Regulator Valve Body Disassembly, Inspection, and Reassembly

Regulator Valve Body Disassembly, Inspection, and Reassembly

1. Clean all parts thoroughly in solvent, and dry them with compressed air. Blow out all passages.

2. Inspect the regulator valve body for scoring and damage.

3. Hold the regulator spring cap in place while removing the stop bolt. The regulator spring cap is spring loaded. Once the stop bolt is removed, release the spring cap slowly so it does not pop out.

4. Check all valves for free movement. If any fail to slide freely, do the valve body repair procedure Valve Body Repair.

5. Coat all parts with ATF during assembly.

6. Align the hole in the regulator spring cap with the stop bolt hole, then press the spring cap into the valve body, and tighten the stop bolt.

7. Install the servo valve with a new O-ring, and the 3rd accumulator piston with a new O-ring.
