If the shaft seal on the flywheel end is to be ex-
changed, it is advisable to exchange the bearing
race too.
Snap the bearing race to be exchanged by apply-
ing a blow with a hammer.
Danger:
Wear goggles and working gloves for
protection against metal fragments.
Caution:
Do not damage flywheel.
Do not use a chisel.

Insert the new bearing race into the pressing man-
drel (special tool, see page 127 , item 14) so that
for the subsequent assembly the internally cham-
fered side faces the flywheel.
Carefully heat the pressing mandrel with the bear-
ing race. The installation temperature for the bear-
ing race is about 150_C (300_ F).
