FAQ

Q1: How can I confirm this cylinder block fits my Komatsu PC200-8 excavator?
A: Please verify the engine model plate on your machine. If your excavator is equipped with a Cummins 6D107, SAA6D107, or QSB6.7 engine, and your original block part number matches one of the listed OEM numbers (5302096, 5405093, 4955412, 4991099, or 6754-21-1310), then this block is a direct fit. We recommend comparing the casting number on your old block for maximum accuracy.

Q2: Does this cylinder block come with main bearing caps and hardware?
A: This listing is for the cylinder block casting itself. Main bearing caps, bolts, and other internal hardware are typically not included unless specified. Please check the product packaging description or contact us for details on what is included in your specific order.

Q3: What is the expected lifespan of this aftermarket cylinder block compared to an OEM Komatsu part?
A: This block is manufactured to OEM size specifications using high-grade cast iron. With proper installation, correct torque procedures, and regular engine maintenance (including proper coolant and oil changes), it can provide a service life comparable to the original OEM block. The 6-month warranty covers any manufacturing defects.
