STEERING ASSEMBLY

PUSHER ADJUSTMENT

The pusher clearance adjustment shall be performed taking into account the wear

degree of the following parts: rack, pusher, casing.

The adjustment method shall be

observed every time it is necessary to alter
the spacers clearance,  in order to maintain
a normal operation of the steering gear box.

1

. Cap

2

. Elastic washer

3

. Sprig

4

. Adjustment washer

5

. Pusher

The operation shall be performed after

removing the steering gear box off the
vehicle.

ADJUSTMENT METHOD

Clamp the steering gear box in the vice.
Dismount:

- the pusher cap (1);
- the adjustment washers (4);
- the elastic washer (2);
- the spring (3);
- the pusher (5).

Carefully clean the pusher seat and the parts that have been dismounted.
Grease the parts with special grease containing MoS2.
Mount the parts in the pusher seat, except for the elastic washer.
Make a comparator support out of an old cap.

NOTE: Do not rotate the drive pinion while the cap is dismounted.

PUSHER ADJUSTMENT

MEASUREMENT OF THE FREE HEIGHT “ H “

OF THE ELASTIC WASHER

Place the washer on a straight plate and

measure its height by means of a comparator,
using a set of spacers with a known thickness.

Note the average value.

RACK WEAR CHECKING

The rack wear degree is established by

measuring the difference between the maximum
and minimum values  on the rack, in the central
area.

Attach the comparator support instead of

the cap.

Bring the feeler in contact with the pusher.

Mark points A and B in the central area of

the rack, corresponding to the box extremity.

The measurements are always performed

from point (A) towards point (B).

Bring the rack to point (A)  and set the

comparator to zero.

Slowly move the rack until it reaches point

(B).

Bring the rack back to point (A).

STEERING ASSEMBLY

Move the rack up to the point where the value is the highest.
In this point, reset the comparator to zero.

MEASUREMENT OF DISTANCE ( D ) ABOVE THE PUSHER

In the position previously set, rotate the rack by means of a fixed wrench, without

forcing, until the pusher comes into contact with the adjustment washers;the rotation must
be done in both directions.

Read the displacement value on the comparator and note the highest value.

PUSHER ADJUSTMENT

SETTING OF THE ADJUSTMENT WASHERS THICKNESS

The thickness of the adjustment washers shall be measured for the lowest point of the

rack, so that a pre compression of the washer is obtained:

E = ( D + 0,06 mm ) - H
E 

 - washers thickness;

D 

 - the distance above the pusher;

H

  - the free height of the elastic washer;

0,06

 - pre compression of the washer.

In order to obtain an adequate thickness

which may be obtained from the existing
washers, diminish the calculated value by
0,04 mm

.

On remounting, place the elastic washer (2) in contact with the pusher (5) and the

adjustment washers (4), in contact with the cap (1).

Observe the mounting sense of the elastic washer.
Place the set of washers, established by measurement above the pusher.

C

H ECKING

Place the set of the washers, established by measurement, above the pusher.
Measure the distance between the pusher

and the adjustment washers; this distance
should be equal to the free height  of the elastic
washer, minus 0.02-0.06mm.
   If this value is not obtained, measure again.

Dismount the comparator support.
Remove the adjustment washers.
Put special grease, containing MoS2, in the

seat.

Remount:

- the elastic washer;
- the adjustment washers;
- the cap.

Tighten the  cap attachment screws  at the

required moment.
