Multiquip 22206 Chassis Cast Vibration Isolator

The Multiquip 22206 Chassis Cast Vibration Isolator is a genuine OEM replacement component designed for Whiteman and International walk-behind power trowel models including BS90C, BH11C, BH90C, B46, JS60C, JH90C, JH55C, HDA-Series, J36-M30, CS24H55E, BS46H11, BS46H90, JS36H90, JS36H55, B46S90, and J3036H55. As a direct OEM part sourced through Multiquip's authorized supply chain, the 22206 is manufactured to the same specifications as the original component it replaces. This chassis casting forms the structural backbone of the vibration isolation system, making correct fitment and material integrity critical to proper machine operation. DHS Equipment stocks this part to keep your Whiteman trowel turning without unnecessary delays.

Key Features

• Genuine OEM Cast Construction — Produced to Multiquip's original casting specifications, ensuring the same wall thickness, bore geometry, and material grade as the part it replaces.
• Structural Drop-In Replacement — Matches the original mounting points and bolt pattern for the vibration isolation assembly, allowing direct installation without rework or machining.
• Broad Trowel Series Compatibility — Confirmed fitment across BS, BH, B46, JS, JH, HDA, CS, and J36-M30 series Whiteman and International walk-behind power trowels.
• Isolates Engine and Blade Vibration — The cast chassis housing anchors the isolation mounts that absorb drivetrain and blade vibration, protecting operator hands and reducing stress on the frame over long finishing runs.
• Maintains Handle and Blade Control Accuracy — A cracked or worn vibration isolator chassis allows unwanted flex in the isolation system, degrading blade pitch response and handle feel during concrete finishing.

The chassis cast vibration isolator serves as the rigid structural housing that holds the vibration-dampening mounts between the trowel's engine or gearbox assembly and its main frame. By containing and anchoring these isolation mounts, it prevents engine and blade-generated vibration from transmitting directly into the operator handles and the machine frame. When this casting cracks, distorts, or wears at the mount bores, the isolation system loses its clamping integrity — leading to increased handle vibration, accelerated wear on surrounding components, and reduced precision in blade pitch adjustment during finishing operations.
