EMARK :
It is forbidden to dismount from the power
st eering box the pipes between the rotary
valve and the steering box.
Whe n dismounti ng, the high and low
p ressure pipes are to be positioned with the
connection screws downward oriented, i n
order to avoid contaminants penetration.

Mount :
-steering box
-s teering rods ball j oints in t he steeri ng
knuckle arms; - exhaust
-anti-rocking steering rod;
- cardan joint in the position marke d at
dismounting;
-high and low pressure pipes (remove
MOT 453 pliers), ob serving t he re qui re d
tightening moments; -piping attachment collars;
- wheels;
- battery.
Refill the circuit with oil ( full reservoir).
With stopped engine, easy a ct upon the
steering wheel in both directions, so that rack
is performing a complete double stroke.
Repeat the operation with started engine
(oil pump operatin g), then fill up to the MAXI
mark, the oil level in the reservoir.
Check and eventually adjust the
parallelism.

Power steering box pusher
When an excessive rack clearance,
followed by clattering in the steering box is
occurring, before replacing the steering box,
the pusher with rack is to be adjusted. 1. Noise (clattering) identification.
Lift the vehicle by means of a two-column
elevator; On the pusher side:
- dismount the bellows attachment clip
on the steering box casing;
- push the bellow towards the steering
rod; - hold by hand the rack rod and check
the transversal clearance (up- down). A clearance followed by a noise (clatt ering)
is leading to a pusher noise, during driving. 2. Adjustment
Straigh ten th e caulking (A) of t he
adjustment nut bead (1).
By means of a 10 mm hexagonal wrench,
tighten the adjustment nut until there is no more
clearance.
AT T E N T I O N !
Do not tighten the nut more than 3
teeth.Check if the rack is freely moving all the
length. Bend the adjustment nut bead in the two
opposite slots of the steering box casing, ensuring
in this way its unscrewing.
Positio n the bellows on the steering box casing
and mount a new attachment clip.
Lower the vehicle from the elevator with
wheels on the ground.
Check, during driving if the steering wheel is
coming back to the steering center point.
