25 Unscrew the union nut and detach the
hydraulic fluid line from the operating cylinder
(photo).
26 Undo the cylinder/mounting bracket
retaining bolts and lift clear the cylinder
together with the bracket (photo). Release the
retaining clip and separate the cylinder from
the bracket.
27 To dismantle the cylinder, prise free and
pull back the dust boot, withdrawing it
together with the operating rod.
28 Invert the cylinder and shake free the
piston and seal assembly. If it is stuck inside
the cylinder, remove the bleed screw then
apply moderate air pressure (from a foot
pump) into the bleed port and catch the
cylinder in a clean cloth as it is ejected.
29 Remove the seals noting their orientation.
Clean all components in methylated spirits or
new hydraulic fluid. If the cylinder is damaged,
scored or badly worn it must be renewed. The
seals must always be renewed once they are
removed.
30 Assemble the new seals to the piston and
lubricate the cylinder, seals and piston
assembly with new hydraulic fluid (of the
specified type) before assembling them.
Ensure that the seals are fitted the correct
way round (as noted during removal).
31 Renew the dust boot, fit and secure the
operating rod into position then refit the dust
boot over the cylinder. If removed, refit the
bleed screw.
32 Reconnect the cylinder to the mounting
bracket and refit the combined assembly to
the vehicle in the reverse order of removal.
Ensure the hydraulic union is clean and take
care not to damage the threads as it is
reconnected.
33 Remove the polythene seal from the
hydraulic reservoir filler neck, top up the fluid
level and bleed the system as described
below.
Clutch hydraulic system -
bleeding #
34 The clutch hydraulic circuit is bled in
much the same manner to that described for a
brake circuit. Refer to Section 12 in Chapter 8
and proceed as described, but note that the
bleed screw for the clutch circuit is located in
the end of the operating cylinder (see
photo 11.25). The clutch hydraulic circuit
reservoir is mounted in the engine
compartment on the left-hand side near the
bulkhead and is separate from the master
cylinder. As the system is being bled, ensure
that the fluid level in the reservoir is
maintained between the MIN and MAX level
marks. Do not allow the fluid level to drop
below the MIN level mark otherwise air will
enter the system and greatly lengthen the
operation. Wipe clean any fluid spillage from
the paintwork or adjacent components as it
has a corrosive effect if left.
12 Transmission
PART A:
1301 CC TURBO IE ENGINE
Description
1 The transmission is of five-speed type,
based on that used in the Fiat Strada 105 TC.
2 For all practical purposes, the operations
described in Chapter 6 apply, but observe the
following differences.
Gearchange linkage -
removal and refitting ¡
3 This is of two-rod type.
4 Remove the gaiter and disconnect the rods
at the gear lever end as described in Chap-
ter 6, Section 3.
5 Disconnect the rods at the transmission
end by unscrewing the nuts and bolts which
connect the linkage rods to the selector rods
(photo).
6 Extract the spring clip which retains the end
of the short link rod (photo).
Gearchange linkage
(Antiskid models) - general
7 The gearchange linkage and internal
selector arrangement has been modified, as
shown in Fig. 13.89.
Final drive output shafts -
description and
oil seal renewal #
8 The output shafts on this transmission
incorporate a flange on the left-hand side, to
which a coupling flange on the driveshaft is
bolted. On the right-hand side, an
intermediate shaft (see Section 13) is splined
directly into the differential side gear.
9 A leaking oil seal may be renewed on the
left-hand side of the final drive casing after
first disconnecting the driveshaft. Then using
two levers, prise out the flange/stub shaft
against the tension of its retaining circlip.
10 Unbolt and remove the bearing cover.
When refitting the cover, make sure that the
O-ring is in good condition.
11 To renew the oil seal on the right-hand
side, first remove the intermediate driveshaft,
and then prise the defective seal out of the
final drive housing using a suitable tool.
12 Apply grease to the new seal lips before
refitting the intermediate shaft or the stub
shaft. Tighten all bolts to the specified torque.
PART B:
1372 CC IE AND 1372 CC
TURBO IE ENGINES
Description
1 The transmission is of five-speed type,
based on that used in the FIAT Tipo. The
transmission is mounted in-line with the
engine and is located in the left-hand side of
the engine compartment. Drive from the
clutch is transferred through the input shaft
and the mainshaft to the integrally-located
