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.

DISMOUNTIN G
In the engine compartment:
Cut the rubber bellows maintaining clip and push it towards cowl panel.
By means of the PF 476 device, depress the ball joints of the steering rods funnel from the
steering knuckle.
Dismo unt :
- connection screw between the cardan joint of the steering column lower shaft and the
steering rack gear shaft;
- steering box attachment screws on the crossbeam.
Detach the steering box assembled with the steering rods.
R EMOU NT I NG
Perform the dismounting operations in the reverse order, observing the required tightening
moments. In case a new steering box is mounted, the parallelism is obligatory to be adjusted, observing
the parallelism adjusting procedure described in chapter 31.

Steering box pusher
ADJUSTMENT
When a noise is found in the area of the
st eering box pusher, it is obligatory to per-
form its correct adjustment.
1. Noise identification (clattering).
Hold by ha nd the rack in pusher’s side and
check the tra nsversal c leara nce (up-down). A
noise in the pusher’s area might occur while driv-
ing, caused by a clearance followed by a noi se
(clattering). If the clearance at the pusher is bigger than
0.31 mm, adjust the cleara nce and/or dismount
the steering box and eliminate the cause.
2. Checking and adjustment of the
push er’s clearance.
The pusher adjustmen t is to be performed tak-
ing into consideration both the rack wear and the
pusher’s wear:
- bring t he ra ck i n the minimum radial
runout position; - position the fe eler of a comparative
gauge on the cylindrical part of the rack ( oppo-
site to the threaded part) in the area of rack exit
from casing ( gear side); - rotate the gear on the whole rack length
and establish the minimal runout point, where the
value read on the gauge is minimal; - adjust the comparing gauge to zero;
- by means of a 17 mm fi xed wrench,
rotate the rack from the opposite end unt il the
pusher is in contact with the thre aded plug( a
higher wrench effort may be noticed for a re-
duced movement red on the comparing gauge);
- read the value shown by the comparing
gauge which must be smaller than 0.31 mm.
The pusher clearance adjustment is performed in
the minimal runout point by rotating the threaded
plug ( 4) to a moment of 1± 0.2 daNm and un-screwing ˘ rotations, then secure it by bead-
ing (caulking) in “S” area.
When mounting, put 23 ± 5 cm
3 grease
UM 185 Li2M for : rack, gear, sealing ring
and pusher’s spring, inner surface of t he
threaded plug. Check the operation and check also during
driving if the steering wheel is returning at the
straight line driving position (steering central
point).

DISMOUNTIN G
Loosen the screws of the right front wheel.
Lift the vehicle by means of a two-column elevator.
Dismount the right front wheel.
Dismou nt :
-steering box casing protection bellows-left steering rod end;
-the right steering connected rod.
Rotate the steering wheel t o the right (complete turn), the rack is withdrawing towards left.
Remove, by means of a screwdriver the used noise absorber bearing.
R EMOU NT I NG
Carefully clean t he rack and the noise absorber bearing seat and grease with special grease
containing MoS2 and then mount the new noise absorber bearing.
Position the pins (A) in their casing seats.
Rotate the steering wheel to the left until t he rack stands out the bearing.
Remount on the rack: - the steering c onnecting rod (safety washer and limiter washer a re t o be obligatory
positioned on the threaded side of the joint body); -protection bellows.
Check and adjust the parallelism, if necessary.

Bellows
REMARK :
A damaged bellows is t o be obligatory replaced with a new one.
BELLOWS MOUNTING
Bellows mounting is performed by means of a con-shaped device that i s positioned on the
connecting rod joint body (axial ball joint) for bellows easy sliding and avoid damaging.
Put some UM 185 Li2M grease on the bellows part in contact with the joint body (axial ball
joint), to easy the bellows sliding.
Mount a new collar for bellows maintaining on the steering box casing.
REMARK :
It is OBLIGATORY to bring the steering in t he straight line driving position of t he
front axle wheels (steering central point) in order to ensure the air balance inside the
s teering box.

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).
