Assembling the lower case
•Use heat-resistant gloves. Otherwise,
burns could result.
•To prevent fires, remove any flammable
substances, such as gasoline and oil,
around the working area.
•Keep good ventilation while working.
1. Install the original forward gear shims “1”.
2. Heat the area of the lower case where
the taper roller bearing outer race is to be
installed using a gas torch, and then
install a new taper roller bearing outer
race “2”.
When heating the lower case, heat the
entire installation area evenly. Otherwise,
the paint on the lower case could be
burned.
TIP:
Do not reuse a shim if deformed or
scratched.
3. While holding the special service tool “1”,
strike the tool to check that the taper
roller bearing outer race is installed prop-
erly.
TIP:
If a high-pitched metallic sound is produced
when the special service tool is struck, the
outer race is installed properly.
