This Reuse and Salvage Guideline contains the necessary information in order to allow a dealer to establish a parts reusability program. Reuse and salvage information enables Caterpillar Dealers and customers to benefit from cost reductions. Every effort has been made in order to provide the most current information that is known to Caterpillar. Continuing improvement and advancement of product design might have caused changes to your product which are not included in this publication. This Reuse and Salvage Guideline must be used with the latest technical information that is available from Caterpillar.For additional information about this guideline, consult Repair Process Engineering of the Marketing & Product Support Division at 1 (309) 675-5434.Summary
These instructions give failure modes of valves for engines using the basic principles of wear and fracture to determine the most probable root cause of failure. This guide should be used with the additional documents in the reference section to define the reusability of valves. References

Straight Edge Fretting
Fretting indicates repeated movement in a tight joint. Movement should not occur in the retaining area of the valve. Typically fretting is a result of the following items.
Loose valve lash
Engine over speed
Sticking valves in guides
Broken valve spring
Illustration 2 g01183438
FrettingFractures will typically be brittle and/or fractures will be low cyclic fatigue due to an overloading in shock that is caused by excess velocities in seating of loose valve lash.Beach marks are clearly evident in the photo below indicating cyclic overloads.
Illustration 3 g01183441
Beach MarksWear at the valve stems and/or valve bridges' interface may also be present.
Illustration 4 g01183442
Wear on valve stem and/or bridgeTight Lash
Valves may not display oil degradation, adhesive wear, or fretting if valve lash was too tight. Also if valve lash was too tight valve heads may show repeated contact with the piston. Tight lash may affect only one valve in a cylinder or all the valves within the engine.
Illustration 5 g01183449
Piston contact on valveIf the valve lash is too tight, compression and combustion gases may leak past the valve face and the valve seat. This will cause the visual signs of gas to be left behind on the valves' face and valves' fillet. The gas leaks may overheat the valve head and the valve stem which will cause
