Installation Notes

• Confirm the turbo identification and compare supplied parts with the originals before assembly.
• Inspect shaft journals, wheels, bearing bores and seal grooves; new service parts cannot correct damaged or out-of-specification components.
• Correct oil supply, drainage, contamination and crankcase-pressure problems before reinstalling the turbo.
• Follow the applicable service procedure for assembly, clearances, fastener torque, lubrication and priming.
• Balancing the completed rotating assembly is recommended best practice.
