The Multiquip 3428 Fan Blade WM120 is a genuine OEM component designed for the WM120 Whiteman plaster and mortar mixer. Sourced directly from Multiquip, this fan blade is manufactured to the exact pitch, diameter, and mounting specification required for proper airflow and engine cooling on WM120 equipment. If your current blade is cracked, chipped, or out of balance, swapping in the correct OEM part restores cooling efficiency and protects the engine from heat-related wear. Confirm your model against the WM120 before ordering to ensure a direct fit.
Key Features
- Correct Blade Geometry — Manufactured to the exact pitch and diameter spec for the WM120, ensuring the fan moves the right volume of air across the engine at all operating speeds.
- Genuine OEM Construction — Produced by Multiquip to the same material grade and balance tolerance as the original, so the blade runs true without vibration at speed.
- Direct-Fit for WM120 Mixers — Mounts to the existing hub and fastener pattern on Whiteman WM120 mortar and plaster mixers with no rework needed.
- Protects Engine from Overheating — A worn or damaged fan blade reduces airflow, causing operating temperatures to climb and accelerating wear on engine components — this OEM blade restores the designed cooling margin.
- Balanced for Smooth Operation — Proper blade balance eliminates vibration at the fan hub, reducing stress on the crankshaft and surrounding components over the life of the machine.
The fan blade on a mortar mixer engine draws cooling air across the cylinder fins and engine block to maintain safe operating temperatures under continuous load. When the blade is intact and correctly balanced, the engine runs within its designed heat range. A cracked, chipped, or bent blade disrupts airflow and introduces vibration, which over time can lead to overheating, premature engine wear, and damage to adjacent components. Replacing a damaged blade promptly with the correct OEM part is one of the most cost-effective ways to protect the engine on a working mixer.
