FAQ

Q: Will this HX35W fit my Cummins 6BT engine without modification?

A: Yes, this is a direct bolt-on replacement for the original Holset HX35W turbocharger. It matches the standard T3/T4 turbine inlet flange and the 4-bolt compressor outlet. However, you must check the oil drain flange orientation and wastegate actuator linkage position, as these can vary slightly between industrial (Komatsu) and automotive (Dodge) applications. We recommend comparing the “clocking” of the compressor housing with your old unit.

Q: What maintenance is required after installing this turbo?

A: Proper break-in is essential. After installation, run the engine at idle for 2-3 minutes to ensure oil pressure reaches the turbo bearing. Do not immediately rev the engine. Check for oil or air leaks at all connections. We recommend changing the engine oil and filter at the time of installation to prevent contamination of the new turbo bearings. Always allow the turbo to cool down by idling for 1-2 minutes before shutting off the engine after heavy use.

Q: What are the signs of a failing turbocharger on my Komatsu PC220-7?

A: Common symptoms include: 1) Loss of engine power and black smoke under load (insufficient boost). 2) Whining or screeching noise from the turbo area (worn bearings or damaged impeller). 3) Excessive oil consumption and blue smoke from the exhaust (oil seal failure). 4) Excessive shaft play. If you notice any of these, immediately inspect the turbo for damage to prevent debris from entering the engine’s intake system.
