Handbrake - adjustment
The adjustment of the handbrake shall be performed with the vehicle lift on a two-column
elevator. Note :
The adjustment i s obligatory performed anytime t he brake shoes or secondary cables
have been replaced.
Release the control lever of the hand brake (release position)
Tighten the nut ( 1) until the shoes lining come lightly into contact with the brake drum.
The adjustment shall be performed so that is insuring a hand brake lever stroke of min.12
teeth until the blocking of the wheels. Lower the vehicle from the elevator.

ADJUSTMENT OF TH E BRAKE PRESSURE CONTROLLER FOR
THE PARALLEL BRAKING SYSTEM
Imposed conditions : -the vehicle on wheels
- empty trunk
- one person on board
ADJUSTMENT METHOD
Mount the flexible connection of the FR 501 device at the purging screw of one rear wheel
cylinder. Purge the manometer.
Push the brake pedal to enable reading several times the limiting pressure obtained on the
rear wheels cylinders.
Unscrew the adjustment nut ( A) to distance it from the pushing rod end (B ).
A ct upon the rod end ( B):
- by unscrewing it towards the pushing rod ( C ) in order to increase the pressure in the
rear circuit;
-by screwing it towards the pushing rod (C ) in order to decrease the pressure in the rear
circuit.
Tighten to the required moment ( 0.15 damn) the adjustment nut (A) locked with the pushing
rod end ( B) so that between the lever end a nd the lever ( D) a c learance of L = 0.5 mm to be
ensured.

GEARS CONTROL ADJUSTMENT
This is to be performed after mounting the engine-gearbox assembly and the assembly lever-
control case every time when : -dismounting of the engine-gearbox assembly, the control bar or the assembly lever-control
case;
- establishing of failures such as: gear change impossibility or unexpected gear uncoupling,
gears blocking.
For the gear control adjustment the CV 550 device i s to be used.
M ount the CV 550 device on the assembly lever- control case.
A ttach the control bar to the c ontrol lever end.
Place the gear lever in the device seat and fix it in this position by means of the device handle.
Tighten the attachment screw 1 of the bar to the lever at the required moment of 1.2 daNm.
Dismount the CV 550 device from the control box.
Check the gears coupling.

R EMOU NT I NG
Perform the dismounting operations in the
reverse orde r, taking into consideration the
following: -before bearing ( 6) closing, grease the
contact parts with the pedal a nd check if t he
pedal rotation in the be aring is done without
noises or locks;
-adjust the pedal stroke at the
“maximum” position of t he valve, which is
obtained by pushing the pedal until pressing on
the limiting part (4).
- the tightening moment of the pedal
bearing attachment nut is of 0.8 daNm. ACCELERATION CABLE
D etach from clips the cable from the
acceleration pedal ( 3) by harpoon ( 5)
compressing. Release the acceleration cable ( 1) from the
valve lever ( A).
Detach from clips the acceleration cable and
release it.
R EMOU NT I NG
First attach the acceleration cable to the
valve lever ( A), and then attach by clips the
other end on the acceleration pedal arm. Push the acceleration pedal until pressing on
the limiting part ( 4) (2-3 pushing). In this
position, the length adjustment is done.
In case of t he buffe r replacement ( 6), the
clip from the cable is to be placed at a 34 mm
