Installing the sector shaft oil seal on the 
pitman arm side
1.

Fit a new sector shaft oil seal (2) in the 

steering box (3) using special tool 

(DAF no. 1329453).

2.

Apply clean grease with the specified DAF 

specification (melting point >130

C) to the 

needle bearing (4).

3.

Apply grease with the specified DAF 

specification (melting point >130

C) to the 

rear side of the new dirt/water seal (5) and fit 

the dirt/water seal (5) into the steering box..

4.

Stick adhesive tape to the sector shaft 

groove teeth (1) (see arrow in drawing). This 

tape will prevent damage to the sector shaft 

oil seal when fitting the sector shaft in the 

steering box.

5.

Check whether the piston is still in its central 

position, so that the middle sector shaft tooth 

engages the correct piston teeth.

If the piston is not in its central 

position during the sector shaft 

assembly, the steering turn to one 

side will become very small. This 

may lead to dangerous situations.

6.

Install the sector shaft (1) into the steering 

box (3).
