2. SEALS

2.1 REMOVING AND FITTING SEALS

There are two kinds of seals: conventional seals
and unitised seals.
-

The conventional seal is fitted in a recess
and its inner ring has its running surface on
a shaft.

-

The unitised seal is fitted in a fixed position
both in a recess and on the shaft. Sealing is
achieved internally.

Removing the seal

1.

If possible, remove the sealing ring with the
special tool (DAF no. 1329458 or
DAF nos. 0694928 (A) and 0484899 (B)).
When removing the seal, take care not to
damage the recess.
