2. While the lubricant is at operating temperature, remove
the drain plugs from the axle bowls and drain the lubricant.
NOTE: Each of the wheel planetaries must be drained
separately. The following procedure is the same for each
wheel planetary.
3. Position the wheel with the planetary drain plug at the
lowest point.
4. Remove the planetary drain plug and allow the planetary
to drain completely.
5. Install the axle bowl drain plugs.
6. Position the machine so the plug hole in one of the
planetaries is either right or left on the axle horizontal center
line. Refer to Illust, 5.
7. Install the plug in the planetary on the other side of the
machine.
8. Fill the axle with fresh lubricant through the open
planetary hole up to the bottom of the hole. Refer to
"LUBRICANT

this section for the type of lubricant specified.
