3. Rotate the hydraulic-pressure filter counterclockwise
and remove the filter (Figure 92).
Note: Discard the filter.
4. Apply a thin layer of the specified hydraulic fluid to
the O-ring of the new filter.

filter, causing it to leak.
5. Install the new filter.
Note: Use your hands to tighten the filter an additional
half turn after the filter makes contact with the filter
head.
6. Check the level of the hydraulic fluid in the hydraulic
reservoir; refer to Checking the Hydraulic Fluid Level
(page 24).
7. Start the engine and let it idle for 1 or 2 minutes.
8. Stop the engine.
9. Check for leaks around the filter area.
10. Check the level of the hydraulic fluid in the hydraulic
