The Multiquip 13103ZE2W00 is a genuine OEM Piston OS 0.50 Optional designed for a wide range of Multiquip and Whiteman equipment including MC94P/S, MC94SK, MC94PK, MC64P/S, WM70S/P, R2000H, QP3TH, QP402H, GA3.6HA, and GA3.6HZ models. As a factory-sourced component, this oversize piston is engineered to Multiquip's exact specifications, ensuring proper fitment and correct dimensional tolerancing within the engine cylinder bore. This part is the right choice when an engine rebuild calls for an oversize replacement due to cylinder wear, providing a cost-effective path to restoring full engine performance across multiple Multiquip equipment families.
Key Features
- Oversize Bore Tolerancing — Machined to OS 0.50 specification, this piston compensates for cylinder wall wear and restores correct compression and clearance values in the engine bore.
- Genuine OEM Sourcing — Factory-produced to Multiquip's original engineering standards, ensuring dimensional accuracy critical to piston-to-wall fit and ring seal integrity.
- Broad Equipment Compatibility — Fits MC94P/S, MC94SK, MC94PK, MC64P/S, WM70S/P, R2000H, QP3TH, QP402H, GA3.6HA, and GA3.6HZ, making it a versatile rebuild component across concrete mixers, rollers, pumps, and generators.
- Engine Compression Restoration — A correctly fitted oversize piston seals the combustion chamber properly, restoring lost power output and preventing excessive oil consumption caused by a worn standard-size bore.
- Rebuild-Ready Component — Intended for use during a qualified engine overhaul when cylinder boring to OS 0.50 has been performed, slotting directly into the rebuild procedure without improvisation.
A piston is the reciprocating component inside the engine cylinder that transfers combustion energy to the crankshaft via the connecting rod. Over time, the cylinder bore and piston skirt can wear beyond the standard clearance tolerance, leading to poor compression, oil blow-by, and reduced engine power. An oversize piston — such as this OS 0.50 unit — is used after the cylinder has been professionally bored out to match, restoring the correct fit between piston and cylinder wall and bringing the engine back to full working condition.
