Electric proportional solenoid replacement

Removal

1. Disconnect electrical connection and remove three cap screws (B0050) using a 4 mm internal hex

wrench.

2. Remove the solenoid (B0010) and O-ring (B0035A). Discard the O-ring.
3. Remove valve spool (C0100).

Inspection
Clean and inspect valve spool and all machined surfaces for damage or wear. Replace parts if necessary.

Assembly

1. Lubricate and install valve spool (C0100).
2. Using petroleum jelly, lubricate and install new O-ring (B0035A).
3. Install cap screws (B0050) using a 4 mm internal hex wrench. Torque screws to 6 N•m [4 lbf•ft].
4. Reconnect electrical connections and test the motor for proper operation.
