a. Heat the area of the lower case where the
tapered roller bearing outer race is to be
removed using a gas torch, and then re-
move the tapered roller bearing outer race

shaft sleeve "3".
When heating the lower case, heat the en-
tire installation area evenly. Otherwise, the
paint on the lower case could be burned.

er race "1", place some cushioning material
under the lower case to catch the outer race
when it falls out.
• If the taper roller bearing outer race does not
come out, lightly tap the lower case with a
plastic hammer.
