ADJUSTING THE STEERING PLAY
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.
Remove the inspection hatch (1).

Remove the ring gear (7) and fit the two block wash-
ers (available as spare parts) (8) and (9) under it so
as to place it in a higher position with respect to the
pinion (10), reducing the gap between the teeth.
Reassemble the ring gear matching the two ref-
erences (⇒ ◁), punched on the ring gear (7) and on
the pinion (10), in the drive direction.
Reassemble the nuts (2) and (3), tightening them to
load the cup springs (4) and (5) as much as need to
en sure steering manageability, without creating ex-
ces sive play.
If the addition of a block (8) and another block (9) do
not eliminate the play between ring gear pinion teeths,
replace them since other block may not be ad ded.
