Case 688 overview

Engine

Fast, simplified servicing

All routine servicing can be done from groundline or from the service walkway behind the cab. A tilt-up door and removable side panel provide easy access to the engine.


Hydraulic and electronic system

Closed-center, load-sensing, constant hp hydraulic system

The load-sensing hydraulic system of the 688 supplies hydraulic flow to meet the needs of various functions on demand, while maintaining constant, efficient engine speed. The unique, main component of the system is two concentric pumps within one housing. An outer, variable-displacement piston pump meters flow on demand to the boom, dipper, bucket, travel and auxiliary functions. This variable pump accommodates load demands by changing displacement. It can also go to zero stroke at maximum pressure to prevent energy loss over the relief valve. The inner pump is a fixed-displacement unit dedicated to the independent operation of the swing system. As shown, a separate pump supplies the pilot and accessory systems. The result is hydraulic power when and where you need it for optimum productivity.


Undercarriage

Advanced electronics

A compact instrument module incorporates the latest in printed circuit technology. Switches, lights and gauges are all located in a pedestal at the operator's fingertips.


Upper Structure

Powerful final drives

Low-torque, high-speed axial piston motors with triple planetary reduction gears supply power to the track drive sprockets. The system includes an automatic speed limiter and disc brakes. Additionally, motors and tubelines are protected by a compact design and guarding.


Cab

Operator comfort

Two power-assist control levers reduce operator fatigue. A deluxe suspension seat is adjustable to operator weight and height. Raising the left-hand console cuts oil flow to all hydraulic controls, providing protection when the operator leaves the machine.


High-visibility cab

An all-steel cab features a one-piece floor-to-ceiling windshield which easily slides open and stores in an up-and-over position. All windows are of generous size for visibility in all directions and are made of tinted safety glass.
