System Pressure - Release".
B. Remove the track. Refer to Disassembly and Assembly, "Track - Remove and Install".
C. Remove the final drive sprocket. Refer to Disassembly and Assembly, "Final Drive

Personal injury can result from hydraulic oil pressure and hot oil.
Hydraulic oil pressure can remain in the hydraulic system after the
engine has been stopped. Serious injury can be caused if this pressure is
not released before any service is done on the hydraulic system.
Make sure all of the attachments have been lowered, oil is cool before
removing any components or lines. Remove the oil filler cap only when
the engine is stopped, and the filler cap is cool enough to touch with
your bare hand.
