4.

Slide the flange off the output shaft or, if 

necessary, use a tripod puller to pull it off the 

shaft.

5.

Drill two holes in the external cover of the oil 

seal and turn special tool (DAF no. 0484899) 

into the oil seal. Pull the oil seal out of the 

gearbox housing using special tool 

(DAF no. 0694928).

Installing output shaft oil seal
1.

Apply a small amount of liquid gasket to the 

outside of oil seals fitted with a steel cover.

Apply a small amount of green soap to the 

outside of oil seals fitted with a rubber cover.

2.

Fit the oil seal in the gearbox housing using 

special tool (DAF no. 1240037).

3.

Apply a small amount of grease to the oil seal 

lips and slide the flange over the output shaft 

until it abuts.

4.

Fit new sealing rings (2, 3) to the locking 

plate and fit it with the attachment bolt to the 

flange (apply a small amount of grease to the 

sealing rings).

Note:

The attachment bolts on the new gearboxes 

are no longer secured by a locking plate, but 

by the self-locking screw thread in the output 

shaft.

5.

Hold the prop shaft flange in place with the 

special tool (DAF no. 0484977).

6.

Tighten the attachment bolt (5) to the 

specified torque. See "Technical data".

If the locking plate is not tightened to 

the specified torque, there is a risk of 

it getting bent during fitting, which 

could lead to serious oil leakage.
