The Honda 13102-ZF6-000 is a genuine OEM Piston (0.25) designed for GXV390 vertical shaft engines and the Honda equipment they power, including H2013, H2113, H3011, H3013, H4013, H5013, HRC7013, and RT5000 models. As a factory-sourced oversize piston, this component is matched to Honda's own engineering tolerances for the GXV390 bore — the (0.25) designation indicates a 0.25 mm oversize intended for engines with a lightly re-bored cylinder. Because this part carries a size qualifier and spans multiple machines, buyers should confirm the oversize specification matches their engine's actual bore condition before ordering.
Key Features
- OEM Bore Accuracy — manufactured to Honda's oversize specification, ensuring the correct piston-to-wall clearance for a properly re-bored GXV390 cylinder
- Oversize Variant — Confirm Before Ordering — the (0.25) designation is a 0.25 mm oversize; this piston is for engines whose cylinder has been bored to match, not a standard-bore replacement
- Broad Fitment Across Honda Equipment — listed for GXV390 vertical shaft engines as fitted in the H2013, H2113, H3011, H3013, H4013, H5013, HRC7013, and RT5000; check your serial number against the fitment table to confirm the correct part for your unit
- Restored Compression and Oil Control — a correctly sized oversize piston re-establishes proper ring seal against the cylinder wall, recovering compression and controlling oil consumption in a worn or damaged engine
The piston is the reciprocating heart of the GXV390 engine, traveling up and down within the cylinder bore to compress the air-fuel charge and transfer combustion energy to the crankshaft via the connecting rod. Piston rings seated against the cylinder wall are responsible for sealing combustion pressure above the piston and metering the oil film below it. When a cylinder bore is worn or scored beyond standard tolerances, it is re-bored to a slightly larger diameter and an oversize piston — such as this (0.25) unit — is fitted so that the correct running clearance is restored. Without the proper fit, compression leaks past the rings, oil consumption rises, and power output falls.
