3.2.3.2 Adjustment of clutch coupling pedal free travel

ATTENTION: TOO SUBSTANTIAL PEDAL TRAVEL WILL NOT ALLOW TO DISEN-
GAGE THE CLUTCH FULLY AND WILL HAMPER GEAR SHIFTING. ABSENCE OF FREE
PEDAL TRAVEL WILL LEAD TO COUPLING DISCS SLIPPING, AND RAPID WEAR OF THE
DISCS AND OVERHEATING OF CLUTCH PARTS!
Clutch pedal free travel, measured with non-running engine, shall be within the limits
from 40 to 50 mm. If this value is too high or too low, adjust clutch pedal free travel.
To adjust free travel proceed as follows:
- loosen lock nut 4 (figure 3.2.4) of fork 3, unlock and remove pin 2, disconnecting
arm 5 from lever 1;
- unscrew adjusting bolt 8 until pedal 6 touches floor of the cabin;
- turn lever 1 anticlockwise against the stop, that is until the release bearing touches
CC release levers;
- adjust length of arm 5, rotating fork 3 until holes in the fork align with the holes in
lever 1. Then screw in fork 3 five turns (shorten the arm).
- tighten lock nut 4, connect fork 3 to lever 1 with the help of pin 2.
If your tractor is equipped with the creeper, then to avoid hanging of pedal 6 it is
necessary to install up to four washers 11. Decrease of clutch pedal free travel up to 35 mm is
allowed.
ATTENTION: MAKE SURE THAT THE CLUTCH PEDAL SAFELY RETURNS ALL THE
WAY UNTIL IT STOPS AGAINST THE FLOOR IN THE AREA OF PEDAL FREE TRAVEL.
OTHERWISE, ADJUST FORCE OF THE SPRING OF SERVO 7 (FIGURE 3.2.4) WITH THE
HELP OF BOLT 8 OR CHANGE THE POSITION OF BRACKET 9, TURNING IT ANTI-
CLOCKWISE RELATIVE TO THE AXIS OF THE MOUNTING BOLT!
