1. Check to be sure that the brake pedal has been completely
returned by the return spring.
2. Disconnect the switch connector.







RTW 780SH003301
3. Release the lock 2 by turning the switch 1 counter-clock-
wise.
4. After doing so, pull the pedal arm
3 to you a little so that
the pedal arm is not pushed in.
5. Making the pedal arm not movable with one hand, push in
the whole switch with the other hand until the plunger of the
switch is pushed in and the switch itself hits the rubber o
f
the pedal arm.
In the condition, turn the switch clock-wise until "click"
sound is made and lock it.
By doing this, the switch is adjusted at 0.2 to 1.2mm (0.01-
0.06 in) clearance.

Clutch Switch



Removal and Installation
Refer to the Clutch Control removal and installation procedure
in Clutch section.

Adjustment
1. Turn the clutch switch or stopper bolt 1 until the switch bolt
or stopper bolt just touches the clutch pedal arm.
2.
Adjust clutch switch or stopper bolt by backing it out half a
turn, and measure the clearance (L) between the clutch
pedal arm and the clutch switch bolt end or stopper bolt.
3. Lock the lock nut
2.
4. Connect the clutch switch connector.

Test
Terminal Testing
1 Using a multimeter, probe the pins of the switch assembly and compare to the table below.
NOTE
The pins are as follows:
• C44 – pins 1 and 2
• C44 – pins 3 and 4
NOTE
Holding the plunger (5) with tape will help when
performing the test with the plunger in the active
position (plunger pressed).

Plunger Position Connector C44 – 1 and 2 Connector C44 – 3 and 4
Neutral position (plunger extended) Open circuit Continuity
Active position (plunger pressed) Continuity Open circuit

Reinstall
1 If removed, install the plastic clip (2) with the arrow pointing upwards, refer to Figure 8C – 11.
2 With the connectors pointing upwards (12 o’clock position), insert the switch assembly (1) into the plastic clip.
