2. Connect the analyzer special patterns pickup to the step-
per motor-side connector terminal (red clip on the special
tool), terminal 3 (blue clip), terminal 4 (black clip) and
terminal 6 (yellow clip) respectively.
Alternate method (Test

CLUTCH PEDAL CHECK AND ADJUSTMENT
1. Turn up the carpet, etc. under the clutch pedal.
2.Measure the clutch pedal height as shown in the fig ure.
Clutch pedal height
Standard value (A):
mm
3.If the pedal height is not within the standard valu e, loosen
the lock nut and adjust the pedal height to the sta ndard
value using the adjusting bolt (vehicles without au to-cruise
control), or using the clutch pedal position switch or push
rod (vehicles with auto-cruise control).

adjust with the push rod.
Caution
Do not push in the master cylinder at this
time.
After completing the adjustments, confirm that the clutch
pedal free play (measured at the face of the pedal pad)
and the distance between. the
pedal (the face of
the pedal pad) and the
when the clutch is disen-
gaged are within the standard value ranges...
Clutch pedal free play (including the
pin play)
Standard value (C): 6-13 mm

Distance between the clutch pedal and
when the clutch is disengaged
Standard value (D):
mm (2.76 in.) or more
If the clutch pedal free play and the distance betw een
the clutch pedal and the when the clutch is disen-
gaged do not agree with the standard values, it is probably
the result of either air in the hydraulic system or a faulty
master cylinder or clutch. Bleed the air, or disass emble
and inspect the master cylinder or clutch.
Turn back the carpet, etc.

2.Tooth contact pattern, produced when drive gear
height is too large
Cause
The driven bevel is too close to the drive bevei ge ar.
Remedy
Use thicker bevel gear mount adjusting spacer to se parate
the driven bevel gear more from the drive bevel gear.
3. Tooth contact pattern produced when driven bevel gear height is too small
Cause
The driven bevel, gear is too separated from the dr ive
bevel gear.
