The pedal height measurement is gauged from the angled section of the floorboard to the center of the clutch pedal pad. If necessary, adjust the pedal height by loosening the locknut and turning the pedal stop bolt, which is located above the pedal toward the driver's seat. Tighten the locknut after the adjustment.
The pedal height from the floor panel is as follows:
4Runner: 6.8897.283 in. (175.0185.0mm)
Check the pedal free-play to see if it is correct: push in on pedal until the beginning of the clutch resistance is felt. If there is a lot of free-play, make adjustment.
To adjust, loosen the locknut and turn the pushrod until the free-play is correct. Tighten the locknut. After adjusting the free-play, check the pedal height.
Pedal free play should be as follows:
4Runner: 0.1970.591 in. (5.015.0mm)
PEDAL PUSHROD PLAY
The pedal pushrod play is the distance between the clutch master cylinder piston and the pedal pushrod, located above the pedal towards the firewall. Since it is nearly impossible to measure this distance at the source, it must be measured at the pedal pad.
If necessary, adjust the pedal play by loosening the pedal pushrod locknut and turning the pushrod.
Pedal push rod free play should be as follows:
4Runner: 0.00390.197 in. (1.05.0mm)
