FAQ

1. Is this piston a direct fit for my Doosan DH220-7 excavator?

This piston is designed for the DB58 engine, which powers the DH220-7 model. It matches the OEM part number 65.02501-0416. We recommend checking your engine’s serial number and verifying the piston diameter (standard OEM size) against your current part to ensure 100% compatibility before installation.

2. What is included in the package? Do I need to buy rings separately?

The package includes one piston (65.02501-0416) only. Piston rings are typically sold separately or as part of a complete engine overhaul gasket set. We recommend purchasing matching piston rings from the same supplier to ensure correct ring groove fitment and end gap tolerances.

3. What maintenance steps should I take when replacing this piston?

When replacing the piston, always inspect the cylinder liner for wear or scoring. Clean the piston cooling jets and ensure proper lubrication during reassembly. After installation, follow the engine manufacturer’s break-in procedure, including a low-load run-in period, to allow the piston rings to seat correctly. Always use new gaskets and seals for the reassembly.
