4.6 ADJUSTING THE STEERING PLAY
Steering play must never be excessive in order not
to effect driving precision.
Check that the steering play is not caused by the
slackening off of the tie-rod system and fully tighten
all the tie-rod and ball joint nuts.
If the play is due to the crown wheel/pinion pairing,
the position of the spacer, fitted to lift the crown
wheel and reduce the gap between the teeth, must
be changed.
To make the adjustment, remove the inspection
hatch, slacken off the register
(1)
and unhook the
spring
(2)
of the traction guide pulley.
Working from the bottom of the machine, unscrew
the nut
(3)
, being careful to adequately support the
crown wheel axle components to prevent them
from unthreading themselves completely.
Remove the screw
(4)
below which the spacer
(5)
is
located.
Remove the crown wheel
(6)
and fit the spacer
(5)
under it so as to place it in a higher position with
respect to the pinion
(7)
, reducing the gap between
the teeth.
Refit the crown wheel
(6)
, matching up reference
(
➜
), punched in the centre, with reference (
❙
) of the
pinion
Refit screw
(4)
and nut
(3)
, tightening it to the pre-
scribed value.
Replace the traction guide pulley spring
(2)
and ...
Adjust the traction engagement [see 4.3].
