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.
