The Multiquip 0250 Automatic Clutch Assembly 1" Bore is a genuine OEM component designed for B Series, BS46, JS36, J36-M30, and B46 series walk-behind and ride-on power trowels. This clutch assembly is sourced directly from Multiquip and built to the same specifications as the original part installed at the factory. Confirmed fitment includes the BS46H11, BS46H90, JS36H55, JS36H90, J36-M30, B46, and B46S90 models, covering both domestic Whiteman and international walk-behind trowel configurations.
Key Features
- Genuine OEM Clutch Engagement Accuracy — Manufactured to exact centrifugal engagement specs, ensuring the clutch locks up at the correct RPM threshold for your trowel's engine output.
- 1" Bore Fit — Machined to a 1" bore diameter for direct shaft installation on compatible Multiquip trowel drivetrains with no sleeve or adapter needed.
- Broad Trowel Series Coverage — Fits BS46, JS36, J36-M30, B46, and B46S90 models across both Whiteman walk-behind and international walk-behind power trowel lines.
- Consistent Blade Engagement — A properly functioning automatic clutch allows the trowel blades to engage smoothly at operating speed; a worn clutch causes blade slip, erratic engagement, and uneven concrete finishing.
- Drive System Protection — The centrifugal clutch absorbs startup shock loads, protecting the gearbox and blade spider from damage during cold starts and engagement under load.
The automatic clutch assembly is the mechanical link between the engine and the trowel's blade drive system. As engine speed rises, centrifugal force causes the clutch shoes to expand outward and engage the clutch drum, transferring power to the blades — allowing the operator to start the engine without the blades spinning immediately. When the clutch wears, the shoes lose their grip, causing slipping, delayed engagement, or failure to drive the blades at working speed, which directly affects surface finish quality and operator control. Replacing a worn clutch assembly restores crisp, predictable blade engagement and protects downstream drivetrain components from the stress of a slipping or dragging clutch.
