Multiquip 11012H7200 Cylinder Liner 400

The Multiquip 11012H7200 Cylinder Liner 400 is a genuine OEM component designed for C30HDNI, C30HDN, C30HDNI Zenith, and C30HDNI Precision Mayco concrete pumps. As a direct OEM replacement, 11012H7200 is manufactured to the same specifications as the original part, ensuring correct installation and a proper bore fit within the engine block. This liner is the right choice when restoring engine integrity on your C30HDN or C30HDNI unit and keeping it performing at full output.

Key Features

• Genuine OEM Bore Integrity — Manufactured to exact original bore dimensions, ensuring correct piston-to-wall clearance and consistent compression across the engine.
• Drop-In Engine Block Fit — Engineered to seat directly into the engine block of C30HDNI and C30HDN concrete pumps with no machining or custom fitting required.
• Broad Pump Family Coverage — Compatible with C30HDNI, C30HDN, C30HDNI Zenith, and C30HDNI Precision Mayco concrete pump models.
• Restores Full Compression and Power Output — A worn or scored cylinder liner causes compression loss, increased oil consumption, and reduced pumping performance; replacing it restores the engine to proper operating condition.
• Fuel System Compatibility — Sourced to match both Zenith and Precision fuel injection variants of the C30HDNI, ensuring the correct liner specification for your specific engine configuration.

A cylinder liner is a precision-machined sleeve that forms the inner wall of the engine cylinder, providing the surface against which the piston rings seal and travel. It contains combustion pressure, manages heat transfer to the engine block, and directly determines how well the engine maintains compression. When a cylinder liner becomes worn, scored, or cracked, the engine loses compression, burns oil, and delivers reduced power — on a concrete pump, that means inconsistent output pressure and potential pump failure on the job. Replacing the liner with a genuine OEM part like the Multiquip 11012H7200 restores the engine's bore geometry and gets the pump back to full working capacity.
