Multiquip 2003 Gear Worm & C/Shaft LH - OEM Replacement Trowel Part

This left-hand worm gear and countershaft assembly drives the spider rotation on walk-behind power trowels, converting motor power into the blade rotation required for concrete finishing operations. The worm gear design provides precise speed reduction and torque multiplication within the trowel's gearbox, enabling smooth blade operation across the full RPM range during floating and finishing work.

As a critical drivetrain component, this gear assembly experiences constant load during troweling operations and should be inspected during routine gearbox maintenance. Signs of wear include unusual noise during operation, reduced blade speed, or difficulty achieving proper rotation. When servicing, ensure the gearbox is filled with the proper oil specification (Chevron Cetus Hipersyn 460 or MQ Part #20111) to maintain lubrication of the worm gear interface.

This left-hand configuration is specifically designed for trowel arms with the appropriate blade rotation direction. Always verify the rotation direction of your trowel arm before ordering replacement gearbox components.

Compatible with the following Multiquip models:

• JRT Series Walk-Behind Trowels
