HAND BRAKE-ADJUSTMENT
The adjustment of the ha ndbrake shall be perform with the vehicle lift on a two columns
elevator.
NOTE
The adj ustment i s obligatory performed anytime t he shoes and secondary c ables
have been replaced.
Release the control lever of the hand brake (release position).
U nscrew the lock nut (2).
Tighten the nut ( 1) until the shoes gaskets come lightly into contact with the brake drum.
The adjustment shall be pe rformed so that is insuring a hand brake l ever stroke of min.12
teeth until the blocking of the wheels.
Tighten the lock nut ( 2) at the required moment of 2 daNm.
Lower the vehicle from the elevator.

BRAKE PRESSURE CONTROLLER
Brake pressure controller, load sensitive, avoiding the rear wheels blocking.
OPERATION PRINCIPLE
The brake pressure controller enables the rear circuit pressure “ modulation “ according to
two parameters:
-the pressure value in the front circuit
- the load on the rear axle
The pressure controller is operating on the principle of pressure compensation in two enclosures,
separated by means of a ball and spring valve. The back pressure at the valve level is created by means of the forc e developed by the
continuos action compensating spring and of the control spring acting in proportion as the rear
axle load is increasing. The pushing rod is transmitting the force of the lever spring to the pressure controller piston,
which is controlling the valve ball being in the open normal position (position P 1).
BRAKING MOMENT
In the same time with pressure increase when entering in the pressure controller, this will act
upon the ball, forcing it to overcome the c ontinuos acting spring force and by uncovering the
valve hole, to facilitate the releasing of this pressure. In the braking moment, due to position
changing of the vehicle body compared to the rear axle, by means of the acting levers, the limiting
piston is moving toward the interior, reducing the fluid exist diameter, leading to the obtaining in
this way of the pressure reduction in the rear circuit.
DE BRAKING MOMENT
In the moment of fluid inlet pressure restoring ( by leg lifting from the brake pedal ), the piston
will come back in the initial position, gradually and quickly allowing the same diameter existent at
the beginning of the braking for which the valve is open ( position P1 ). 1.

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 a ssembly, t he c ontrol ba r or the assembly lever-
control case;
- establishin g of failures such as: gear change impossibility or unexpected gear uncoupling,
gear 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 c ase;
A ttach the control bar to the control 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. THE GEARS CONTROL

DISMOUNTING
For the dismounting
of the front door assembled plate with electric control, dismount:
- the window lifting crank, inner opening mechanism, by detaching from it, the control rod
(8) of the front door opening, the rod which is fixed with the other end on the plate;
- the locking button (2) and the guiding case (3);
- the attachment screw (9 ) of the locking handle;
- the door pa nel.
Disconnect the actuator connector.

Di smount the attachment screws (5) of the box (6) from the caisson of the door.
Remove the electric control assembled plate assembly through the technological opening from
the caisson of the door.
Dismount the attachment screws of the outside opening mechanism on the external panel of
the door.
REMOUNTING
Perform in reverse order the dismounting operations, taking into account the following recom-
mendation:
- for the lock c ontrol mounting, t he lock rod (4) will be pl aced i n the position where t he
lock is blocked; - for the front door plate mounting, the connecting fork (1) of the outside opening mechanism
will be fixed on the existing ball joint on the lock;
mount the button (2) by self-threading on the rod (4).
