four steps, as shown below:
1.Use tool A, apply a force in the direction of the
arrow, squeeze the tool between the oil seal and
the engaging surface of the groove;
2. Apply a force in the direction as shown in the fi g-
ure, initially thrust the oil seal out of the groove
with tool, if necessary, stab the oil seal with tool C
and then thrust it;
3. Apply a force in the direction of the arrow as sho-
wn in the fi gure, thrust the oil seal completely out
of the groove;
4. Go on thrusting tool A and turn it for 180°, draw
and prick to remove the oil seal fi nally.
