T.FITTING
Apply vacuum slowly and continuously while watch-
ing the gauge.
The vacuum should stabilize momentarily at 0.8 -
2.1 kPa {6 - 16 mmHg, 0.2 - 0.6 in.Hg).
lf the vacuum stabilizes (valve opens) below
0.8 kPa (6 mmHg, 0.2 in.Hg) or above 2.1 kPa
(16 mmHg, 0.6 in.Hg), install a nsw valve and retest.
Move the vacuum pump hose from the vacuum fit-
ting to the pressure fitting, and move the vacuum
gauge hose from the vacuum side to the pressure
side as shown.

The pressure should be stabilize momentarily
above 1.0 kPa (8 mmHg, 0.3 in.Hg).
. lf the pressure momentarily stabilizes (valve
opens) above 1.0 kPa (8 mmHg, 0.3 in.Hg), the
valve is OK.

Adjustment
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 between the mas-
ter cylinder pislon and push rod, the release bearing
is held against the diaphragm spring, which can
result in clutch slippage 01 other clutch problems.
1. Loosen locknut A, and back off the clutch switch (or
adjusting bolt) until it no longer touches the clutch
peoar.
2. Loosen locknut C, and turn the push rod in or out to
get the specified stroke {@} and height (@) at tne
clutch pedal.
3. Tighten locknut C.
4. Thread in the clutch switch {or adiusting bolt) until
it contacts the clutch pedal.

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 pedal with 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 so
that the engine will start with the clutch pedal in
this position.
Thread the clutch interlock switch an additional in
3/4 to 1 full turn.
