FAQ

Q: What is included in the Turbocharger Repair Kit 3545647?
A: This kit typically includes all the consumable wear parts required for a standard turbocharger rebuild. This commonly consists of a thrust bearing, journal bearings, piston ring, seal ring, O-rings, and a full set of gaskets. The exact contents are designed to match the OEM specification for the K19/KT19 series turbocharger.

Q: How do I know if this kit fits my specific turbocharger?
A: This kit is designed for the Holset turbochargers found on the K19, KT19, KTA19, and KTTA19 engines. To confirm fitment, please check the model plate on your turbocharger housing. The most common compatible models are Holset HX40, HX50, or similar. If your turbo part number is 3545647 or 3803257, this kit is the correct service part.

Q: What is the recommended maintenance interval for replacing this kit?
A: The replacement interval depends heavily on operating conditions and application. For heavy-duty applications in mining or construction, it is common practice to inspect and potentially rebuild the turbocharger every 10,000 to 20,000 hours of operation, or during a major engine overhaul. Signs of needed replacement include excessive oil consumption, visible oil leaks from the turbo, or unusual whistling noises from the intake. Always consult your engine’s service manual for specific recommendations.
