Multiquip 20540 Heavy Duty Gearbox Case with 2" Handle - OEM Replacement Part

This heavy-duty gearbox case assembly with integrated 2-inch handle mount is a critical structural component for HDA Series walk-behind trowels. The gearbox case houses the power transmission system that transfers engine output to the rotor assembly, governing rotational speeds from 35 to 225 rpm across the 46-inch working path. This case is designed to support the handle tube mounting hardware and maintain precise alignment of the input and output shafts under the demanding conditions of concrete finishing operations.

The case accepts standard or optional Quick Pitch™ handle configurations, mounting via 3/8-16 hardware to the upper gearbox position. Built to withstand the 327 lb operating weight and vibration loads inherent in professional troweling applications, this heavy-duty casting ensures reliable power transfer throughout the machine's service life. Signs that replacement may be needed include visible cracks in the casting, oil leakage around seals, unusual vibration during operation, or damage to handle mounting points.
