The Multiquip 2105120500 Fan and Pump Pulley is a genuine OEM component designed for C30HDNI and C30HDN series Mayco concrete pumps, including C30HDNI Precision and C30HDNI Zenith configurations. As a direct OEM replacement, this pulley is manufactured to the same specifications as the original, ensuring correct belt engagement and proper drive alignment right out of the box. Sourced directly through authorized Multiquip channels, the 2105120500 is the part number to reference when servicing C30HDN-family concrete pump units. DHS Equipment stocks genuine Multiquip parts so you can get your pump back in service without guesswork.
Key Features
- Genuine OEM Construction — Manufactured to original Multiquip tolerances for correct belt wrap angle and pulley diameter, critical to maintaining proper drive speed on the fan and pump circuit.
- Direct-Fit Replacement — Mounts to the same shaft position as the original, requiring no machining or adaptation during reinstallation.
- Confirmed Fitment — Compatible with C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith Mayco concrete pump models.
- Drive System Integrity — A correctly sized and seated pulley keeps belt tension consistent across both the cooling fan and hydraulic pump drives, protecting downstream components from premature wear.
- Fuel and Ignition System Safety — Proper pulley function on concrete pump drive systems prevents belt slippage that can lead to overheating or hydraulic pressure loss mid-pour.
The fan and pump pulley is a driven component in the belt drive system of the concrete pump, transferring rotational power from the engine to both the cooling fan and the hydraulic or water pump simultaneously. A worn, cracked, or improperly sized pulley causes belt slippage, uneven wear, and loss of flow or cooling capacity — issues that can bring a concrete pour to an unplanned stop. Replacing this pulley with a genuine OEM part like the Multiquip 2105120500 restores the correct drive ratio and belt contact surface, keeping both the fan and pump circuits running at their intended output.
