NOTE

All components not discarded during disassembly must be thoroughly inspected according to

the following procedures to determine if they can be reused in rebuilding the turbo.

Some defects you may discover during inspection can be repaired (WP 0011 00); however,

parts that are worn or damaged beyond repair must be replaced with new parts.

Wear standards for turbo components are provided within the applicable inspection

procedures. Use appropriate precision measuring instruments when checking for wear. When

measuring inside or outside diameters, always take two measurements approximately 90

degrees apart to allow for possible out--of--round condition.

When inspecting for cracks, use a strong light and magnifying glass.
