engine manual furnished with this crane.

Replace the Transmission Oil and Filter

1. Engage the parking brake and shut off the engine.

NOTE: It is necessary to climb under the crane to drain the
transmission oil. Be sure engine is shut off, the
ignition key is removed, parking brake is engaged
and chock blocks are in place before climbing
under the crane.

gush out. Keep to one side when you remove the
strainer.
2. Place a suitable container
(Figure 5-41). Remove the strainer and gasket and drain
the oil into the container. Discard the gasket.
NOTE: Before removing the strainer, be sure you have a
new strainer gasket. The old strainer gasket will be
damaged during removal of the strainer, and if it is
installed with the strainer, leakage will occur. It is
recommended that three gaskets be kept in supply
at all times. This will cover a years maintenance
and one for emergency maintenance.
3. Place the container under the drain plug and remove the
drain plug (Figure 5-42). Drain any oil left in the
