The stopscrew for 3rd gear can be adjusted SK the vehicle.
Carry this out as follows : Slacken locknut ( 1 ) and stopscrew (2 ). Engage 3rd gear. Bring stop-screw i 2 1 into
contact with the selector shaft. and tighten l/2 a turn, which affords a clearance of a.4 to Cl.7 mm.
Tighten lockfiut ( 1) and disengage gear.
NOTE : Adjusting the stop-screw for 2nd gear
con only be carried out with the gearbox removed
from the vehicle. To adjust it, proceed in exactly I
the same manner as for 3rd gear. Checking and adjusting the contacts :
1.
Remove cover ( 3) from the switch unit controliinq
the electro-valve. 2. Check adjustment of contact gaps :
Proceed in the same way far each of the 4 contacts.
a) Engage a gear.
WARNING In order to obtain correct opening
of a contact, the corresponding gear must be
fully engaged. otherwise the adjustment would
not be correct.
b) Check the contact gap corresponding to the
gear engaged, using a set of feeler gauges : Contact gap :
2nd
and 3rd gears 0.8 to 1.1 mm
1st and Reverse 1.3 ? 0.2 mm
c 1 Adjust the contact by slackening screw ( 5)
on the fixed contact (4 mm Allen key ) and
move this contact along its slot.
Tighten screw ( 5) from 0.35 to 0.4 doNm
( 2 l/2 to 3 ft.Ib ).
IMPORTANT : This adjustment must be carried
out with precision, otherwise, the clutch might
disengage at times without the gear lever
having been touched.

8. Checking the hydraulic brake contml :
m ) Tighten pressure regulator bleed screw.
b) Start up engine.
When cut-out takes place wait a fen: seconds
for the pressure to stobilize.
Stop engine%
Watch pressure gauge and note the pressure
drop in the next 3
minutes. If pressure drop
exceeds 10 bors*( 145 psi ) repeat the test.
If the re< is the same. the broke control
valve is defective : change it.

Downloaded from www.Manualslib.com manuals search engine 9. Checking pressure switch (1) : Test procedure is the sctme as for checking
broke control.
Turn engine to obtain cut-out pressure.
Stop engine.
Operate brake pedal until the hydraulic pressure
warning lamp remains on.
Attbat point, read off pressure on pressure gauge.
This should be between 75
and 95 bars ( 1088 ta.
1378 psi 1, inclusive.
If not, change the pressure switch.
10. Checking the Front suspension : Slacken.pressure regulator bleed screw.
Remove plug E and connect front suspension
supply pipe (2 ) to safety valve.
Tighten pressure regulator bleed screw.
Start engine.
Put manual height control in
rronnaf rtmni>rp positim. Wait until the front end of vehicle rises and cut-
out takes place.
Allow pressure to stabilize.
Stop engine.
Examine pressure gauge and note pressure drop
during wperiod of 3
minutes. If it exceeds 10 bars
( 145 psi 1, check once more.
If the result is confirmed check the following
c?mponenG to determine which one is leaking :
either the front corrector
or the suspension cylinders (one or both ).
Testing the 3 components should be carried out by
eliminating each one in turn.
(I) Testing the front height cmwclor : Loosen pressure regulator bleed saew.
Put manual control in
loin position. Disconnect supply pipe (3 ) for front cylinders
from 3-way union (4 ).

Read off pressure drop on pressure qtruqe.
If this drop in pressure is greater than
10 bars (
145 psi ) during a period of 3 minutes, repeat
test. If the result is confirmed, the front height
corrector is defective : change it.
