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.

5. Slowly pressurize the vapor lin€ while watching the
gauge.
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.

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.

a Attach a hose to the bleeder screw, and suspend
the hose in a container of brake fluid.
. Make sure there is an adequate supply of fluid at
the clutch master cylinder, then slowly pump the
clutch pedal until no more bubbles appear at the
bleeder hose.
. Refill the clutch master cylinder with fluid when
done.
. Always use Genuine Honda DOT 3 Brake Fluid.
Using a non-Honda brake fluid can cause corro-
sion and decrease the life of the system.
. Confirm clutch operation, and check for leaking
flu id.
