Caterpillar WHEEL TRACTOR-SCRAPER 657G - catalog of spare parts
Quick loading, high travel speeds and the ability to load and dump on the run yield fast cycle times, allowing the Cat 657E Coal Scraper to consistently deliver high productivity at the lowest cost per ton. The fuel system and the electronic control unit on the engine of the C18 tractor economically and accurately deliver fuel. High injection pressure, independent of engine speed, reduces smoke and emissions while improving response.
Choose WHEEL TRACTOR-SCRAPER 657G section:
Engine
Cat proven engines provide increased power and torque for superior traction in heavy load conditions.
Variable time injection
Variable injection times and durations improve fuel efficiency and cold start, reduce smoke and emissions.
Form speed injection
Forming injection speed reduces engine emissions and noise.
Mechanical parts
Fewer mechanical parts in the fuel system increase reliability.
Electronic control
Electronic control provides automatic height reduction and automatic limitation of the air filter.
Ratings of several horses
Rated power in several horsepower limits power in the first and second gears.
Neutral start control
Neutral start control prevents the engine from starting if the gearbox is not in neutral.
Reserve management
Backing up the throttle provides the operator with pre-set engine speed control in the event of a throttle inlet failure.
Block
Throttle lock allows the operator to block both engines at any operating level.
Directed shift management
Directional shift control prevents the operator from switching from neutral when engine speed is above a predetermined level.
Drived engine motion
Controlled throttle shifting increases transmission life by reducing fuel injection speed just before shifting.
Automatic other start
An automatic auxiliary launcher of the ether significantly improves the launch in cold weather.
Disable earth electronic level
Electronic trip at ground level allows the operator to stop the engine from the ground with a flick of a switch.
Steel spacer plate
A steel spacer plate between the block and the head eliminates the need for countersinks and helps prevent cracking problems.
Cooling oils
Oil-cooled pistons and full-size water-cooled sleeves maximize heat transfer for longer component life.
Subcooler
An additional cooler reduces the intake air temperature to increase power and reduce thermal stresses, which can cause premature wear of pistons, rings and liners.
Engine oil
The engine oil cooler maintains the optimum oil temperature for proper cooling and longer lubrication life.
Laminated thermal protection
Laminated heat shield improves the protection of the tractor by reducing the temperature of the open surfaces of the engine, cools the engine and working compartments, increases the service life of hoses and wiring.
Standard hydraulic retarder
An optional hydraulic retarder can extend brake life.
Transmission
An eight-speed, power shift transmission provides automatic on-the-go shifting for easy, reliable operation.
Neutral control of the coast inhibitor
Controlling a neutral coast inhibitor helps prevent shifting to a neutral gear at speeds above 8.1 km / h (5 mph).
Top gear control
Top-drive control helps prevent shifting above the programmed gear in order to better control the speed on the road.
Electronic programmable transmission control (eptc ii)
Electronic Programmable Transmission Control (EPTC II) records both current and intermittent faults.
Design
The electronically controlled Caterpillar shock absorber design absorbs shocks, ensuring a smooth ride.
Nitrogenic batteries
Nitrogen and oil batteries absorb and dampen road bumps.
Castle pillows pillows
The electronically controlled suspension is locked to provide positive control of the cutting edge during loading and unloading.
Double design kingbolt
The double king-bolt design withstands heavy external loads and makes it easy to install and remove.
Connections
The extensive use of steel castings eliminates many welded joints, making a strong hitch.
A bowl
Caterpillar Coal Scraper bowls are shipped from a plant that is specifically designed to process coal.
Auger mechanism
The screw mechanism in the bowl improves the load capacity by lifting the material from the cutting edge and transferring it to the top of the load.
Tandem power
The scraper for processing coal should work around the clock, in all weather conditions.
Taxi
A standard rubber cabin reduces noise and vibration for comfortable work during a shift.
Control
Easy control is easily accessible for precise and precise control.
Steering
Hydraulic servo-steering system provides light car feel and excellent maneuverability.
Steering column
The tilt of the steering column is adjustable in five different positions for operator comfort and control.
Seats
The suspension seat provides a comfortable ride.
Electronic monitoring system
The electronic monitoring system checks important systems of the machine and issues a three-level warning.
Radio
The operator station includes radio compatible wires in the cockpit.
Features
The standard features of the 657E cab are air conditioners, providing convenience and performance to the operator, as well as turn signals.
Fuel tank
A fuel tank mounted on the scraper improves access to the tractor`s engine compartment.
Wiring harness
The improved wiring harness includes color and numbered circuits for quick identification, fuses of at least 10 A and improved connectors.
Diagnostic connector
Diagnostic connector with a service tool allows you to quickly analyze the circuit start and charge.
Sealing rings
O-rings help keep these machines dry.
Centralized lubricants for lubricant
Centralized lubrication units for coupling and steering reduce lubrication time.
Service points
Engine service points are grouped on the right side for easy access.
Service platforms
Service platforms and multiple handrails improve access and security.
Availability of parts
Increasing the commonality of components with other Caterpillar scrapers / machines increases parts availability.
Engine disconnection
Electronic engine shutdown at ground level for convenient operator and service area operation.
Radiator
The radiator with a folded core allows you to replace individual cores in the form of modules, which reduces time and maintenance costs.
Retarder
Hydraulic retarder extends the service life of the brakes when working on heavy slopes.
Bumpers
The rounded sides reduce grip on high walls.
Casting
Extensive use of castings in the frame, sample and bowl provides a long service life.
Wiring harness and hose assemblies
Wiring harnesses and hose assemblies are lowered through the traction arms, eliminating the need for a “skipping” line, which can reduce the efficiency of the hydraulic system.
Tires
Standard tires provide maximum throughput of the available options.
Scrap drive protection
The universal joint scraper protection protects the output housing, the differential and the ejector cylinder, which helps minimize transmission maintenance costs.
Laminated thermal protection
A laminated thermal shield helps maintain the surface temperature in the engine compartment below the flash point of diesel fuel.
