Overview of the entire car-5
The friction, disc, single-diaphragm spring clutch, hydraulic control mechanism. The external diameter of friction disc D=225mm,
internal diameter d=150mm, material is F810.
Adjustment of clutch pedal:
1. Measure the height of clutch pedal (from pedal pad surface to floor) and free stroke of clutch pedal (fork bar pin clearance).
Standard height of clutch pedal: flush with the brake pedal, free stroke of clutch pedal is 5-15mm;
2. Readjust the free stroke of pedal after adjust the height of pedal; rotate the push bar to the standard value, then fix the bolt
and nut;
3. If the free stroke of clutch pedal is not within standard value, it should rotate the adjusting bolt to standard value, then fix
the bolt and nut. Do not move the push bar to main cylinder when adjust the free stroke of pedal;
4. If the free stroke of clutch pedal and clearance between the clutch pedal and floor when the clutch is disengaged de not
consist with the standard, this may by caused by the air in hydraulic system and failure of main cylinder or clutch. It can
discharge the air of system or dissemble and inspect the main cylinder or clutch.
