The Multiquip 25857-002 is a genuine OEM CM-4EB Mixer Drive Pulley designed for the CM4EB concrete mixer. As a factory-sourced component, it is manufactured to the same specifications as the original part and drops directly into place without guesswork or modification. This pulley is confirmed to fit CM4EB series mixers, making it the straightforward choice when the original has worn, cracked, or failed.
Key Features
- Genuine OEM Pulley Geometry — Manufactured to exact original dimensions, ensuring correct belt seating, proper tension alignment, and consistent power transfer from the drive system.
- Direct-Fit for CM4EB Mixers — Engineered specifically for the CM4EB concrete mixer; mounts to the existing drive shaft with no adapter hardware required.
- Correct Belt Groove Profile — Groove angle and width match the OEM drive belt, preventing belt slippage, uneven wear, and premature belt failure.
- Restores Full Drum Speed and Torque — A worn or damaged drive pulley causes inconsistent drum rotation and loss of mixing efficiency; this replacement brings the drive system back to proper operating output.
- Sourced Through Authorized Multiquip Supply Chain — Genuine OEM part backed by Multiquip's parts program, so you get the correct component for your CM4EB the first time.
The drive pulley is a core element of the mixer's power transmission system. It connects to the engine's output via a drive belt and transfers rotational force to the drum, controlling both the speed and consistency of the mixing action. When the pulley wears down, cracks, or loses its groove profile, the drive belt loses traction, causing the drum to slip, slow, or stop responding correctly — which directly affects mix quality and cycle times. Replacing a damaged pulley with a correctly spec'd OEM unit restores reliable drum operation and protects the drive belt from accelerated wear.
