FAQ

Q: Will this oil cooler side cover fit my Komatsu PC300-7 excavator?
A: This cover is specifically designed for the SAA6D114E-3 engine commonly installed in PC300-7 models. However, we recommend verifying your existing part number against OEM reference 6743-61-2111, 3974324, or 4936396. Engine serial number variations may affect compatibility, so cross-checking is always advised before ordering.

Q: What is the recommended installation procedure for this part?
A: Installation requires draining engine oil, removing the old side cover, cleaning the mating surface thoroughly, and installing the new cover with a fresh gasket (sold separately). Torque bolts to manufacturer specifications in a crisscross pattern to ensure even sealing. We recommend consulting the Komatsu service manual for your specific excavator model for detailed torque values and procedures.

Q: How can I confirm this is a 100% new part and not a refurbished unit?
A: This component is manufactured as 100% new, meaning no recycled materials or reconditioned components are used. The part surface will show clean machining marks without signs of prior wear or gasket residue. We provide video outgoing inspection documentation upon request to verify the new condition before shipment. The product packaging also clearly indicates “100% New” status.
