Re mounting is done by performing in the reverse order, the dismounting operations.
Before mounting grease the parts with  grease UM 170LiCa Pb

Tighten at the required moment the attachment  nuts and screws:

- nuts M8       ..........................1,5 - 2 daNm
- screws M7    .......................... 1 - 1,5 daNm

GEARS CONTROL ADJUSTMENT

Engage the end lever of the gearbox in the

velocity step IV.

Place in contact  the plug of the control

lever with an adjustment washer of 13 +/- 0,5 mm,
placed between the control box wall  and the
plug, observing also the value W = 56 +/-1.

Tighten at the required moment the strap

attachment screws  (1,8 –1,9 daNm) and the
elastic joints  at the control shaft end
(1,1 – 1,9 daNm) observing the value L=10.

The strap must be in horizontal position

with the screws heads down.

Attach the return spring.

NOTE:

Before mounting grease the joints with

 grease LiMoS2

ELECTROVACUUMATIC CONTROL SYSTEM

4X4 COUPLING

It is used for the Dacia 1304, 1307 vehicles equipped with 51 C type gearbox, for

front transmission coupling. This is allowed after vehicle stopping or during driving, at a
speed of max.10 km/h, after declutching.

The specific elements of this system may be identified in the above drawing:

- the vacuum capsule (12) – attached on the gearbox left half casing (11); it has the

purpose of mechanic control of the front transmission coupling and uncoupling.

- electric valves ( 3 and 4 ) are placed in the engine compartment, on the right wing

lining. These are destined to open or close the vacuum route between the inlet manifold
and the two vacuum capsule compartments ;

- 4x4 switch – is placed on dashboard. When this is operated, the front transmission

coupling is controlled.

- intermediary relay- is placed under the dashboard, on the left side and it is controlling

the lighting of the “ 4 x 4 “ warning light on the instruments panel, when front transmission
coupling is done.

- vacuum tank (5) – is placed in the engine compartment, being attached by means

of a clamp, on the right shock absorber column.

- vacuum control ducts assembly – is performing the vacuum route, between the

inlet manifold , the vacuum tank, electric valves and the vacuum capsule.

- one-way vacuum valve ( 2 ) – is placed on the connection hose between the inlet

manifold and the electric valves.

- “ 4x4 ” coupling control wiring – is performing the connection of the system

components to the vehicle electrical equipment.

The system is working based on the vacuum from the inlet manifold (1), which, during

engine running, is acting on the membrane separating the two vacuum capsule compartments
(12). This will impose the longitudinal movement of the capsule axle, which by means of
the control lever (6) will act upon the front transmission coupling  control axle (7), placed
in the gearbox right front part (1) . In this way is performed the front transmission coupling
and the transit from rear drive to all  wheel drive (4 x 4).
