Multiquip 9181 Worm Gear HD/HT Composite - OEM Replacement Part for Trowels

This composite worm gear is a critical drive component in Multiquip walk-behind and ride-on power trowels, transferring rotational power from the motor to the blade spider assembly. The worm gear mechanism provides the precise speed reduction needed to rotate trowel blades at optimal RPMs for floating and finishing concrete slabs.

Engineered specifically for heavy-duty (HD) and high-torque (HT) applications, this composite gear design offers excellent wear resistance and operates within the sealed gearbox environment. The worm gear drive system is fundamental to trowel operation—converting high-speed motor rotation into the controlled blade speeds required for professional concrete finishing. Regular gearbox oil checks prior to each use help ensure proper lubrication of this critical gear interface.

Compatible with the following Multiquip trowel models:

• BHN Series
• HDA Series
• HRT Series
• JWN24HTCSL

This worm gear is essential for maintaining proper blade rotation and torque transfer in your power trowel's gearbox assembly. Genuine Multiquip OEM part, sold by an authorized dealer.
