The Multiquip 25857-001 is a genuine OEM Driven Pulley CM4EB Mixer component designed for the CM4EB concrete mixer. As a direct OEM replacement, this pulley is manufactured to the same specifications as the original part, ensuring a correct, drop-in fit with no guesswork. Verified for the CM4EB, this part keeps your mixer's drive system operating as intended.
Key Features
- Genuine OEM Construction — Manufactured to exact original specifications, ensuring the pulley groove profile, bore dimensions, and material grade match the drive system requirements of the CM4EB Mixer.
- Direct-Fit Replacement — Engineered to mount and align in the same position as the original driven pulley, allowing straightforward installation without modifications to existing hardware or belt routing.
- CM4EB Mixer Fitment — Confirmed compatible with the Multiquip CM4EB concrete mixer; always cross-reference part number 25857-001 before ordering.
- Restores Belt Drive Performance — A worn or damaged driven pulley causes belt slippage, uneven drum rotation, and premature belt wear; replacing it with the correct OEM part restores consistent torque transfer to the drum.
- Durable Under Continuous Load — Built to withstand the sustained rotational loads and vibration common in mixer applications, supporting long service intervals between replacements.
The driven pulley is a core component of the belt drive system on the CM4EB Mixer. It receives rotational force transmitted through the drive belt from the engine-side pulley and transfers that motion to the drum, enabling the continuous turning action needed to mix concrete. When the driven pulley becomes worn, cracked, or out of round, the belt loses proper tension and tracking, leading to slippage, inconsistent drum speed, and accelerated wear on both the belt and surrounding drive components. Replacing it promptly with the correct part — Multiquip 25857-001 — restores smooth, efficient drum operation.
