Valve Body Assembly: Inspection
- Clean all parts in solvent. Dry with compressed air. Ensure all valve body passages are clear. Ensure strainers are not damaged or clogged. Inspect valves for scoring or roughness.
- Ensure valves slide freely in bores. Inspect valve springs for damage, squareness and collapsed coils. Measure spring free length. Replace spring if not within specification. See appropriate VALVE BODY SPRING SPECIFICATIONS table. Ensure valve body springs correspond with appropriate valve. Ensure retainers are installed in appropriate locations.
