M aintaining the transmission on the press, on both sides, shall be ensured on the G
groove made on shaft, by means of a device type FACOM U 53 G, ( the flat side towards
bellows) in order t o avoid the defl ector damages on the wheel side. The pressing effort of the beari ng on the tra nsmission shaft ahas the value of = 100 –
700 daN. Press again the assembled tripod on the tra nsmission shaft observing the marks made
when depressing. The pre ss effort of t he tripod assembly on t he groove d area of t he shaft end, shall be
between 60 – 600 daN. Remount the blocking ring (Zeger lock) in the groove made on the tra nsmission shaft.

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.

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.

OPERATIONA. B RAKING
THE FRONT BRAKE CIRCUIT
The primary piston is controlled by the pushing rod. A part of the brake fluid under pressur e
will operate together with the spring on the secondary piston, and the other part of the brake flui d
shall penetrate through the ducts to the upper floor towards both exits leading to the front brak e
calipers.
THE REAR BRAKE CIRCUIT
The secondary piston is continuing its movement, conducting the brake fluid under pressure ,
through the ducts, to the upper floor, towards the exit to the pressure-reducing valve. During al l
this time, the linings-pistons assembly will be balanced due to the two side springs .
