Key Features

• Genuine OEM Retention Spec — Manufactured to the exact groove dimensions and spring tension required for correct axial retention in Multiquip trowel assemblies, preventing shaft or component walk during operation.
• Drop-In Replacement — Matches the original Truarc 5100-37 profile for tool-standard snap-ring installation with no fitting or modification to the housing required.
• Broad Trowel Family Coverage — Fits J36, JA, B46, BA, CA, JS, BS, and LD6 series trowels, including both walk-behind and ride-on configurations from the Multiquip and Whiteman product lines.
• Prevents Costly Component Drift — A worn or missing retaining ring allows rotating components to shift axially, accelerating bearing and gear wear and causing premature assembly failure.
• OEM Part Number Verified — Sourced directly through Multiquip's authorized parts chain; this part is the confirmed part number for this Truarc ring application across all listed trowel models.

A Truarc snap ring is a precision-formed retaining ring that seats into a machined groove on a shaft or inside a bore to lock a component in its correct axial position. In power trowel assemblies, these rings secure rotating elements such as bearings, gears, and drive components against lateral movement during the high-cycle vibration and rotational loads troweling generates. When a snap ring fails, becomes fatigued, or is lost during service, the components it retained can migrate out of position, leading to accelerated wear on adjacent parts, increased play in the drive train, and potential assembly failure mid-pour — exactly the wrong time for a finishing machine to go down.
