Valve Body Assembly: Inspection

WARNING: This page is about a different variant/trim than selected.

Clean all parts with solvent. Dry parts with compressed air. Ensure all valve body oil passages are clear. Inspect valves for scoring or roughness. See Fig 1 and Fig 2 . Inspect valve springs for damage, squareness, rust and collapsed coils. Measure spring free length and outer diameter.
Replace spring if not within specification. See appropriate VALVE BODY SPRING SPECIFICATIONS table. Ensure valve body springs correspond with appropriate valve. Ensure keys are installed in appropriate locations. See appropriate VALVE BODY KEY SPECIFICATIONS table.
