17. To disassemble these valves, insert soda straws (3) in each end of the threaded holes, refer to Figure 3. Remove the steering control valve housing from the vise and tilt it until the port face (4) is upward. Continue turning until the roll pins (2) and ball checks (1) slide through the straws (3).

Inspection
1. Clean all parts in cleaning solvent and air dry on paper towels. Do not use cloths to wipe parts dry, as it may leave lint on the parts.
2. Check all machined surfaces for wear or damage. If there are rough places on the ends of the gerotor star or gerotor (4), steering control valve housing (7), end cap (2), or spacer plate (5), use 600 grit emery cloth to smooth the surfaces, refer to Figure 2. Place the emery cloth on a flat surface. If the emery cloth is new, rub a piece of steel across the emery cloth six times to remove the sharp pieces of grit. Make sure that the part is held flat on the emery cloth. Rub each part across the cloth six times. Check to see if the rough places are removed. Use this method until all rough places are removed. Clean the parts in cleaning solvent to remove any grit.
3. If the spool (9) and sleeve (8) or the bore in the housing of the steering control valve (7) is damaged or worn, use a new steering control valve.
4. Inspect the cap screws (1), pin (11), backup washer (15), seal ring (16), O-ring (17), needle thrust bearing (13) and bearing race (14). Use new parts as required.
5. If your steering control valve has anti-cavitation and check valves, inspect the balls checks (20), (23) and roll pins(21), (22) for damage or wear. Use new parts as required.
