FAQ

Q1: Is this cylinder block a direct fit for my Komatsu PC300-8 excavator?
A: This block is specifically designed for the 6D114 engine used in the PC300-8 series. However, we recommend verifying your engine serial number and comparing with the OEM part number 8-98023-526-0 to ensure exact compatibility. Variations exist between model years and regional specifications.

Q2: What is the weight of this cylinder block, and how should it be handled during installation?
A: The block weighs approximately 80 kg (176 lbs). Due to its weight and precision nature, it should be handled using appropriate lifting equipment (e.g., engine hoist or crane). Always follow the manufacturer’s service manual for proper installation procedures to avoid damage to sealing surfaces or internal threads.

Q3: Does this cylinder block come with main bearing caps or other internal components?
A: This listing is for the cylinder block casting only. Main bearing caps, cylinder liners, pistons, and other internal components are sold separately. Please consult our product catalog or contact us for a complete engine overhaul kit if needed.
