BRAKE CONNECTIONS AND SEWERAGE
The sewera ge connection between the brake pump, bra ke calipers, pressure limiter is
performed by m eans of the t hreaded connections with METRIC PITCH.Therefore it is
important to use onl y original spare pa rts, recommended in the Spare Parts Catalogue,
specific for this type of ve hicle.

The shock absorbers are stored in t he spare

In these conditions, it is possible that shock
absorbers working vertically, to get depressed.
Therefore, before mounting on the vehicle, it
is sufficient to perform the shock absorbers
pressing, by alternatively shifting the shock
absorber rod (upwards a nd downwards), the
shock absorber being in vertical position. S

DISMOUNTING Place t he locking clamp of t he SUS 600
device in order to maintain the spring
compressed. Loosen the screws of the wheel on the side
where the dismounting is performed.
Dismount the wheel.
Di smount the shock absorber lower attach-
ment nut and screw. Push the axle and remove the spring.
REMOUNTING
Pe rform in reverse order the dismounting operations.

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.

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)
