5. Remove the old filter (Figure 56) and wipe the
surface of the filter adapter gasket clean.
6. Apply a thin coat hydraulic fluid to the rubber
gasket on the replacement filter.
7. Install the replacement hydraulic filter onto the
filter adapter (Figure 56). Tighten it clockwise
until the rubber gasket contacts the filter
adapter, then tighten the filter an additional
3/4 turn.
8. Clean up any spilled fluid.
9. Start the engine and let it run for about two
minutes to purge air from the system.
10. Stop the engine and check for leaks.
Hydraulic fluid escaping under pressure
can penetrate skin and cause injury.
Fluid injected into the skin must be
surgically removed within a few hours by
a doctor familiar with this form of injury
or gangrene may result.
• Keep your body and hands away from
pin hole leaks or nozzles that eject
high pressure hydraulic fluid.
• Use cardboard or paper to find
hydraulic leaks, never use your hands.
