Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are
worn or damaged, use new Caterpillar parts for replacement.
Note: Apply a light film of 10W oil to all components before assembly.
1. Check all of the O-ring seals and the components for wear or damage. Replace the
components, if necessary.
