CLUTCH SYSTEM
Clutch Pedal
5) Remove the following parts (B to H) from clutch
pedal bracket (A) as shown in the figure.
6) Remove the spacer, bushing and pedal pad from
clutch pedal.
D: ASSEMBLY
1) Attach the stopper, etc. to pedal bracket tempo-
rarily.
2) Clean inside of bores of clutch pedal and brake
pedal, apply grease, and set bushings into bores.
3) Align bores of pedal bracket, clutch pedal and
brake pedal, attach the brake pedal return spring,
assist rods, spring, and bushing.
NOTE:
Clean up inside of bushings and apply grease be-
fore installing the spacer.
4) Install the hill holder cable to clutch pedal.
E: INSPECTION
1. CLUTCH PEDAL
Move the clutch pedal pads in the lateral direction
with a force of approx. 10 N (1 kgf, 2 lb) to ensure
pedal deflection is in specified range.
NOTE:
If excessive deflection is noted, replace the bush-
ings with new ones.
Deflection of clutch pedal:
Service limit
2.0 mm (0.079 in) or less
F: ADJUSTMENT
1. LHD MODEL
1) Measure the full stroke amount of clutch pedal.
NOTE:
 Measure the length between seat cushion front
end and center portion of clutch pedal.
 Slide the seat at seventh notch from first notch.
