FAQ

Q1: How do I confirm this cylinder block fits my Komatsu engine?
A: First, locate the part number on your existing cylinder block. It should match one of the following: 6204-21-1102, 6204-21-1503, or 6205-23-1300. Also, verify your engine model is a Komatsu 4D95. If you are unsure, please contact our support team with your engine serial number and machine model for cross-referencing.

Q2: What is included in the video outgoing inspection?
A: Before your order is shipped, we will provide a short video showing the actual cylinder block being inspected. This includes visual checks for casting defects, dimensional verification of critical mounting surfaces, and confirmation of part number markings. This ensures you receive exactly what you ordered.

Q3: What maintenance is recommended after installing a new cylinder block?
A: After installation, we recommend a break-in period of 50 hours at moderate load. During this time, check for coolant and oil leaks daily. Use high-quality diesel engine oil and coolant. Torque all cylinder head bolts and main bearing caps to the manufacturer’s specifications. A full engine tune-up (injectors, fuel pump, and valve clearance) is also advised after the break-in period to ensure optimal performance and longevity.
