3.1.4. Removal and installation of a pedal of coupling
Check of a technical condition
Check an axis and the pedal plug on wear existence.
Check a coupling pedal on bend and distortion existence.
Check a returnable spring on damage or easing existence.
Check a pedal platform on damage or wear existence.
Check pedal height over a floor (from an external surface of a platform of a pedal to a floor) (fig. 3.13)
Nominal size "And": 182,7 mm.
Fig. 3.14. Adjustment scheme педели couplings
If the pedal height over a floor does not correspond to norm, adjust it, as is shown in drawing 3.14
Bolt adjust pedal height then tighten a lock-nut.
After adjustment tighten a bolt so that it concerned a pedal emphasis then tighten a lock-nut.
Rotation of a pusher adjust its length on new height of a pedal then fix a pusher a nut.
At adjustment of height of a pedal watch that the pusher was not displaced towards the main cylinder.
Upon termination of adjustment be convinced that the free wheeling of a pedal of coupling (measured from a surface of a platform of a pedal) is in norm limits.
Nominal rate "In": 6–13 mm.
Fig. 3.15. Free wheeling of a pedal of coupling
If the free wheeling of a pedal of coupling does not correspond to norm, the possible reasons are availability of air in a hydraulic actuator or malfunction of the main cylinder. Pump over a hydraulic actuator and check the main cylinder or coupling (fig. 3.15)
