The Multiquip 13102ZC0003 Piston OS 0.25 Optional is a genuine OEM oversize piston designed for MC3H concrete mixers, MC3SE portable mixers, and C-4 walk-behind trowels. As an official Multiquip OEM component, it meets the exact tolerances and material specifications required for the engines fitted to these machines. This 0.25 mm oversize piston is intended for use during engine rebuilds when cylinder bores have been honed or re-bored to the corresponding oversize dimension. Sourced directly through authorized Multiquip distribution, this part ensures a proper fit for MC3H, MC3SE, and C-4 applications without compromise.
Key Features
- OEM Oversize Specification — Manufactured to the exact 0.25 mm oversize dimension required for correctly bored cylinders, ensuring the ring seal and compression integrity the engine depends on.
- Genuine Multiquip Component — Produced to OEM material and hardness standards, delivering the thermal resistance and wear characteristics expected from an original engine piston.
- Engine Rebuild Application — Designed specifically for installation during a bore-and-hone engine overhaul, pairing correctly with matching oversize rings and a freshly prepared cylinder wall.
- Broad Model Coverage — Fits MC3H concrete mixers, MC3SE portable mixers, and C-4 walk-behind trowels, making it a practical stock item for service operations running multiple machine types.
- Restored Compression Performance — A worn or undersized piston allows blow-by past the rings, robbing the engine of power and increasing oil consumption; installing the correct oversize piston restores full compression and clean combustion.
The piston is the central reciprocating component inside the engine cylinder. It transfers the force of combustion to the connecting rod and crankshaft, converting burning fuel into rotational power that drives the machine. Over time, cylinder walls and piston skirts wear, increasing clearance and allowing combustion gases to bypass the rings — a condition known as blow-by — which reduces power output, increases fuel and oil consumption, and can eventually cause hard starting or engine failure. When a cylinder is re-bored to remove wear, an oversize piston like the part is required to restore the correct bore-to-piston clearance and return the engine to full operating condition.
