FAQ

Q1: Will this turbocharger fit my Cummins QSB5.9 engine in a Case excavator?
This HX35W turbocharger is designed for the Cummins QSB5.9 engine platform commonly used in Case, New Holland, and other heavy equipment. However, mounting brackets, oil lines, and actuator configurations can vary by equipment manufacturer. We recommend comparing your existing turbocharger’s part number (3960454 or 4033579) and physical dimensions before ordering.

Q2: What maintenance is required before installation?
Prior to installation, always inspect and clean the engine’s oil supply line to ensure no debris reaches the new turbocharger bearings. Pre-lubricate the turbo by adding clean engine oil to the oil inlet port and rotating the compressor wheel by hand. Replace the oil filter and use fresh, high-quality diesel engine oil meeting Cummins CES 20074 or API CJ-4 specifications.

Q3: How can I verify this is a new unit and not a remanufactured one?
This product is sold as a 100% new turbocharger. You can verify by checking for the absence of weld marks, re-stamped serial numbers, or signs of previous use on the turbine housing. The unit will be sealed in original packaging with a protective coating on the compressor wheel. A machinery test report confirming new unit status is available upon request.
