Import 921718-000 Motor Pulley Assembly Mill Drill

Product Description

The IMPORT 921718-000 is a motor pulley assembly designed as a replacement drive component for mill drill combo machines. This assembly provides the mechanical interface between the motor shaft and the drive belt, transferring rotational power through the machine's spindle system. It is installed by machinists, mill-drill service technicians, and experienced mechanical tradespeople performing drivetrain maintenance or repair. The kit includes all components needed for a complete assembly: a key, motor lower pulley half, pin, screw, and sleeve. The assembly weighs 15 pounds.

This motor pulley assembly is intended for use with mill drill combo machines where the original motor pulley has worn, cracked, or requires replacement as part of a drivetrain overhaul. It is suited to shop environments running benchtop or floor-standing mill drill units that share a common motor-to-spindle belt drive configuration. Technicians performing scheduled maintenance or responding to belt slippage and vibration complaints will find this kit provides all the hardware needed to restore proper drive function.

Installation Notes

Installation should be performed by a qualified machinist or mechanical technician familiar with mill drill drivetrain systems. Disconnect and lock out all electrical power to the machine before beginning disassembly. Remove belt tension before extracting the existing pulley assembly, and ensure the key and set screw are fully seated and secured before reassembling the belt guard and restoring power.
