The Multiquip 13103Z5K000 is a genuine OEM Piston (0.50 OS) designed for GX270UT2SMXC-powered equipment including the GA3.6HR generator and MVH208GH and MVH308GH reversible plate compactors. As a factory-authorized oversize piston, the 13103Z5K000 is the correct service component when the cylinder bore has been honed or reconditioned to the 0.50mm oversize specification. This part ships direct from authorized Multiquip inventory, so you can be confident it matches the original component your machine was built with. Verify your engine code and bore measurement before ordering to confirm the oversize grade is correct for your application.
Key Features
- Genuine OEM Oversize Specification — Manufactured to the exact 0.50mm oversize dimension required after cylinder bore reconditioning, ensuring correct wall clearance and ring seal for the GX270UT2SMXC engine.
- Drop-In Engine Rebuild Component — Engineered as a direct service replacement that installs with standard Honda GX270-series piston pins and rings; no custom machining or adaptation required beyond the matched bore hone.
- Confirmed Fitment for GA3.6HR, MVH208GH, and MVH308GH — Verified for use across Multiquip's GA3.6HR gasoline generator and MVH208GH and MVH308GH heavy-duty reversible plate compactors sharing the GX270UT2SMXC engine configuration.
- Restores Full Compression and Power Output — A correctly sized oversize piston eliminates the blow-by caused by a worn or scored bore, returning the engine to full compression, proper fuel combustion, and rated power output.
- Fuel System and Engine Safety Compliance — Using the correct oversize grade prevents improper piston-to-wall clearance, which can cause piston seizure, accelerated wear, or uncontrolled engine failure during operation.
A piston is the reciprocating component inside the engine cylinder that transfers combustion force to the crankshaft via the connecting rod, driving the machine's output. Over time, cylinder walls and piston skirts can wear, increasing clearance and allowing combustion gases to bypass the rings — a condition known as blow-by — which reduces power, increases oil consumption, and can lead to engine failure. When the cylinder bore is reconditioned by honing to an oversize diameter, an oversize piston such as the 13103Z5K000 at the 0.50mm grade is required to restore the correct fit and compression seal, bringing the engine back to full working condition.
