The Multiquip EM14314 is a genuine OEM Pulley Bushing designed for the C30HD series cycloidal-driven concrete pumps, including C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith models. As an authentic Multiquip replacement component, EM14314 ensures correct dimensional fit within the drive pulley assembly — no guesswork on sizing or compatibility. Sourced directly through authorized channels, this bushing meets the same specifications as the part originally installed at the factory. If your C30HD-series pump is showing signs of pulley slippage, excessive vibration, or drive system wear, replacing the Pulley Bushing with the correct OEM part is a straightforward first step toward restoring full pump output.
Key Features
- Precision-Matched OEM Tolerancing — Manufactured to exact bore and outer diameter specifications, ensuring proper pulley seating and consistent torque transfer within the C30HD drive system.
- Direct Drop-In Replacement — Engineered to seat into the existing pulley assembly of C30HD-series concrete pumps without rework or shimming.
- Broad C30HD Series Coverage — Confirmed fitment across C30HD, C30HDG, C30HDZ, C30HDGA, C30HDN, C30HDNI, C30HDNI Precision, and C30HDNI Zenith Mayco concrete pump variants.
- Protects the Drive System — A correctly fitted bushing keeps the pulley centered and load-bearing surfaces properly aligned, preventing accelerated wear on belts, shafts, and adjacent drive components.
- Genuine Multiquip OEM Part — Supplied under part number EM14314, this is an authentic component backed by Multiquip's parts program — not a generic substitute.
The Pulley Bushing is a precision fit component that locates and secures the drive pulley onto its shaft within the concrete pump's power transmission system. It fills the gap between the pulley bore and the shaft, transferring rotational force while keeping the pulley from shifting under load. When this bushing wears or becomes damaged, the pulley can develop play on the shaft — leading to belt misalignment, vibration, uneven wear across the drive train, and ultimately a loss of pumping efficiency or a complete drive failure.
