Multiquip 45039 Final Drive Gearbox - OEM Replacement Part for Trowels

The final drive gearbox is a critical power transmission component that transfers hydraulic or engine power to the trowel rotors, enabling the finishing blades to rotate and complete concrete surface work. This assembly houses the gear reduction system that converts high-speed input into the controlled rotational speeds needed for panning and burnishing operations.

In Multiquip ride-on trowel systems, the gearbox connects directly to the spider assembly and blade configuration, making it essential for achieving proper RPM control and torque delivery to the work surface. Drive system efficiency depends on the integrity of this gearbox, as it ensures optimal power transfer from the engine to the finishing rotors. Regular inspection during maintenance intervals should include checking for unusual noise, vibration, or oil leakage from the gearbox housing, as these are common failure symptoms requiring replacement.

This final drive gearbox is compatible with the following Multiquip trowel models:

• PRX Series Trowels
