INSPECTION
The reason for parts inspection is to find out which parts can be used and which must be replaced. Specifications and
tolerances are given in this manual, but sometimes you, the inspector, must make the decision of which parts should be
replaced.
To find out if you can use a part that is otherwise in good condition, check the clearance between mating surfaces. If
clearance is within tolerance, reinstall part.
Carefully look at all machined surfaces and polished areas. Use a strong light to shine across polished surfaces to check
for score marks, cracks, breaks, and wear.
Inspect gears for cracked, nicked, and chipped teeth. Look for metal-to-metal abrasion, pitting, and wear. When a gear is
found to be defective, replace it and its mating gear.
SERVICE REPLACEMENT KITS
Many service replacement parts are available in various undersize and/or oversize, as well as standard sizes. Also, service
kits for reconditioning certain parts and service sets which include all of the parts necessary to complete a task are
available (for example, steering shaft universal joint kit).
TAGGING PARTS
Use cardboard tags with wire fasteners (item 29, appendix C) to identify all electrical wires: hydraulic, fuel, oil, and coolant
lines, and any other parts which may be hard to identify or place later. Fasten tags to parts during removal by wrapping
wire fasteners around or through parts and twisting ends together. Position tags to be out of the way during cleaning,
inspection, and repair. Mark tags with a pencil, pen, or felt-tip marker.
