FAQ

Q1: Is this turbocharger a direct replacement for my Komatsu PC360-7?
A: Yes, this HX40W unit (part numbers 4038421/4090015/4089189) is a direct OEM replacement for the Komatsu PC360-7 excavator equipped with the Cummins 6CTAA engine. It is a bolt-on part; however, we always recommend verifying your engine serial number and old turbo part number to ensure a perfect match.

Q2: What maintenance is required before installing this new turbocharger?
A: To ensure longevity, you must prime the turbo with clean engine oil before starting. Also, it is critical to inspect and replace the engine oil, oil filter, and air filter. Check the oil supply line for blockages and the return line for restrictions to prevent premature bearing failure.

Q3: What should I do if the turbo is not building enough boost after installation?
A: Low boost pressure usually indicates a leak in the intake/charge air system or a faulty wastegate actuator. First, check all hose clamps and intercooler connections for leaks. If the system is sealed, test the wastegate actuator rod for proper movement and adjustment. Ensure the engine itself is not suffering from excessive blow-by.
