The Multiquip 30411H5001 Engine Rear Plate is a genuine OEM component designed for Mayco concrete pump models C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith. As a direct factory replacement, this plate restores the correct structural interface between the engine and the pump housing, ensuring proper alignment and secure mounting. Sourced directly from Multiquip, part number 30411H5001 meets the exact specifications of the original component installed at the factory. If you are servicing or rebuilding a C30HDNI or C30HDN series concrete pump, this is the correct OEM plate for the job.
Key Features
- Genuine OEM Construction — Manufactured to the exact material grade and dimensional tolerances of the original engine rear plate, ensuring correct load-bearing performance at the engine-to-pump interface.
- Direct Bolt-On Replacement — Matches the original mounting pattern and hardware configuration of C30HDNI and C30HDN series concrete pumps for a straightforward swap during service or rebuild.
- Broad C30HD Series Compatibility — Confirmed fitment across C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith Mayco concrete pump variants.
- Maintains Engine Alignment — A worn or damaged rear plate can allow engine shift and misalignment, leading to accelerated wear on drive components; replacing it promptly protects the broader drivetrain.
- Structural Integrity Under Load — Concrete pumps operate under sustained mechanical stress; this OEM plate is built to handle the continuous vibration and torque loads typical of cycloidal-drive pump operation.
The engine rear plate is a structural mounting component that secures the engine to the rear of the pump casing, maintaining precise alignment between the power source and the drive mechanism. On cycloidal concrete pumps like the C30HD series, correct engine positioning is critical — any movement or play at this interface can cause uneven wear on drive gears, bearings, and seals throughout the pump assembly. When the rear plate cracks, warps, or develops damaged mounting points, engine vibration increases and internal components are placed under stress they are not designed to absorb.
