The Multiquip 502213 Small Pulley is a genuine OEM component designed for Essick and Whiteman plaster and mortar mixer models, including EM70P/S, WM63E, WM63H5, WM63H8, and WM70S/P. As a direct OEM replacement sourced through Multiquip's authorized parts network, part 502213 is manufactured to the same specifications as the original pulley installed at the factory. This pulley seats and aligns exactly as the original, ensuring correct belt tension and drive engagement without adaptation. If you're servicing any of the compatible Essick or Whiteman mixer models listed above, verifying your part number against 502213 is the surest way to confirm a correct fit.
Key Features
- Genuine OEM Drive Geometry — Machined to the original pulley profile, ensuring correct belt tracking and load transfer across the mixer drive system.
- Direct Drop-In Replacement — Mounts to the same shaft position as the original, with matching bore and groove dimensions for straightforward installation.
- Broad Mixer Compatibility — Fits EM70P/S, WM63E, WM63H5, WM63H8, and WM70S/P Essick and Whiteman plaster and mortar mixers.
- Consistent Belt Engagement — A correctly sized small pulley maintains proper drive ratio, keeping drum rotation speed and torque output within spec throughout the mix cycle.
- OEM Parts Sourcing — Supplied as a genuine Multiquip part, backed by the manufacturer's parts program for full traceability and quality assurance.
The small pulley is a core component of the mixer's belt-drive system, working in tandem with the larger driven pulley to transfer power from the engine or motor to the drum. Its diameter determines the drive ratio, which directly controls how much torque and rotational speed reaches the drum. When the small pulley becomes worn, cracked, or out of round, belt slippage increases, drive efficiency drops, and the mixer may struggle to turn under load or fail to maintain consistent drum speed. Replacing a worn pulley with a correctly sized OEM unit restores the drive system to its intended operating balance.
