Multiquip 12789 Gearbox Assembly with Fan 1 1/4" Shaft - OEM Replacement Part

This gearbox assembly delivers power transmission and cooling for commercial riding trowels, featuring an integrated fan system and 1 1/4" shaft configuration. As a critical drivetrain component, this assembly transfers engine power to the trowel blades while the built-in fan provides essential cooling during extended finishing operations. When gearboxes fail, symptoms typically include unusual noise, vibration, loss of power transfer, or oil leakage around seals.

The complete assembly design simplifies replacement procedures, reducing downtime during repairs. The 1 1/4" shaft dimension ensures proper fitment and torque transfer in compatible Multiquip trowel models. This gearbox is engineered to withstand the demanding conditions of concrete finishing work, including continuous operation, heavy loads, and exposure to concrete dust and debris.
