Description
Overview:
This Piston Assembly for Honda GX390 is a Non Genuine part designed as a reliable, cost‐effective replacement for worn components in the GX390 engine family, including common sets such as the EC5000 generator. The kit includes a standard‐size piston, piston rings, gudgeon (wrist) pin, and circlips, giving you the core parts needed for a routine top‐end refresh. The piston is typically aluminium alloy for strength and heat transfer, while the pin and rings are steel for durability and stable sealing. When fitted correctly to a serviceable, standard cylinder, it helps restore compression, reduce oil consumption, and support smooth running in heavy‐duty industrial and garden machinery powered by Honda GX390‐based engines.
Key Features:
- Non Genuine replacement engineered to suit Honda GX390 series
- Standard size for use with stock, in‐tolerance cylinder bores
- Aluminium alloy piston with steel gudgeon pin and wear‐resistant rings
- Complete kit: piston, ring set, pin, and circlips for a straightforward rebuild
- Helps restore compression and oil control when installed to spec
- Smooth running and reliable starting in day‐to‐day site and garden use
- Suitable for generators, pressure washers, pumps, mixers, and compactors using GX390
- Practical, affordable option for maintenance without compromising on fit
Typical Applications:
For refurbishing Honda GX390‐powered equipment such as site generators (e.g. EC5000), pressure washers, water pumps, plate compactors, cement mixers, chippers, and other machinery. Ideal when addressing loss of power, oil burning, or low compression due to ring or piston wear in standard‐bore engines.
