Inspection

1. Clean control valve body, valves, springs and other parts in solvent and air dry.

2. Inspect valves for cracks, scoring and free movement in bores.

3. Inspect bushings for cracks or scored bores.

4. Inspect valve body for cracks, damage or scored bores.

5. Inspect springs for distortion or collapsed coils.

6. Inspect bore plugs for damage. Install all flared coiled pins (zinc coated), with flared end out and from the machined face of the control valve assembly. Install the two tapered coiled pins (black finish) which retain the throttle valve and bushing, with tapered end first. Coiled pins do not fit flush on rough casting face. Make sure all coiled pins are flush at machined surface
