The Multiquip 22165M5610 Carbon Point Assembly is a genuine OEM replacement designed for C30HDNI and C30HDN series Mayco concrete pumps, including the C30HDNI Precision and C30HDNI Zenith variants. As a factory-sourced component, it meets the original design specifications for the ignition system, ensuring dependable operation across the supported pump lineup. This part is sold by DHS Equipment and ships as a direct OEM replacement — no guesswork on compatibility when you reference part number 22165M5610.
Key Features
- Genuine OEM Carbon Contact Grade — carbon material matched to original ignition spec, maintaining proper contact resistance and arc timing critical to pump engine performance.
- Drop-In Distributor Fit — engineered to install directly into the distributor assembly of supported models without modification to the mounting points or rotor interface.
- Broad C30HDN Family Coverage — confirmed fitment for C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith concrete pump models.
- Consistent Spark Timing — a worn or pitted contact point causes misfires, hard starts, and erratic engine behavior; a fresh OEM-spec carbon point restores clean ignition timing and smooth pump operation.
- Ignition System Integrity — correct contact gap and carbon composition are essential to fuel system safety; using an OEM-matched point assembly reduces the risk of timing drift that can lead to backfire or uncontrolled combustion events.
The carbon point assembly is a precision ignition component housed inside the distributor of the engine powering your concrete pump. It opens and closes the primary ignition circuit at precisely timed intervals to trigger the spark plug and fire each cylinder. Over time, the carbon contact surface wears down or pits from repeated arcing, causing the ignition timing to drift, the engine to misfire, or the machine to become difficult to start. Replacing the point assembly with a correct OEM part restores the original contact geometry and ensures the ignition system fires cleanly and consistently under load.
