STEERING COLUMN, AND HYDRAULIC CONTROL UNIT

Downloaded from www.Manualslib.com manuals search engine b) Control unit : ’
The contra! unit located below the steering wheel, consists of a distributor slide-valve ( C ) which. when
hydraulic pressure on either side of it is the same ensures in chamber 1 the necessary pressure for the
steerinq piston

Movement of rack causes movement of its control pinion. pinion B and pinion D Pinion F being then locked in posi-
tion, pinion D acts on rockers E. which in turn brinq back slide-valve C to its position of equilibrium.
NOTES :
1) Manual operation is ensured by shaft A being mechanically connected to pinion B after cancellation of clearance
a J )).
2) The steering rack is hydraulically locked for any steering position, which ensures great directional stability of
the vehicle.

IV. ADJUSTING THE STOPLAMP SWITCH
1.
Check adjustment of free play on brake pedal ( see above ).
2. Adiusting the stoplamp
The stoplamps must light as soon as the pedal contacts the brake valve.

1.
Raise front of vehicle ( wheels free ).
Remove front wheels.
Release handbrake lever to maximum extent 2. Adjust eccentrics :
a) Remove adjustment nuts ( 1 ) and lock-nuts (2.)
for handbrake cables.
b ) O,,,‘varh hmokt~ ,,rzit :
Slacken SCI~WS (4) of eccentrics ( 6 ). Ensure
With spanner 6501-T turn eccentrics as shown f rrpu,ards ) until the pads just contact the disc
at point of maximum run-out.
Tighten screws (4) from 6 to 6.5 daNm (43 l/2
to 47 ft.lb ).
Check correct contact of pads.
Screw down stop SCI~W (3) until it contacts
the brake unit housing ( tighfrn its lock EN! 1, 3. Adjusting hondbrake control cables :
, On rnrh hrnkc ,,,, if:
Ensure correctly positioned.
Pull alfcmnf~~iy on each threaded end-piece (7 )
ond measure its protrusion (< c 1).
.Example : Protrusion on right-hand side = 30 mm
Protrusion on left-hand side = 26mm Difference in length of cable must remain the
some after adiuitment.
