REMOU NT I NG
At each dismounting, it is OBLIGATORY the replacement of the limiter washer( 1) as well
as of the safety washer ( 2).
M ount in the rack : j oint body ( 3), not before positioning the safety washer ( 2), the limiter
w asher (1) and oiling the t hreaded pa rt ( 4) of the j oint body with FIXAMED R 58-C.S.1/82
(not excessively).
After tightening to t he required m oment of the axial ball joint on the rack, bend the safety
w asher over one of the cuts made on the joint body.
By means of the DIR 1306 , lock up the rack in regard to t he steering box casing.
Tighten to the required moment of 5 daNm, the joint body in the rack by means of the
DIR 505 wrench.
M ount the funnel ball joint in the steering knuckle arm, then tighten the nut to the required
moment of 4 daNm.
P osition the steering at the middle point ( wheels being in straight line position) in order to
balance the air from bellows. Mount the bellows in its c hannel from the steering box casing and secure it using a clip.
CHECKING
S lightly tighten by hand one of the bellows in order to check the other one inflation, in this
way, the good air circulation inside the steering box is checked. Check the steering geometry and adjust the parallelism if necessary.

General
CONSTANT POWER STEERING (CPS)
1. Power steering pump
2. Power steering box
3. High pressure piping
4. Low pressure piping
5. Oil reservoir
6. Rotary valve
7. Pressure controller
8. Accessories belt
9. Rigid ducts
10. Steering box working
chambers
The working principle of the Constant Power Steering (CPS ) system, consists in steering
hydraulic assistance by hydraulic fluid (oil) passing through a drawer (the two chambers ( 10)
from steering box) with double effect and through a rotary valve ( 6) that is distributing the fluid
through two pipes (9) towards the steering box ( 2) subject t o the full turni ng direction of the
directing wheels. The hydraulic assistance is ensured by a pressure controller ( 7) attached on the high pressure
pipe (3) and connected to the injection computer.
The injection computer is receiving information, during power steering operation, about the
pressure value in “high pressure circuit” ( which may be seen by means of the CLIP tester). The
pressure value in “high pressure circuit” is depending of the pomp conducted pressure as well as
of the used oil fluidity. The more pressure is high, the power steering pump is absorbing more additional energy.
The power steering pump ( 1) is continuously providing in the circuit a constant hydraulic fluid
(oil) flow, regardless the engine RPM, based on the fact t hat pump is driven by the accessories
belt (8). In this case, the system has the generic denomination of “ Open Center System “
REMARK:
The steering is not to be ful ly locked at maximum m ore than 45 seconds at an engine
RPM of 2500 rot/min (risk of power steering pump damaging).

Before remounting, check: and if necessary,
perform the following adjustmen ts:
Detach the connection screws of the rigid
brake ducts from the main brake pump.
Disconnect the electrical contact from ICP
transducer. Dism ount t he m ain pum p fr om t he
ser vobrake.
Disconnec t the suction hose off t he
ser vobrake.

Dismou nt :
- the connecting shaft ( 1) between the
coupling fork and the pedal ; -the attachment nuts of the servobrake
on cowl panel. Dismount the servobrake .
1.The adjustment of the exit rod (P1) ( brake
pump side) which is obtained by acting on the
nut which is one with the pushing rod, in order to
obtain value X = 9
-0.2 mm.
This value is measured between the pushing rod
end and the rest surface of the main cylinder on
ser vobrake.
2.The adjustment of the pushing rod (P2)
( brake pedal side) in order t o obtain the value
L = 107.7
-0.5
mm , which is obtained as follows:
- unscrew the lock nut E and by;
- act on t he c oupl i ng fork ( C) unt i l
obtaining the value L = 107.7
-0.5 mm;
- lock the lock nut ( E).
The L va lue, is to be measured between the
ax le of t he coup l i ng fork whol e a nd t he
ser vobrake rest surface on cowl panel.
For remounting, perform the dismounting
operations in the reverse order. Dismount the ICP transducer from the brake
pump. Purge the brake circuit.

ATTENTION !
The tightness of the servobrake is checked on t he vehicle, with t he hydraulic cir-
cuit under operation Connect the vacuum meter between the servobrake and the inlet manifold by means of a “
T ” type connector. The connecting hose of the vacuum meter shall be as long as possible.
Start the engine and let it idle run for 1min.
Block the air suction hose by means of the MOT 453 device.
Stop the engine.
If air suction lowers with more than 33 mbar (25 mm Hg) in a 15 seconds period, it means
there is a loss at t he retainer valve (replace the valve) or at the servobrake membrane (replace
the servobrake). Dismount the MOT 453 device.
Dismount the vacuum hose.
Reinstate the connection between the servobrake and the inlet manifold by means of
the vacuum hose. TIGHTNESS CHECKING
