Pressure Testing — '96 Model

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.

guide and 1st gear collar with a feeler gauge.

STANDARD: 0 - 0.08 mm (0 - 0.003 in)

NOTE: Take measurements in at least three places,

and use the average as the actual clearance.
