Multiquip 12908 Worm Gear RH 2.00PD - OEM Replacement Part for Walk-Behind Trowels

This right-hand worm gear is a critical power transmission component in the gearbox assembly of Multiquip walk-behind trowels. Located beneath the engine, the gearbox transfers power to the rotor and governs the rotational speed of the trowel blades (35-225 rpm). This precision-machined worm gear features a 2.00 pitch diameter with 1.002 inch diameter and 4.000 inch length, engineered to handle the demanding loads of concrete finishing operations.

The gearbox contains both input and output shafts that work in conjunction with this worm gear to drive the spider assembly and trowel blades. Regular inspection of gearbox components is essential, as worn or damaged gears can affect blade rotation smoothness and finishing quality. Symptoms of a failing worm gear include unusual noise, vibration, inconsistent rotor speed, or difficulty maintaining proper blade rotation during floating and finishing operations.

Compatible with the following Multiquip walk-behind trowel models:

• HDA-SERIES
• HTN27KTCSL
• JWN24HTCSL
