Disassembly and Assembly
The numbers in parentheses () listed after the names of
parts in this document match the numbers used in the
construction diagrams and parts lists.
General Precautions
• Perform disassembly and assembly work in a clean
place. Provide clean containers to hold parts during
disassembly.
• Clean around the ports before disassembly. Remove
paint around connectors with a wire brush.
• Clean the disassembled parts with wash oil.
• Put alignment marks on all parts to reassemble them in
the same positions.
• After each disassembly, replace all seals and apply a
thin layer of grease to them.
• Check each part for abnormal wear or seizing. Re-
move any burrs with sandpaper.
• Do not move adjusting screws, unless absolutely nec-
essary.
Disassembly
1. Remove the cap screws (8) and remove the solenoid
coil (2).
• Put alignment marks on the solenoids and body,
to ensure the same position during reassembly.
• Take care not to let the push rods fall out.
Cap screw: 4.9 N·m (3.6 ft.-lb)
2. Remove the O-ring (4) from the solenoid coil (2).
3. Take out the plug (1) and remove the O-ring (3) from
the plug (1).
Plug: 23.5 N·m (17.3 ft.-lb)
4. Remove the spring (5) and the spool (6) from the
body (7).
• Record the spool and body hole positions to use
the same positions during re-assembly.
