The Multiquip 20743 ISO Snub Krofund Dynamic Washer is a genuine OEM component designed for STX55, HTX44, PRX, and WRS series ride-on trowels and roller screeds. As a direct OEM replacement, 20743 is sourced to match the original manufacturer's specifications, ensuring consistent fit and function across the wide range of compatible Whiteman and Multiquip machines it serves. Confirmed fitment includes STX55J6, STX55Y6, STXDF, STXD6i, HTX44Y5, HTX44Y4, HTX44K5, HTX44K4, HTXG6DF, HTXD6i, HHXG5, HHXD5, HHXD5-ES, HHXDF4-DF5, PRX, WRSPUDF, WRS5200, and WRS5200DFPU.
Key Features
- Genuine OEM Construction — Manufactured to the same specification as the original, ensuring the washer seats and loads correctly within the dynamic assembly without dimensional variation.
- Direct Drop-In Replacement — Engineered to match the original mounting interface of the ISO snub isolator system, allowing straightforward installation without reworking surrounding components.
- Broad Whiteman and Multiquip Compatibility — Fits STX55, STXDF, STXD6i, HTX44, HTXG6DF, HTXD6i, HHXDF4-DF5, HHXD5, HHXG5, PRX, WRS5200, WRSPUDF, and WRS5200DFPU machines.
- Vibration Isolation Integrity — Correctly rated for dynamic loading conditions; a worn or missing washer in the snub isolator system can allow excessive vibration transfer and accelerate wear on adjacent components.
- Multi-Platform Serviceability — A single part number covers hydrostatic ride-on trowels, hybrid power floats, and ride-on roller screeds, simplifying parts inventory for mixed fleets.
The ISO Snub Krofund Dynamic Washer is a load-bearing isolation component used within the snubber or vibration damping assembly of ride-on trowels and roller screeds. Its role is to manage dynamic forces — absorbing and distributing shock and vibrational loads that occur during machine operation — so those forces do not transmit directly through the frame or damage surrounding hardware. When this washer wears, compresses beyond its design limit, or is missing entirely, the isolator assembly loses its ability to buffer dynamic loads effectively, leading to increased vibration felt by the operator and potential accelerated wear on the mounting hardware and connected components.
