The Multiquip 20104-002 Shaft Urethane Seal Yellow is a genuine OEM shaft seal designed for Whiteman plaster and mortar mixers across the WM63, WM70, and WM90 series. As an OEM-sourced component, it matches the original material grade and dimensional tolerancing specified for these mixers, ensuring a correct and consistent installation every time. Compatible models include the WM63E, WM63H5, WM63H8, WM63SLF, WM70PLF, WM70S/P, WM70SLF, WM90PLF, WM90S/P, and WM90SLF — making 20104-002 a single part number that covers a wide range of Whiteman mixer configurations. Sourcing directly through DHS Equipment ensures you receive the correct OEM part backed by verified fitment.
Key Features
- Urethane Material Grade — Yellow urethane construction delivers superior resistance to abrasion and the alkaline slurry conditions common in mortar and plaster mixing applications.
- OEM-Matched Shaft Dimensions — Manufactured to the exact shaft diameter and sealing lip profile of the original, ensuring a drop-in installation on the mixer output shaft without rework.
- Broad Whiteman Mixer Compatibility — A single part number covering WM63, WM70, and WM90 series models, including electric, Honda H5/H8, LF, and S/P variants.
- Prevents Costly Mix Contamination — A correctly seated shaft seal keeps mortar and slurry out of the bearing cavity; a worn seal allows abrasive material to migrate inward, accelerating bearing wear and leading to shaft damage.
- Genuine OEM Replacement — Sourced directly from Multiquip, this part carries the same part number — 20104-002 — used by authorized Whiteman service centers, ensuring the right part the first time.
The shaft seal on a Whiteman mortar mixer serves as the primary barrier between the rotating output shaft and the mixer drum environment. It prevents abrasive mix material — including cement, lime, and aggregate slurry — from migrating along the shaft and into the drivetrain and bearing housing. When this seal degrades or tears, mix contamination accelerates internal wear on bearings and other drivetrain components, leading to significantly higher repair costs. Replacing a worn shaft seal promptly with the correct urethane part keeps the drivetrain protected and maintains consistent mixer output.
