Multiquip 12906 Shaft Gear Box Input with Fan - OEM Replacement Part

This gearbox input shaft with integrated fan is a critical drivetrain component for Multiquip power trowels, transferring engine power into the gearbox while providing essential cooling airflow to prevent overheating during operation. The shaft's precision-machined splines and bearing surfaces ensure proper engagement and smooth power transmission under the demanding loads of concrete finishing work.

As a wear-prone component subject to high rotational speeds and torque loads, this input shaft requires inspection during routine maintenance intervals. Signs that replacement may be needed include excessive vibration, unusual noise from the gearbox area, difficulty engaging drive, or visible wear on the splines or fan blades. The integrated fan design is essential for maintaining proper operating temperatures in the gearbox assembly during extended troweling operations.
