Clutch Pedal
Adiustment
NOTE:
. To check the clutch interlock switch and clutch
switch, see section 23.
. The clutch is self-adjusting to compensate for wear.
CAUTION: lf there is no clearance bstwa€n the mas-
ter cylinder piston and push rod, ths roloase bearingis held againsi the diaphragm spring, which canresuh in clutch slippage or other clutch probloms.
1. Loosen locknut A, and back off the clutch switch (or
sdjusting bolt) until it no longer touches the clutchpeoar.
2. Loosen locknut C, and turn the push rod in or out toget the specified stroke (@) and height (@) at theclutch oedal.
3. Tighten locknut C.
4. Thread in the clutch swirch (or adjusting bolt) untilit contacts the clutch oedal.

Turn the clutch switch {or adjusting bolt} in an addi-
tional 3/4 to 1 full turn.
Tighten locknut A.
Loosen locknut B on the clutch interlock switch.
Measure the clearance between the floor board and
clutch pedalwith the clutch pedal fully depressed.
Release the clutch pedal 15 - 20 mm (0.59 - 0.79 in)
from the fully depressed position and hold it there,Adjust the position of the clutch interlock switch sothat the engine will start with the clutch pedal in
this position.

CAUTION:
. Do not spill brake fluid on the vehicle; it may damage
the paint; if brake tluid does contact the paint. wash
it off immediately with water.
. Plug the end ol the clutch line and leservoir hose
with a shop towel to prevent brake tluid trom coming
