The Multiquip 20104-002 is a genuine OEM Shaft Urethane Seal (Yellow) designed for Whiteman plaster and mortar mixer models including the WM63, WM70, and WM90 series. As an authorized OEM replacement, this seal meets the original design specifications and installs directly into your Whiteman mixer without any modification. It is compatible across a wide range of WM-series configurations including electric, Honda-powered, and MPower-engine variants. Keeping the correct shaft seal in service is essential to maintaining proper drum rotation and preventing material contamination or fluid ingress around the mixer shaft.
Key Features
- Urethane Construction for Harsh Mix Environments — The urethane material resists abrasion and chemical exposure from cementitious and plaster mixes, outlasting standard rubber seals in high-wear shaft applications.
- Genuine OEM Component — Sourced directly from Multiquip as part number 20104-002, this seal matches the original specification used on WM-series Whiteman mixers at the factory.
- Broad WM-Series Fitment — Confirmed compatible with WM63E, WM63H5, WM63H8, WM63SLF, WM70PLF, WM70S/P, WM70SLF, WM90PLF, WM90S/P, and WM90SLF mixer models.
- Drop-In Shaft Replacement — Designed to seat correctly on the mixer shaft, this seal restores the original sealing surface contact and compression without machining or adaptation.
- Prevents Contamination and Leakage — A worn or failed shaft seal allows mix material to migrate into the drive assembly, accelerating wear on internal components and leading to costly repairs.
The shaft seal on a Whiteman mortar or plaster mixer creates a barrier between the rotating drive shaft and the drum opening, preventing wet mix material, slurry, and moisture from entering the gearbox or bearing housing. When this seal degrades or tears, abrasive material works its way into the drivetrain, causing accelerated wear on bearings and internal gear surfaces. Replacing the Multiquip 20104-002 Shaft Urethane Seal Yellow at the first sign of leakage or material buildup around the shaft is the most cost-effective way to protect the mixer's drivetrain and extend overall service life.
