The Multiquip 13104ZE3W00 is a genuine OEM Piston (0.75) GX340K1 designed for GA6HZ gasoline-powered generators, MVH304GSB heavy-duty reversible plate compactors, and GAW180HE, GAW180HE1, and GAW180HEA arc welders. As a direct Multiquip OEM component, this 0.75 oversize piston is manufactured to the exact dimensions required by the GX340K1 engine platform, ensuring a proper bore fit without guesswork. Confirm your engine model and bore size before ordering to ensure this oversize specification matches your engine's current condition.
Key Features
- Oversize OEM Piston Accuracy — Manufactured to the 0.75 oversize specification for the GX340K1 engine, matching the bore dimensions required after a standard oversize hone or rebuild.
- Genuine Multiquip OEM Component — Sourced directly from Multiquip, this piston meets the original material grade and dimensional tolerances specified for the GX340K1 engine platform.
- Direct Engine Rebuild Fitment — Engineered to drop into GX340K1-powered equipment including the GA6HZ, MVH304GSB, and GAW180HE series with correct ring land geometry and pin bore alignment.
- Protects Compression and Engine Output — A correctly sized oversize piston restores proper cylinder sealing and compression, enabling the engine to deliver its rated power to the machine's working components.
- Prevents Oil Consumption and Blow-By — A worn or incorrectly sized piston allows combustion gases and oil to bypass the rings; this OEM oversize piston eliminates that gap when paired with the appropriate bore size.
The piston is the reciprocating component inside the engine cylinder that transfers combustion energy to the crankshaft via the connecting rod. In a GX340K1 engine, the piston must seal precisely against the cylinder bore to maintain compression and prevent oil from entering the combustion chamber. An oversize piston — in this case the 0.75 specification — is used when the original cylinder bore has been machined or honed to a larger diameter during an engine rebuild. When a piston wears beyond acceptable tolerances, symptoms include loss of power, excessive oil consumption, blue exhaust smoke, and difficulty starting; replacing it with the correct oversize component restores the engine to proper operating condition.
