Installing the steering bracket
1.

Apply one drop of oil to the first turn of the 

screw thread and to the underside of the bolt 

head. Do not apply more than a single drop 

of oil as excess oil would penetrate between 

the two contact surfaces, which would 

increase the risk of the connection 

loosening.

2.

Screw the nut on the attachment bolt by 

hand. If the nut can be screwed by hand 

easily on to the bolt, the bolt may be re-used. 

If necessary, the attachment bolts should be 

renewed.

3.

Remove all paint from the contact surfaces 

of the steering box/steering bracket and 

steering bracket/chassis (a thin, factory-

applied layer of paint is allowed).

The contact surfaces should be absolutely 

free from dirt and grease.

4.

Place the steering bracket on the chassis. 

Tighten the bolts evenly to the specified 

tightening torque. See 'Technical data'.

5.

Install the steering box.

4.3 REMOVAL AND INSTALLATION, PITMAN ARM

If the pitman arm has been subjected 

to extremely high loads (accident), it 

should be magnaflux tested, even if 

no deviations can be found with the 

naked eye. If such a test is not 

possible, the pitman arm should be 

replaced at all times.

The pitman arm should only be 

removed using the prescribed 

special tools. Under no 

circumstances should the pitman 

arm be removed by dislodging it with 

a hammer or by heating, if the 

prescribed tools are not available. 

This would not only result in the 

pitman arm becoming highly 

unreliable, it would also permanently 

damage the sector shaft.

Removing the pitman arm
1.

Remove the steering box.

2.

Clean the screw thread of the sector shaft 

protruding from the nut.

3.

Tap the locking ring of the nut back into its 

locking position.

4.

Remove the nut from the sector shaft.

5.

Place the push rod (see arrow in drawing) in 

the hydraulic puller (C), special tool 

(DAF no. 0535891).

6.

Screw the adapter (B), special tool 

(DAF no. 0694786), partly onto the hydraulic 

puller (C).

7.

Slide the claw (A), special tool 

(DAF no. 0694916), over the pitman arm (1).

If necessary, cut the sector shaft dust 

seal (2) and remove it.

8.

Slide the adapter (B) with the hydraulic 

puller (C) into the claw (A).

9.

Screw out the spindle (D) of the hydraulic 

puller (C) as far as possible. Subsequently 

screw the hydraulic puller (C) into 

adapter (B) as far as possible using an open-

end spanner.

10. Screw in the spindle (D) until the pitman arm 

comes off the sector shaft.

If the pitman arm still has not come off after 

the spindle has been completely screwed in, 

screw out the spindle and screw the puller 

into the adapter (B) as far as possible. Then 

screw in spindle (D) again until the pitman 

arm comes off.

Installing the pitman arm
1.

Install a new dust seal on the sector shaft.

2.

Grease the dust seal surface which is 

positioned against the steering box using a 

grease with the specified DAF specification 

(melting point >130 

C).

3.

Install the pitman arm on the sector shaft so 

that the marks on the pitman arm and the 

sector shaft align.

Note:

As the sector shaft is normally secured at the 

same position, the sector shaft nut can only 

be secured twice. After that, the nut should 

be replaced. The nut should not be used for 

locking at locations where the shaft has 

already been locked before.

4.

Block the steering box with the pitman arm.

Do this, for example by fixing a section of a 

used steering rod to a clamp and to the 

pitman arm with the ball joint.

If the pitman arm is blocked differently, 

ensure that the conical section of the pitman 

arm is not damaged.

Note:

If the steering box is not blocked, the 

adjustment of the wheel-deflection limiting 

valve will be distorted when the steering box 

is completely rotated in.

5.

Fit the nut on the sector shaft and tighten it to 

the specified tightening torque. See 

'Technical data'.

6.

Secure the sector shaft nut by tapping the 

locking ring of the nut at least 2.5 mm into 

one of the recesses of the sector shaft.

Always use a part of the locking ring which 

has not been used before.

7.

Install the steering box.
