16. TRAVEL REDUCTION GEARS MAIN COMPONENTS The CX75SR, CX80 and CX135SR are fully hydraulic machines. They consist of an undercarriage fitted with tracks and a turntable bearing which supports the upperstructure frame. The upperstructure frame supports the attachment, at the front end of the machine, plus the engine, hydraulics and cab. When the operator works the controls, the engine-driven pump delivers hydraulic fluid to the control valves.
Page 10 CHAPTER 1 - GENERAL INFORMATION RIGHT, LEFT, FRONT AND REAR OF THE MACHINE The terms Right-hand, Left-left, Front, and Rear are used in this manual to indicate the sides as they are seen from the operator's seat when the cab is over the idler wheels.
