The Multiquip 530181 is a genuine OEM Center Engine End Paddle Arm designed for Whiteman mortar mixer models WM45H, WM45HCE, and WM45HE. Sourced directly from Multiquip, this part matches the original component specification for a straight-forward, no-guesswork replacement. Keeping your mixer's paddle assembly in proper working order ensures consistent, thorough mixing and protects surrounding drivetrain components from the strain caused by a worn or damaged arm. If you are restoring full mixing capacity to your WM45H-series machine, 530181 is the correct part to order.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional standards, ensuring the arm withstands the continuous torque and abrasion loads inside a mortar mixer drum.
- Direct Drop-In Replacement — Engineered to mount at the center engine end of the paddle shaft, aligning with existing hardware and mounting points on the WM45H-series mixer.
- Confirmed Fitment — Verified for WM45H, WM45HCE, and WM45HE Whiteman mortar mixers; use part number 530181 to confirm compatibility when ordering.
- Restored Mixing Performance — A fully intact paddle arm drives material from the engine end of the drum through the mix, ensuring uniform consistency batch after batch.
- Protects Adjacent Components — A cracked or deformed paddle arm places uneven stress on the paddle shaft and gearbox; replacing it promptly limits secondary wear on those components.
The paddle arm is a structural mixing component that attaches to the rotating paddle shaft inside the drum. Its job is to push and fold material — mortar, plaster, or similar mixes — as the shaft turns, ensuring the batch blends evenly from end to end. The center engine end arm sits at the engine-side midpoint of the shaft, making it one of the highest-stress positions in the assembly. When a paddle arm cracks, bends, or breaks, mixing becomes uneven, output quality drops, and the remaining arms and shaft bearings absorb additional load that accelerates their wear.
