The Multiquip 12010G3462 Piston Set with Pin Standard is a genuine OEM replacement designed for C30HDNI, C30HDN, C30HDNI Precision, and C30HDN Zenith series Mayco concrete pumps. As a direct OEM part, it is manufactured to the same specifications as the original, ensuring correct fit and consistent pumping performance across compatible C30 cycloidal-drive pump models. DHS Equipment sources this part directly through authorized Multiquip distribution channels, so you can order with confidence that you are receiving the correct assembly for your machine.
Key Features
- Genuine OEM Piston Tolerancing — Manufactured to OEM bore and pin dimensions, maintaining proper compression and seal contact within the pump cylinder.
- Complete Set with Pin Included — Supplied as a full piston and wrist pin assembly, so you have every component needed for a complete piston replacement in a single order.
- Standard Bore Specification — Standard sizing fits unworn or freshly honed cylinders, making this the correct choice for routine overhaul and preventive maintenance rebuilds.
- Confirmed Fitment for C30 Pump Series — Verified for C30HDNI, C30HDN, C30HDNI Precision, and C30HDN Zenith Mayco concrete pump models.
- Restored Pumping Pressure and Output — A worn piston set causes pressure loss, inconsistent concrete flow, and increased wear on surrounding components; replacing with a correctly sized OEM set restores rated output and protects the cylinder walls.
The piston set is the core reciprocating component inside a concrete pump's cylinder assembly. As the piston strokes back and forth, it draws concrete mix into the cylinder and then forces it through the discharge line at controlled pressure. Over time, the piston and wrist pin wear against the cylinder bore and connecting rod, leading to loss of pumping pressure, uneven material flow, and potential damage to the cylinder itself. Replacing a worn piston set with a correctly sized OEM assembly restores the pump's rated output and prevents secondary wear that can escalate repair costs significantly.
