Clean the flywheel and the starter ring gear. 

Ensure that the contact areas are free of 

grease.

2.

Heat the new starter ring gear evenly in an 

oven. See "Technical data".

3.

Tap the starter ring gear onto the flywheel so 

that the bevelled sides of the teeth point 

towards the starter motor. Ensure that the 

starter ring gear is properly fitted to the

4.18 REMOVAL AND INSTALLATION, FLYWHEEL HOUSING SEAL

Note:

A new oil seal is fitted on a plastic mounting ring. 

The oil seal must not be removed from the 

mounting ring until the oil seal ring has been 

pressed into the flywheel housing by hand.

Removing the flywheel housing seal
1.

Remove the flywheel.

2.

Drill two small holes into the oil seal and pull 

the latter out of the flywheel housing using 

the special tool (DAF no. 0484899 en 

0694928).

Installing the flywheel housing seal
1.

Thoroughly clean the oil seal recess and 

inspect for damage. Even the slightest 

damage can cause a leak.

2.

Clean the crankshaft flange.

Note:

If a shim was fitted in the seal recess, it must 

be re-fitted.

3.

Fit the plastic mounting ring (1), with the oil 

seal dry, to the crankshaft flange.

4.

Press the oil seal (2) as far as possible into 

the recess by hand and then carefully 

remove the plastic mounting ring (1).

5.

Fit the base plate (A) of the special tool 

(DAF no. 0535598) on the crankshaft flange.

6.

Place the thrust washer (B) over the base 

plate (A) and gradually tighten the nut (C) 

until the resistance increases.

7.

Remove the nut (C) and thrust washer (B).

8.

Make sure that the entire oil seal is 

positioned evenly in the recess. If not, fit the 

thrust washer (B) again and tighten the oil 

seal a little further with the nut (C).

9.

Remove the base plate (A).

10. Fit the flywheel and tighten the bolts to the
