Key Features
- Genuine OEM Drive Geometry — Manufactured to the original pulley diameter and belt groove profile, maintaining correct belt speed and torque transfer for consistent drum rotation.
- Drop-In Installation — Matches the original shaft bore and keyway dimensions on compatible Whiteman and Essick mixers, allowing straightforward replacement without machining or adaptation.
- Broad Mixer Compatibility — Fits WM90, WM70, EM90, and EM70 series mixers across multiple drum and engine configurations, including LF, S, and P variants.
- Preserves Belt Alignment — Correct pulley sizing keeps the drive belt running true, preventing premature belt wear, slippage, and uneven drum loading during extended mixing cycles.
- OEM Part Number Accuracy — Ordering by part number EM901074 confirms you receive the exact component specified for your machine, eliminating guesswork when sourcing mixer drive components.
The small pulley is a core component in the belt-drive system of Whiteman and Essick plaster and mortar mixers. It transmits engine power to the drum via a drive belt, with its diameter determining the speed ratio between the engine output and the drum. When this pulley becomes worn, cracked, or damaged, the drive belt can slip or run misaligned, resulting in reduced drum speed, uneven mixing, or complete loss of drum rotation. Replacing a worn small pulley with a correctly sized OEM part restores full drive efficiency and protects the belt and surrounding drive components from accelerated wear.
