age the rubber parts of the system, causing loss
of clutch function and the risk of serious personal
injury.
Hydraulic clutch control fluid is hazardous. It may
be a skin irritant and can cause blindness if it gets
in your eyes. Always wear safety glasses when
handling it or bleeding hydraulic lines. If you get it
on your skin, wash it off as soon as possible.
NOTICE
Do not spill hydraulic clutch control fluid on the
cab paint. Clean it off immediately if any is spilled.
Brake fluid can damage paint.
Do not allow the fluid level in the reservoir to go
below the MIN line. If air enters the system, the
hydraulic system will not operate correctly, and
the clutch could be damaged.
If the fluid level is below the MIN line, fill the reser-
voir with new DOT 4 brake fluid from a tightly sealed
container until the level reaches the MAX line. See
Fig. 3 .
25–03 Fluid Change, Hydraulic
Clutch Control
Replace the hydraulic clutch control fluid to ensure
clutch function is reliable and correct. It can be
changed by pressure bleeding or manual bleeding.
Pressure bleeding can be done by one person and
manual bleeding requires two.

NOTICE
Do not spill hydraulic clutch control fluid on the
cab paint. Clean it off immediately if any is spilled.
Brake fluid can damage paint.
IMPORTANT: The pressure line must slope con-
tinuously downward between the master and
slave cylinders. On some vehicles, the securing
clamps may need to be removed to achieve this
and allow the air to be purged.

NOTE: A bleeder system (J-29532) and a bleed
adaptor (J-35798) for the fluid reservoir are
available through SPX Kent-Moore Tools and
may be used to complete the following proce-
dure. To order these parts, call Kent-Moore at
