WHEELS AND TYRES
CARACTERISTICSRIMS
The wheels identification marking is represented in two ways:
- engraved marking for steel rims
- cast marking for aluminum rims
The marking enables acknowledgment of the main wheels dimensions criteria. This marking
may be:
complete,
Example: 5
1/2 B 13 4 CH 46 ; 5 1/2 J 13 4 H2 46
or simplified,
Example: 5
1/2 B 13 ; 5 1/2 J 13 H2
The wheel bolts (studs) are situated on a diameter of 100 mm.
Maximum axial runout : 1 mm measured on the rim edge ( in G ).
Maximum radial runout : 1 mm measured on the supporting side of the tires beads.

The wheels screws tightening moment : 7,5 daNm.
The inflating pressure must be checked at cold.
The temperature raising during driving, leads to a pressure increase from 0.2.
to 0.3 bars. In case temperature checking is done at warm, take i nto account this pressure increase and
never deflate it. A

DISMOUNTING
Loosen the screws of the wheel;
Lift the front part of the vehicle;
Dismount the wheel;
Di smount t he ba ll joints of the steering
auxiliary connecting rods. Di
smount the attachment scre w of the
steering wheel shaft (1) from the steering box.
Dismount the steering box attachment screws (2) on the cross member.
Dismount the steering box together with the steering auxiliary connecting rods.
NOTE
Do n ot ever dismount the axial ball joints from the rack, unless they need to be
replaced.
REMOUNTING
Perform the dismounting operations in the reverse order:
Grease the joints with special grease containing MoS2.
Check the condition and the attachment of the protection bellows.
Tighten at the required moment the nuts of the steering auxiliary connecting rod - in the case
of the dismounting of an auxiliary connecting rod. Mount the steering box and the auxiliary connecting rods assembly, on the vehicle.
Check the parallelism.

PUSHER ADJUSTMENT
The pusher adjustment shall be performed taking into consideration, the wear degree of the
rack and the pusher.

2. ”0” ring
3. Pusher spring
4. Assembled threaded plug
When mounting distribute 23 + / - 5cmc
of grease II Li Ca Pb with MoS2 for: the
rack, the gear, the pusher and the spring, the
inner surface.
ADJUSTEMENT METHOD
The clearance adjustment of the pusher is performed by tightening the threaded plug at the
required moment of 1+/-0,2 daNm and unscrewing it ˘ round.
The moment for the gear rotation will be
about 0,15 daN.m (maximum accepted 0,25
daN .m ) on the whole length of the rack or
the rack gliding effort of 25 daN (maximum
accepted 40 daNm ) without rigid points.
Securing of the unscrewing of the threaded
plug is perform ed by the distort ion of t he
securing element of the assembled threaded
plug towards the casing in two antipodal
points.

NOISE ABSORBER BEARING
DISMOUNTING
Loosen the screws of the wheel;
Lift the front part of the vehicle
Dismount the wheel on the opposite side of the steering column;
Dismou nt :
-casing protection bellows;
-the steering auxiliary connected rod.
Rotate the steering wheel until the rack is withdrawn.
Remove, by means of a screwdriver the noise absorber bearing.
REMOUNTING
Carefully clean t he rack and the noise absorber bearing seat and grease with special grease
containing MoS2.
In the same way as at the dismounting, place back the noise absorber bearing paying attention
to fix the three pins (A) in their seats.
Rotate the steering wheel in the opposite direction until the rack stands out the bearing.
Remount on the rack: - the steering auxiliary connecting rod (mount a new safety washer);
- protection bellows.
Check and adjust the parallelism, if necessary.

Before assembling the rack with the steering auxiliary connecting rods (the threaded parts
being free from any tra ces of grease) a pply a layer of FIXAMED R 58- C.S. 1/82 on the
threaded parts of the auxiliary connecting rods. Place the safety washer and t he l ocker washer (in t his order) on the threaded shaft of the
steering auxiliary connecting rod, passing the curved pin of the safety washer through the slot of
the locking washer. Screw the steering auxiliary connecting rod in the rack.
Tighten the joint body at the moment of 5 daNm by means of the 6902-4105 special wrench.
Bend the safety washer in the opposite part to t he pin in at l east one of the cuts made on the
ball joint body. Mount the bellows in its channel from the steering casing.
Mount the auxiliary connecting rod funnel in the steering knuckle support.
Check the tightening of the nut (5) at a moment of 4daNm,on the vehicle.
