FAQ

Q1: Will this repair kit fit my 6BT engine?
This kit (Part 3545669) is designed for the turbocharger used on the 6BT and NTA855 engine series. It is not a direct engine part but a rebuild kit for the turbo unit itself. You must confirm that your turbocharger model is compatible with this kit. Common turbo models for these engines include the Holset H1C or HX35. Please check your turbocharger’s tag or casting number.

Q2: What is included in the kit, and what tools are needed for installation?
The kit typically includes a complete set of gaskets, seals (piston ring, oil seal), O-rings, and a thrust washer. Installation requires standard mechanic tools (wrenches, sockets), a torque wrench, and clean working conditions. It is strongly recommended to have the turbocharger professionally balanced after installing new parts, especially if the rotating assembly was disturbed.

Q3: How do I know if my turbocharger needs this repair kit?
Common signs include excessive oil consumption, blue or black smoke from the exhaust, a whistling or grinding noise from the turbo, or visible oil leaks around the turbocharger housing. A loss of engine power and increased exhaust temperature are also indicators of failing turbo seals or bearings. If you observe these symptoms, this rebuild kit is the correct solution for overhauling the unit.
