Shop tools and tool sizes are identified through the section when applicable and all necessary dimensions, angles, and surface finishes are specified.

WHEN SHOULD AN ALTERNATIVE REPAIR BE PERFORMED?
These procedures do provide an alternative to replacement of major engine components. Local machine shop expertise is the first criterion. Beyond the technical requirements, availability, price and equipment down time are the considerations that will influence the decision.

INSPECTION
The procedures assume the component was inspected and the discrepancy noted during repair or overhaul. Only those inspection requirements directly related to the alternative repair procedure are provided.

FOLLOW ALL SAFETY INSTRUCTIONS NOTED IN THE PROCEDURES
Follow the manufacturer's recommendations for cleaning solvents and other substances used during the repair of the engine. Also, be sure to use good safety practices with tools and equipment.

FOLLOW THE CLEANING INSTRUCTIONS SPECIFIED IN THE PROCEDURES
After completing the repair, make sure all machining debris is removed and that the part is thoroughly cleaned.

PERFORM THE INSPECTIONS SPECIFIED IN THE PROCEDURES
