(All Models)

Clean all parts with solvent. Dry parts with compressed air. When disassembling upper or lower valve body, maintain parts in order for reassembly reference. Ensure each valve is kept with corresponding spring. For upper valve body exploded views, see Fig 1 and Fig 2. For lower valve body exploded views, See Fig 3-63.
Ensure all valve body oil passages are clear. Inspect valves for scoring or roughness. 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 check balls, pins, retainers, strainers and vibrating stopper is installed in appropriate locations. See Fig 5 or Fig 6.
