Clutch: Adjustments
Clutch Pedal, Clutch Pedal Position Switch, and Clutch Interlock Switch Adjustment
NOTE:
- For a cruise control problem, check the clutch pedal position switch Clutch Pedal Position Switch Test.
- For a clutch interlock operation problem, check the clutch interlock switch Clutch Interlock Switch Test.
- Remove the driver's floor mat before adjusting the clutch pedal.
- If there is no clearance between the master cylinder piston and the push rod, the release bearing will be held against the diaphragm spring, which can result in clutch slippage or other clutch problems.
1. Disconnect the clutch pedal position switch connector and the clutch interlock switch connector.
2. Loosen the clutch pedal position switch locknut (A), and back off the clutch pedal position switch (B) until it no longer touches the clutch pedal (C).
3. Loosen the clutch push rod locknut (D), and turn the push rod (E) in or out to get the specified height (F), and the stroke (G) at the clutch pedal. If adjusting the push rod causes the clutch pedal to contact the clutch pedal position switch, back off the switch further.
4. Tighten the clutch push rod locknut (A).
5. With the clutch pedal released, turn in the clutch pedal position switch (B) until it contacts the clutch pedal.
6. Turn in the clutch pedal position switch an additional 3/4 to 1 turn. Make sure the clutch pedal height did not change.
7. While holding the clutch pedal position switch, tighten the locknut (C).
8. Loosen the clutch interlock switch locknut (A).
9. Fully press the clutch pedal to the floor, then release the clutch pedal 9-12 mm (0.35-0.47 in) and hold it there.
10. Adjust the position of the clutch interlock switch (B) so the engine starts with the clutch pedal in this position.
11. While holding the clutch interlock switch, tighten the locknut.
