Multiquip B1766 Automatic Clutch Weight

The Multiquip B1766 Automatic Clutch Weight is a genuine OEM component designed for Whiteman and International walk-behind power trowel series, including B46S90, JS36H55, JS36H90, BS46H90, BS46H11, CS24H55E, J36-M30, B46, and J3036H55 models. As an authentic Multiquip part, the B1766 is manufactured to the exact specification of the original component, ensuring a direct, drop-in fit with no guesswork. Keeping the centrifugal clutch system in proper working order is critical to smooth engagement and consistent trowel blade performance, and sourcing the correct OEM weight is the first step. DHS Equipment stocks this part and can help you confirm fitment for your specific trowel model before you order.

Key Features

• Genuine OEM Mass Tolerance — Manufactured to the precise weight specification required for correct centrifugal engagement — even minor mass variation in an aftermarket weight can cause sluggish or premature clutch engagement.
• Direct-Install Replacement — Matches the original mounting geometry and pivot hardware of the B46S90, J36-M30, and JS36H55 series clutch assemblies for a straightforward swap.
• Broad Walk-Behind Trowel Coverage — Confirmed fitment across multiple Whiteman and International walk-behind power trowel models including BS46H90, BS46H11, CS24H55E, J3036H55, and B46.
• Smooth Clutch Engagement — A correctly weighted flyweight allows the centrifugal clutch to engage at the proper RPM threshold, delivering consistent blade speed from startup and protecting the drivetrain from shock loading.
• Protects Downstream Clutch Components — A worn or incorrect weight forces the clutch to slip or engage erratically, accelerating wear on shoes, drums, and springs — replacing it promptly limits the scope of repair.

The automatic clutch weight is a flyweight component within the centrifugal clutch assembly of a walk-behind power trowel. As engine RPM rises, centrifugal force causes the weights to swing outward, engaging the clutch and transferring power to the trowel blades. The mass of each weight determines the precise RPM at which engagement occurs, so a worn, damaged, or incorrect weight directly affects when and how smoothly the blades begin to spin. If the weight is worn down or broken, the clutch may engage too late, slip under load, or fail to disengage fully at idle — all of which put stress on surrounding components and compromise finishing performance.
