FAQ

Q1: Is this cylinder block a complete assembly or just a bare block?
A1: This is a bare cylinder block assembly. It includes the block casting itself but does not include internal components such as pistons, liners, crankshaft, camshaft, or bearings. It is intended for rebuilders or mechanics who will install their own internal parts.

Q2: Will this block fit my Doosan DH220 excavator?
A2: The Doosan DH220 excavator commonly uses the DE12 engine. However, there are variations (e.g., DE12T with turbo). This cylinder block is designed for the DE12 series. We strongly recommend checking your engine serial number or old part number to confirm compatibility, as minor design changes occurred over the production years.

Q3: What is the recommended maintenance after installing a new cylinder block?
A3: After installation, it is critical to follow a proper break-in procedure. Use high-quality engine oil and a new oil filter. Run the engine at varying RPMs (avoid prolonged idling) for the first 50 hours. After the break-in period, perform an oil change and re-torque the cylinder head bolts as per the engine service manual. Regular oil changes and coolant maintenance are vital for long block life.
