3. Tighten the clutch pipe flare nut securely with the
SST
Tightening torque:
13—22 N-m (1.3—2.2 m-kg, 9—16 ft-lb)

AIR BLEEDING
The clutch hydraulic system must be bled to remove
air that entered when the pipes were disconnected.
This bleeding is done as described below.
Note
a) The fluid in the reserve tank must be main-
tained at the 3/4 level or higher during air
bleeding.
b) Use only the specified fluid type. (Refer to
page 6—3)
c) Be careful not to spill clutch fluid onto a
painted surface.
1. Remove the bleeder cap, and attach a vinyl hose
to the bleeder screw.
2. Place the other end of the vinyl tube in a glass con-
tainer of the appropriate capacity.
3. Slowly pump the clutch pedal several times by
hand.
4. While the clutch pedal is depressed, loosen the
bleeder screw to let fluid and air escape.
Then close the bleeder screw.
5. Repeat step 3 and 4 until no more air bubbles are
in the fluid.
6. Check for correct clutch operation.
