The Multiquip 13021H8900 Crank Sprocket is a genuine OEM component designed for C30HDNI and C30HDN series Mayco concrete pumps, including C30HDNI Precision and C30HDNI Zenith variants. As an authentic Multiquip OEM part, the 13021H8900 is manufactured to the same specifications as the original, ensuring a direct, accurate installation without guesswork. Sourced through DHS Equipment, this crank sprocket is the correct replacement for operators looking to restore full pumping performance on compatible Mayco concrete pump models.
Key Features
- Genuine OEM Tooth Geometry — Manufactured to exact original tooth profile specifications, ensuring correct chain engagement and smooth power transfer from the crankshaft.
- Direct Drop-In Fitment — Engineered to match the original mounting interface on C30HDNI, C30HDN, C30HDNI Precision, and C30HDNI Zenith concrete pumps.
- Confirmed Compatibility — Verified fitment across the C30HDN and C30HDNI Mayco concrete pump family, including Precision and Zenith engine configurations.
- Sustained Pump Cycle Integrity — A correctly functioning crank sprocket maintains consistent drive chain timing, supporting steady, uninterrupted concrete output during pumping operations.
- OEM Durability Standard — Produced from materials meeting Multiquip's original hardness and wear-resistance requirements for high-cycle concrete pump drive systems.
The crank sprocket is a core component of the concrete pump's drive system, transmitting rotational force from the crankshaft to the drive chain that powers the pumping mechanism. It works in constant mesh with the drive chain under significant load, and over time the sprocket teeth wear down, leading to chain slippage, inconsistent pump strokes, or complete drive failure. Replacing a worn crank sprocket with a genuine OEM part like the Multiquip 13021H8900 restores the correct drive ratio and chain tension, keeping the pump cycling efficiently and protecting the surrounding drivetrain components from accelerated wear.
