The Multiquip 20104 Shaft Urethane Seal Yellow is a genuine OEM replacement designed for Whiteman mortar and plaster mixer models including WM70, WM90, and WM63 series equipment. This factory-correct seal is engineered to fit the mixer shaft precisely, keeping material out of the bearing housing and protecting internal drivetrain components. Sourced directly from Multiquip, the 20104 matches the original urethane construction and yellow-coded specification of the seal installed at the factory. Compatible models include WM70SLF, WM70PLF, WM70S/P, WM90S/P, WM90PLF, WM90SLF, WM63SLF, WM63H8, WM63H5, and WM63E.
Key Features
- Urethane Material Grade: — Yellow-coded urethane construction delivers superior resistance to abrasion and chemical exposure common in mortar and plaster mixing applications.
- Direct Shaft Replacement: — Sized to drop into the original seal seat on Whiteman mixer shafts with no modification to the housing or shaft required.
- Broad WM-Series Fitment: — Confirmed fit across WM63, WM70, and WM90 mixer variants, covering a wide range of Whiteman plaster and mortar mixer configurations.
- Drivetrain Protection: — A properly functioning shaft seal prevents abrasive slurry and mixing material from migrating into the bearing cavity, which can cause accelerated bearing wear and shaft damage if left unchecked.
- Genuine OEM Specification: — Manufactured to Multiquip OEM standards, ensuring the seal profile, lip geometry, and material hardness match the original component exactly.
The shaft seal on a Whiteman mortar or plaster mixer sits at the point where the rotating mixing shaft exits the gearbox or bearing housing. Its job is to form a dynamic barrier that keeps mixing material — which is highly abrasive when it contains sand or aggregate — from working its way into the internal components of the drivetrain. When a shaft seal wears out or begins to leak, material ingress can quickly damage bearings and shaft surfaces, leading to costly repairs well beyond a simple seal replacement. Keeping this seal in good condition is one of the most cost-effective ways to protect the longevity of a mixer.
