CONTROL VALVE UPPER BODY
DISASSEMBLY
1. Remove valves at retainer plates.
- Do not use a magnetic "hand".
a. Use a screwdriver to remove retainer plates.
b. Remove retainer plates while holding spring, plugs and sleeves.
- Remove plug slowly to prevent internal parts from jumping out.
c. Place mating surface of valve face down, and remove internal parts.
- If a valve is hard to remove, place valve body face down and lightly tap it with a soft hammer.
- Be careful not to drop or damage valves and sleeves.
INSPECTION
Valve Spring
- Measure free length and outer diameter of each valve spring. Also check for damage or deformation.
Inspection standard: Refer to image.
