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
"1" and forward gear shim(s) "2".
When heating the lower case, heat the en-
tire installation area evenly. Otherwise, the
paint on the lower case could be burned.
TIP:
• Before removing the taper roller bearing out-
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 torpedo
with a plastic hammer.
