Multiquip 24248 Clutch 35° 4" Pos-Grip 1 1/8" Bore - OEM Replacement Part

This centrifugal clutch assembly ensures reliable power transfer from the engine to the spider assembly on walk-behind power trowels during concrete finishing operations. The 35-degree engagement angle and 4-inch Pos-Grip design provide smooth, consistent engagement while the 1 1/8-inch bore ensures proper shaft fitment for compatible models.

Critical for maintaining proper trowel operation, this clutch component works directly with the spider assembly and trowel arms to deliver smooth blade rotation during both floating and finishing stages. When troubleshooting issues like trowel bouncing, uneven swirls, or inconsistent blade pitch, technicians should verify clutch engagement as part of the complete drive system inspection. The Pos-Grip design helps maintain consistent torque transfer even under varying load conditions common during concrete finishing work.

Regular inspection of the clutch assembly should be performed alongside trowel arm straightness checks and blade pitch adjustments. Proper maintenance of this component ensures the spider assembly rotates smoothly without excessive vibration that could affect the quality of the concrete finish or damage trowel arm bushings and bronze components.
