FAQ

Q1: Is this liner kit a direct fit for my Doosan DH300-7 excavator with a DE08 engine?
A: Yes, this kit (part number D1146 / OEM 65.02501-0228B) is specifically designed for the Doosan DE08 engine. It is the standard replacement for the DH300-7 model. We recommend checking your engine serial number to confirm the engine variant is DE08.

Q2: What is included in this “Liner Kit”? Does it include piston rings or gaskets?
A: This specific product listing is for the cylinder liners only. It does not typically include pistons, rings, or a full gasket set. For a complete engine rebuild, you may need to purchase a separate piston & ring set and an engine gasket kit. Please contact us for a complete overhaul kit if needed.

Q3: What is the recommended installation procedure for these liners?
A: Installation should be performed by a qualified diesel mechanic. The cylinder block bore must be cleaned and measured. The new liners should be installed with the correct interference fit. After installation, the liner height protrusion above the block deck must be checked to ensure proper cylinder head sealing. Always follow the engine manufacturer’s service manual for torque specifications and procedures.
