- Torque converter with incorporated disc clutch. Make FERODO ( VERTO system ). Type 697 ( CX 2200 )
or 693 ( CX 2400 ).
_ Clutch engagement and disengagement are controlled by a hydraulic system with an electro valve unit
I This electro-va,lve is itself controlled by an electric switch operated by the gearbox selector shafts.
- Conversion ratio of converter 2 30 1 ( 697 type )
2.20 1 ( 693 type ) II. SPECIAL FEATURES
Adiustments :
- Contact gap in electric switch unit ,controlling the electro-valve
NOTE The gap for the 2nd/ 3rd gear contacts must only be adjusted once the selector shaft stop-screws have
been adjusted ( See Op. MA. 330-00 ),
- Gap at 2nd/ 3rd gear contacts 0 8 to 1.1 mm

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
