The Multiquip 13103ZH9000 Piston (OS 0.50) (Optional) is a genuine OEM oversized piston designed for the engine assemblies powering MP2050E1, MP2050E3, MP2090HP, MP25E1, MP25E3, MP275E3, and MP2H masonry saws. As a direct Multiquip OEM component, 13103ZH9000 is manufactured to the same specifications as the original part, ensuring a correct fit within the engine bore when used as part of a planned engine rebuild or oversize reconditioning service. This optional oversized piston is intended for use when the cylinder bore has been honed or bored to accept the 0.50mm oversize dimension, restoring the engine to proper operating tolerances. Sourced directly through authorized distribution, this part is verified for compatibility across the MP-series masonry saw lineup listed above.
Key Features
- Genuine OEM Oversize Specification — Cast and machined to Multiquip's 0.50mm oversize dimension, matching the original bore reconditioning standard for these engine families.
- Engine Rebuild Ready — Designed for installation after cylinder honing or boring to OS 0.50, restoring correct piston-to-wall clearance and compression integrity.
- Broad MP-Series Compatibility — Confirmed fitment across MP2050E1, MP2050E3, MP2090HP, MP25E1, MP25E3, MP275E3, and MP2H masonry saws.
- Compression and Power Restoration — A correctly sized oversize piston seals the bore properly, recovering lost compression caused by cylinder wear and restoring full cutting power to the saw.
- Authorized OEM Sourcing — Supplied through authorized Multiquip distribution channels, ensuring you receive a verified, uncompromised component for a critical engine rebuild application.
A piston is one of the core reciprocating components inside an internal combustion engine, converting the force of combustion into the rotary motion that drives the saw blade. Over time and heavy use, cylinder walls and piston surfaces wear, reducing the tight clearance needed to maintain compression — leading to loss of power, increased oil consumption, and hard starting. An oversize piston, like the 13103ZH9000 at OS 0.50, is used during engine reconditioning when the cylinder bore has been machined slightly larger to remove wear damage; the oversized piston fills that larger bore correctly, restoring the engine's original performance characteristics rather than replacing the entire power unit.
