( 3)
With the steering wheel in the mid-
position, move the steering gear arm back
and forth to determine whether or· not there
is any backlash.
If
there is more than 1/32
inch free .movement, the gear should be
adjusted.
( 4)
To adjust, refer to figure 1. Re-
move the lock nut (
2 )
and slide off the lock
plate (3).
( 5)
Tighten the roller tooth shaft ad-
justment screw ( 1 ) just enough to eliminate
the free play between the roller tooth shaft
and the worm.
( 6)
Slide the lock plate ( 3) in position
against the roller tooth shaft cover and
lock it.
( 7)
Install and tighten the lock nut
(2 ).
(8)
Test adjustment by rotating the

arm, with the two ,tie rods assembled, from
the steering gear shaft and install another
arm.

mid-position. To do this, turn the wheel
from extreme right or left to the opposite ex-
treme, counting the number of turns re-
quired. Then turn the wheel back
1 /2
the
number of turns required to turn the wheel

With the steering wheel in the
mid-position, move the steering gear arm
back and forth to determine whether or not
there is any backlash.
If
there is more than
1/32 inch free movement, the gear should
be adjusted.

To adjust, refer to figure 2. Re-
move the steering arm and the shaft cover.
( 5)
Remove the roller tooth shaft
(steering arm shaft) from the housing and
remove a shim from the shaft. (Shims are
used to prevent the roller tooth pressing too

install the cover. Before tightening the cover,
loosen the adjusting screw ( 1 ) in the cover
about two full turns, then tighten the cover.

and then back it off just enough to eliminate
drag when rotating the steering wheel. Lock
the adjusting screw with lock nut.
