The Multiquip 512518 Drive Pulley is a genuine OEM component designed for WM45H and WM45HE Whiteman plaster and mortar mixers. Sourced directly from Multiquip, this pulley is manufactured to the same specifications as the original part, ensuring a correct fit and consistent power transfer from the engine to the drum drive system. If you're servicing a WM45H or WM45HE mixer, part number 512518 is the verified replacement to keep your machine running as intended.
Key Features
- Genuine OEM Construction — Machined to the original dimensional specifications, so pulley diameter, bore size, and belt groove profile match the factory drive system exactly.
- Direct Belt-Drive Replacement — Mounts in place of the worn or damaged pulley without alteration, maintaining correct belt alignment and tension across the drive train.
- Confirmed Fitment — Verified for WM45H and WM45HE Whiteman mortar and plaster mixer models.
- Consistent Drum Speed — A properly sized drive pulley maintains the correct drum rotation speed, delivering thorough, even mixing of mortar and plaster batches every cycle.
- Protects Belt and Bearings — A worn or damaged pulley causes belt slippage, uneven wear, and premature bearing failure; replacing it promptly preserves the rest of the drive system.
The drive pulley is a core component of the belt-drive system on Whiteman mortar and plaster mixers. It transfers rotational power from the engine to the drum, using a V-belt to maintain the correct mixing speed under load. When the pulley becomes worn, cracked, or damaged, belt slippage occurs, leading to inconsistent drum rotation, accelerated belt wear, and potential overloading of the engine. Replacing the pulley with the correct OEM part restores full drive efficiency and prevents cascading wear on surrounding drive components.
