Clutch Hydraulic Fluid
Visually inspect the clutch fluid from the
reservoir
. There are molded lines with the
letters MIN to indicate minimum fluid level
and MAX to indicate the maximum fluid
level recommended for proper operation.
Be sure to maintain the fluid between the
MIN and MAX levels indicated on the
plastic reservoir
. If the fluid level repeatedly
goes below the MIN line, then it is time to
have your clutch adjusted or the hydraulic
system inspected for service. To replace
the fluid, locate the drain fitting on the air
solenoid mounted to the transmission
housing. Open this fitting and allow fluid to
drain out of the system. Once all the fluid is
drained out, close the fitting and fill the
system through the master cylinder
reservoir in the engine compartment. Once
the system is full, then purge the system of
air by simultaneously pressing on the pedal
and opening the fitting to allow air to
escape. Close the fitting when fluid starts
coming out. Then refill the reservoir.
Repeat this until all air has been purged
from the system. Replace with the
recommended fluid per Lubrication
Specification Chart on page 276.
Clutch Adjustment
Some clutches are self-adjusting, however;
there are manually adjusted clutches that
will require the operator to know when to
adjust the clutch. The clutch will need
adjustment when your clutch pedal stroke
seems to get longer and its effectiveness
at a seamless shift becomes less. Another
sign of the clutch needing adjustment is the
level of the fluid in the reservoir. If the
hydraulic fluid is not leaking, but the fluid
level is getting lower, then the clutch may
need to be adjusted. Please take the
vehicle to an authorized dealership to have
the clutch adjusted. See the clutch
manufacturer's Service Manual for the
proper adjustment procedures.
