- if the value of piston projection is different, do the following:
- unlock the spherical nut 40;
- screwing the spherical nut 40 in or out, attain the dimension “M” for piston 37 pro-
jection when depressing the pedal 10;
- tighten the nut 39;
5. Bleeding of the hydraulic system of clutch operating control in accordance with
clause 3.3.4.2 of this manual.
6. Adjusting of response of sensors of clutch disengaged state on forward motion and
on reverse, as specified in subsection 3.5 “Electrical part of gearbox control”.
3.3.4.2 Bleeding of the hydraulic system of clutch operating control
Before bleeding fill a tank 1 (figure 3.3.4) of the main cylinder 12 and a balance
chamber of the main cylinder 19 with braking fluid. Then bleed the hydraulic system of
clutch operating control on forward motion and on reverse:
1. Bleeding of the hydraulic system on forward motion:
- fill the tank 1 with braking fluid up to “MAX” mark;
- remove a protective cap 29 off the operating cylinder 32 and put a rubber hose on
the head of the relief valve 30, immersing it a container with braking fluid;
- depress the clutch pedal for several times;
- holding it depressed, unscrew the relief valve 30 by a quarter of a turn, relieving
the braking fluid surplus with air bubbles to the container with the braking fluid;
- screw the relief valve 30 in and release the clutch pedal;
- bleed the system until air bubbles fully disappear in the braking fluid relieved;
- remove the hose and put on the protective cap 29;
- check the braking fluid level in the tank 1 and add, if necessary.
ATTENTION: BLEEDING THE HYDRAULIC SYSTEM OF CLUTCH OPERATING
CONTROL ON FORWARD MOTION, WATCH THE BRAKING FLUID LEVEL IN THE
TANK 1 TO STAY BETWEEN “MIN” AND “MAX” MARKS!
2. Bleeding of the hydraulic system in reverse mode:
- remove the casing 23 of the main cylinder 19;
- check the braking fluid level in the balance chamber of the main cylinder 19, that must not go
below the dimension “
И
” from the top edge of the balance chamber;
- the order of the hydraulic system bleeding is identical to the one on forward motion.
ATTENTION: BLEEDING THE HYDRAULIC SYSTEM OF CLUTCH OPERATING
CONTROL ON REVERSE, WATCH THE BRAKING FLUID LEVEL IN THE BALANCE
CHAMBER OF THE MAIN CYLINDER 19 NOT TO GO BELOW THE DIMENSION “
И
”
FROM THE TOP EDGE OF THE BALANCE CHAMBER!
3.3.4.3 Clutch check for purity of disengagement
After the above stated adjustments on clutch operating control have been carried
out, it is required to check the clutch for purity of disengagement, for this purpose do the
following:
- engage the parking brake;
- start the engine and set the engine speed to (1400±100) rpm;
- fully depress the clutch pedal and not earlier than after five seconds engage the GB
ranges, which shall be “pure”, i.e. without additional sounds and rasp.
In case there are additional sounds and rasp, it is needed to carry out a check and,
if necessary, make repeated adjustments, listed in clause 3.3.4.1.
With the clutch pedal fully depressed the piston 37 projection (figure 3.3.4) of the
hydraulic booster 35 shall make not less than 23 mm.
