Steering column
Tilt steering column can be adjusted to five different positions for operator comfort and control。
Chair
Suspension seats provide a comfortable driving experience。
Electronic monitoring system
The electronic monitoring system checks critical machine systems and provides three levels of warnings。
Radio
The operator station in the cab has reserved wiring for the radio。
Characteristic
657E Standard cab features include air conditioning for operator comfort and efficiency, and turn signal lights。
Serviceability
Fuel tank
Fuel tank mounted on scraper for easy access to tractor engine compartment。
Wiring harness
Wiring harnesses incorporate color coding and numbered circuits for quick identification，Also comes with at least 10 A Fuse and improved connector。
Diagnostic connector
With the help of a service tool，Starting and charging circuits can be quickly analyzed using the diagnostic connector。
O V-shaped sealing ring end face seal
O V-ring face seals help prevent oil leakage on these machine。
Centralized lubrication points
Centralized lubrication points for hitch and steering reduce lubrication times。
Repair and maintenance points
The engine service points are concentrated on the right side.，And is easy to overhaul。
Maintenance platform
Access platform and numerous handrails for ease of maintenance and safety。
Parts availability
Improved components and other Caterpillar Scraper/Commonality between machines，Improved parts availability。
Engine shutdown
Electronic ground engine shutdown provides convenient operator and service area。
Radiator
Folded core radiators allow individual folded cores to be replaced as modules，Reduced maintenance time，And that cost is reduce。
Reliability
Reducer
When the machine is operating on a steep slope，Hydraulic retarders extend brake life。
Bumper
Bumper edges are rounded，Avoid hooking into high walls。
Casting
Rack、Castings are widely used in articulated parts and bucket，A long service life is achieved.。
Wiring Harness and Hose As
The wiring harness and hose assemblies extend all the way to the tow arm，Eliminate the need for jumper lines that could reduce the efficiency of the hydraulic system。
