Illustration 1 g03856854
The top deck surface may have irregular patterns that do not affect the sealing performance.
Illustration 2 g03856855
The surfaces may have swipe marks from machining, but still meet the surface finish specifications.
Illustration 3 g03856856
The liner lower bore may have minor corrosion, but the remaining surface is adequate for sealing due to the use of three o-rings on liners.These areas are inspected and passed based on criteria validated on Reman engines.
