The Multiquip 502210 Upper Pulley is a genuine OEM component designed for Multiquip, Essick, Whiteman, and STOW 9-cubic-foot concrete mixer models including the EC-92P, EC-92S, MC-92P, MC-92S, WC-92P, WC-92S, and CMS-9. As a direct OEM part, 502210 is manufactured to the same specifications as the original, ensuring a correct installation with no guesswork on fitment. If your mixer's drive belt is slipping, misaligned, or showing uneven wear, the upper pulley is a common point of failure and a critical part to inspect and replace. DHS Equipment supplies this part as an authorized Multiquip OEM replacement, so you can order with confidence knowing you're getting the right part for your machine.
Key Features
- Genuine OEM Construction — Manufactured to original tolerances, ensuring correct belt engagement and groove profile for the drum drive system.

- Restores Drive System Efficiency — A worn or damaged upper pulley causes belt slip, uneven drum rotation, and accelerated belt wear; replacing it brings the drive system back to proper operating condition.
- Verified Part Number — Part number this part is confirmed against Multiquip OEM documentation, giving you confidence you are sourcing the correct component for your mixer.
The upper pulley is a key element of the concrete mixer's belt-drive system, working in conjunction with the lower pulley and drive belt to transfer power from the engine to the rotating drum. It maintains proper belt tension and alignment so the drum turns consistently and at the correct speed throughout the mixing cycle. When the upper pulley wears, cracks, or becomes damaged, it disrupts belt tracking, causes slippage, and can lead to premature belt failure — ultimately preventing the mixer from achieving a thorough, uniform mix.
