A: Please verify the engine model plate on your equipment. This block is specifically designed for the Komatsu 4D94, 4D94E, 4D94LE, and 4TNV94 diesel engines. If you have the engine serial number or a specific OEM part number, please contact our support team for cross-referencing before placing your order.

Q: What is included with the cylinder block upon delivery?

A: You will receive the bare cylinder block. It does not include internal components such as pistons, liners, crankshaft, or main bearing caps unless specified. Please ensure you have all necessary internal parts and gaskets for a complete engine rebuild.

Q: What is the recommended maintenance after installing a new cylinder block?

A: After installation, it is critical to follow the engine manufacturer’s break-in procedure. This typically includes running the engine at varying loads, checking torque on head bolts after initial heat cycles, and performing an early oil and filter change to remove any debris from the break-in process. Always use the recommended grade of engine oil.
