25–04 Hydraulic Fluid
Replacing
Replace the clutch hydraulic fluid every two years to
ensure clutch function is reliable and correct. Use the
procedures below. Fluid replacement must be done
at an authorized Freightliner service facility.
Draining and Filling
1. Shut down the engine.
2. Apply the parking brakes, chock the front and
rear tires, and open the hood.
WARNING
Clutch hydraulic fluid (DOT 3 brake fluid) is haz-
ardous. It may be a skin irritant and can cause
blindness if it gets in your eyes. Always wear
safety glasses when handling clutch hydraulic
fluid or bleeding hydraulic lines. If you get clutch
hydraulic fluid on your skin, wash it off as soon
as possible.
3. Using a flat-head screwdriver, remove the quick-
disconnect clamp that attaches the hydraulic
hose to the slave cylinder. Retain the clamp for
later installation. See Fig. 3.
