The Multiquip 20104 Shaft Urethane Seal Yellow is a genuine OEM component designed for Whiteman mortar and plaster mixer models including the WM70, WM90, and WM63 series. This shaft seal is manufactured to Multiquip's original specifications, ensuring the correct material grade, compression characteristics, and dimensional fit for a direct installation. Compatible models include the WM70SLF, WM70PLF, WM70S/P, WM90S/P, WM90PLF, WM90SLF, WM63SLF, WM63H8, WM63H5, and WM63E. Sourced directly from Multiquip, part 20104 is the correct OEM replacement when your original seal shows signs of wear, cracking, or leakage.
Key Features
- Urethane Construction for Seal Integrity — Yellow urethane material provides strong resistance to abrasion, mortar slurry, and moisture that a rubber or low-grade seal cannot match in mixer applications.
- Genuine OEM Part — Manufactured by Multiquip to the same specification as the original, so the seal seats correctly against the shaft without gaps or misalignment.
- Broad Whiteman Mixer Compatibility — Fits WM70, WM90, and WM63 series Whiteman mortar and plaster mixers across multiple configurations including SLF, PLF, H8, H5, and E variants.
- Prevents Material Contamination and Shaft Damage — A functioning shaft seal keeps mortar and water away from the drive components; a worn seal allows slurry intrusion that accelerates shaft and bearing wear.
- Direct Installation — Engineered to match the original shaft diameter and housing dimensions on covered Whiteman mixer models, replacing the existing seal without machining or modification.
The shaft seal on a mortar or plaster mixer forms a barrier between the wet mixing drum and the mechanical drive components underneath. It wraps around the rotating output shaft to prevent mortar slurry, water, and fine aggregate from migrating into the gearbox or bearing housing. When the seal degrades — common signs include visible leakage around the shaft base, dried mortar buildup near the seal area, or increased shaft play — it allows abrasive material to reach components that are difficult and expensive to replace. Keeping the Multiquip 20104 Shaft Urethane Seal Yellow in good condition is one of the most cost-effective ways to extend the service life of your Whiteman mixer drivetrain.
