaft.

To replace the gearmotor, line up the shaft and keys and gently slide the new gearmotor into place. Then, simply snug down the bolts and tighten with the 10 mm wrench, ensuring the gearmotor is snugly in place.
