Remove & Install Final Drives
Start By:
a. separate track assemblies
At operating temperature, the hydraulic oil tank is hot and under
pressure. Hot oil can cause burns. To prevent possible personal injury,
release the pressure in the implement hydraulic circuits (boom, stick
and bucket) before any hydraulic lines or components are disconnected
or removed.
1. Release the pressure in the hydraulic system as follows:
a. Fully retract the rod in the stick cylinder.
b. Adjust the position of the bucket so it will be flat on the ground when the boom is lowered.
c. Lower the boom until the bucket is flat on the ground.
d. Shut off the engine, and put the hydraulic activation control lever in the "Lock" position.
