3. Slowly depress the accelerator pedal to increase
engine rpm until pressure is indicated on the pres-
sure gauge. Then release the accelerator pedal,
allowing the engine return to an idle, and measure
the pressure reading.
4. With the engine idling, depress the accelerator
pedal approximately 1/2 of its possible travel, and
increase the engine rpm until pressure is indicated
on the gauge. Then measure the highest pressure
reading obtained.
5. Repeat steps 3 and 4 for each clutch pressure being
inspected.
