DISMOUNTIN G
Dismount the two maintaining collars off
the bellows by means of two rods, locally
manufactured (see the drawing)
Cut and remove the damaged bellows.
Remove as much grease as possible.
Mark one of the groove routes of the shaft
subject to its working corresponding clog by
marking w ith a centre punch on casing outer
conse quently on the shaft.
Detach th e connection be twe en the
transmission shaft and the steering knuckle
casing, lift ing one by one the arms of the
reta ining star from the three stamps performed
on the petals of the shaft tulip.

REMOUNTING
The mounting of the new bellows is to be
performed by means of the PF 573 – 04 device.
Catch the inclined transmission in a vice with
soft jaws in order to avoid the shaft damaging.
Engage the PF 537 – 04 device over the tulip
of the transmission shaft.
O bturate the small e xtremity of the bellows
and, abundantly grease with automatic
transmission oil or ELF CARDREXA RNT 2
grease: - the all outer surface of the PF 537 – 04
device, - the inner part of the bellows, especially its
smaller diameter part (this operation is performed
for slipping help).

Catch the steering knuc kle c asing in a vice
with soft jaws. Put the spring and head in the tripod groove.
Brings the clogs to the center.
Position the retaining star ( S), and each of its
arms, being at the bisecting lines of the a ngles
formed by the tripod arms.
Introduce the transmission shaft in the steering
knuckle casing, positioning it, subject to the
marks (the t hree c logs penetra ting in the t hree
rolling routes of the shaft). Slide slowly the t ransmission shaft, in order
to engage one arm of the retaining star in the
marked point of the transmission shaft, and press
it for correct centering.
Placing the other retaining star t wo arms, it
will be made easy by a screwdriver, with its end
modified as per drawing:
A = 5 mm B = 3 mm
Ensure that retaining star arms are correctly
positioned in the shaft marks.
Check by hand, the joint operation.
Must not exist any hard point.
Di stribute in the bellows and in the steering
knuckle casing the grease prescribed dosage.
NOTE It is obligatory to observe the quantity
and type of the prescribed grease, 2 l
+1 cl,
ELF CARDREXA RNT 2.

Position the two bellows beads in the grooves of the steering knuckle casing, consequently on
the transmission shaft tube.
P lace a non-cutting, round headed rod between the transmission shaft and the bellows in
order to dose the amount of air inside. Mount the two collars, by means of the two rods used also at the dismounting operation.

Using a press, extract the assembled tripod, sustain it on an extractor type FACOM U 53 G,
protecting the clogs of the tripod.
R EMOU NT I NG
Grease the transmission shaft to help the protection bellows putting back (positioning of the
smallest diameter of the bellows on the transmission shaft).
The tripod is fixed and mounted in the position marked on dismounting.
Three poi nts of crimping are made at 120 ° C by metal he ading of t he t ransmission shaft
grooves.
Distribute the grease prescribed quantity in the bellows and in the tulip casing.
Correctly position the bellows in the tulip-casing place.
A non-cutting, round-headed rod is introduced between the bellows and the tulip casing to
dose the air amount contained inside the bellows. Lengthen or compress the bellows until value A = 190 mm is obtained (the value between
the extremity of the bellows and the extremity of the tulip casing) then from this position extract
the rod and remount the collars.

Chara cteristics
The front axle is composed of two joint half axles with independents wheels, designed for the
suspension type Mc.Pherson.
The joints of front half axle arm are done by means of an elastic bearing (chassis side) and by
means of a suspension ball joint (wheel side)
The transmission of the motion to the wheels is done by means of two planetary a xles, not
equal, with homocinetic tripod joints.
The wheel hub is assembled in the steering knuckle by means of a sealed bearing.
The brake disks a re ventilated.
