The Honda 13101-Z9M-000 Piston is a genuine OEM replacement designed for GCV170 and GCV200 vertical shaft engines and the HRX217 lawn mower. As a Honda OEM component, this piston is manufactured to the exact dimensions the engine was designed around, ensuring proper bore clearance and ring land geometry right out of the box. Confirm your machine's serial number against the fitment table before ordering — Honda supersedes parts at serial breaks, and verifying now saves time later.
Key Features
- Exact OEM Dimensions — cast to Honda's original bore diameter and compression height specifications, so ring seating and combustion geometry are correct from the first start
- Direct Drop-In Replacement — designed as a direct replacement for GCV170 and GCV200 vertical shaft engines and the HRX217 lawn mower; no machining or adaptation required
- Check Your Serial Number — Honda updates part numbers at production breaks, so match your machine's serial number to the fitment table to confirm this is the right piston for your unit
- Restores Compression and Power — a worn piston allows blow-by past the rings, causing hard starts, loss of power, and excessive oil consumption; this replacement brings bore sealing back to spec
The piston is the reciprocating heart of the engine's power stroke. Fuel and air ignite above it, forcing it down the cylinder bore and converting combustion pressure into crankshaft rotation. The piston also works with its rings to seal combustion gases above and control oil below — when the piston or its ring lands wear, compression drops, oil burns off, and the engine loses the power needed to drive the mower blade. Replacing a worn piston restores the tight bore seal that keeps the GCV170, GCV200, and HRX217 running at full output.
