PUSHER
PUSHER ADJUSTMENT
The pusher adjustment shall be performed taking into consideration, the wear degree of the
rack and the pusher.
1. 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.

BRAKE PUMP
REMOUNTING
Perform the dismounting operations in reverse order.
Check the length of the pushing rod , value X = 9 mm and correct if necessary.
Before remounting, check the servobrake pushing rod stroke ( min.30 mm ).
After assemblin g the brake with the fluid reservoir and filling with brake fluid, no leakage must
occur in the surface of separation between the two elements.
IMPORTANT
The I.C.P. transducer is mounted after t he braking system purging.
ICP sub-assembly is not reparable ( ICP – pressure-decreasing indicator)

WELDING TYPES AND P
ARAMETERS
At the reparation of the welded body elements, thre e welding categories may be used:
prot e c t ion ga s weldi ng (CO2), e l e ctri c spot weldi ng and fi l l ing m a teri als wel ding
(autogenous). At the autogenous welding, it is recommended that flame must be slightly inclined so
that arch can be seen and the flame extremity to be maintained at aprox. 5 m m from the
part to be welded.
1. Spot welding resistive para meters for steel plates with carbon c ontent C < 0,15 %.

OLLISION DIAGNOSIS
CENTRAL PA RT CHECKING
This c hecking is performed in the purpose to establish if one of the distortions is not
affecting this floor part, from where the checking starts. Compare the followings lengths : EI = FJ; EJ = FI.
FRONT LONGITUDINAL GIRDERS CHECKING Compare the followings lengths: CG = DH; CH = DG.
If the lengths ( CH - DG) and the diagonals (CG - DH ) are not identical, check again
the point ( 3).
If points (1) and ( 2) are good, the front axle angles may be checked.

REAR LONGITUDINAL GIRDERS CHECKING
Compare the following lengths: EK = FL; EL = FK.
RE AR ARM CHECKING
Compare the following lengths: FM = EN.
If a difference is noticed when measuring the lengths ( FM – EN ), the rear arms are to
be replaced.
The checking operation of the rear arm s is followed by a checking performed with the
gauge fixed on the arm and on the central longitudinal girde r.

DISMOUNTING
Loosen the screw for rod length adjustment (5) of the hatchback opening and detach the rod;
Remove the fork (2) and the gasket (4) releasing the hatchback opening control assembly (3)
Dismount the screws (1) and the special axle (6), releasing the guiding case (7 ) .
REMOUNTING
Perform in the reverse order the dismounting operations, the opening rod length adjustment
being performed with the hatchback opened and the lock blocked, in order that aft er three
consecutive drives, the rod mechanism control shall remain permanently tensioned.
