657G Features
Economical Hauling System
The wheel tractor-scraper, with its ability to load
quickly, haul at high speeds and dump on the go,
has the potential to be the most profitable hauling
system on the job site. This efficiency can result
in fewer machines on the job, reduced operating
costs and jobs delivered in a shorter period of time.
Power Train
Cat designed and manufactured power train
components deliver the power necessary for
fast loading and quick hauls. Dual power ratings
increase component life in gears 1-2 and deliver
maximum productivity in gears 3-8.
Operator Station
Single joystick control of implements, adjustable
arm rests, seat, steering column and room to
maneuver all reduce fatigue and increase operator
comfort and productivity throughout the shift.
Cushion Hitch
Cushion hitch is a Caterpillar proven system for
improving ride quality, dampening loads that might
otherwise be carried through the frame to the
operator. Cushion hitch offers operators a more
comfortable haul portion of the work cycle.
Durability
Cat 657G wheel tractor-scrapers have a history
of robust structural design, tested and validated
to last in the most rugged loading and hauling
conditions.

5
Electronic Controls
Optimized machine performance and advanced diagnostic capabilities
Benefits of Electronic Control Modules (ECMs)
ECMs (3 on the tractor, 2 on rear-powered scrapers) offer:
•
Better fuel economy by optimizing engine settings
•
Greater reliability with operator warnings if problems arise
•
Combining tractor and rear powered-scraper monitoring
systems, easy access diagnostics, more durable
components improves serviceability
•
Reduced exhaust smoke by optimizing the fuel/air ratio
during cranking, starting and acceleration
•
Air filter restriction indicator alerts operator if filter
exceeds allowable limit
•
Periodically raises engine rpm during low idle to keep
the batteries fully charged
Combined Electronic Monitoring System (EMS III)
Monitors both the tractor and scraper status on the 657G;
access fault codes from one location. The tractor and powered
scraper use the same controller for parts commonality and
easier servicing.
Product Link Ready
This wireless system lets the customer track location, service
meter hours and machine health information. Can also issue
alerts if the machine is operated beyond owner defined time
and location limits.
Easy Access Diagnostics Means Faster Problem Solving
Diagnostic codes, via the Electronic Technician (Cat ET),
and a radio call can often let the service technician know which
tools, manuals, and possibly even replacement parts to bring.
6
Structures
Superior design and construction delivers long term durability
Cushion Hitch
The electronically actuated cushion hitch has a parallelogram-type linkage for exceptional strength.
Vertically mounted hydraulic cylinder transfers road shocks to nitrogen accumulators. Nitrogen accumulator
absorbs and dampens road shocks, thus preventing these loads from being transmitted to the operator.
•
controlled oil flow dampens rebound oscillation
•
leveling valve applies pressure via an orifice to automatically center piston in the load cylinder
•
steel castings are used to eliminate many welded joints and increase strength
•
double-kingbolt design withstands high external forces and simplifies installation and removal
Lockout Switch
An operator-selectable lockout switch, located on the joystick, locks the cushion hitch down for improved
cutting edge control when loading or dumping.
7
Scraper Bowl
Designed for fast and precise loading and controlled ejection
Bowl Design
Excellent productivity, improved draft arm protection, and
better load retention. Low profile design offers less resistance
to incoming materials, while cellular construction adds strength
and dent resistance to bowl sides and floor.
Bulldozer Ejection System
Combines constant spreading control with minimum carryback.
Overflow Guard
An available overflow guard on the scraper bowl helps retain
material, and limits spills onto the rear of the scraper.
Push-Loading
Where material types include rocky/abrasive material, or
become traction-limited, push loading a 657G with a Cat D10
or D11 will optimize tire wear and productivity.
Cutting Edges and Cat Ground Engaging Tools (GET)
May be adjusted according to job conditions. Smooth and
serrated cutting edges with available tip options can be applied
to match job site conditions. For most efficient loading, use
the thinnest cutting edge that provides satisfactory wear life
and impact resistance.
Tandem Engines
Tandem engine machines improve cycle times on grades and
in slippery underfoot conditions. Also improves the machine’s
loading characteristics in tough materials like clay.
Material Appetite
Well suited to handle a wide variety of material from clay
to shot rock.
8
Coal Bowl
Purpose-built to meet application specific needs
Bowl Capacity
High-capacity bowls, built longer and taller than earth-moving bowls, allow the 657G to achieve rated
load in light weight coal.
Wheel Tractor-Scraper Benefits
•
High speed, self-loading productivity for stockpile and feeder management
•
Coal pile compaction
•
Bowl capacity 56 m³ (73 yd³) heaped
•
All-wheel drive allows the machine to work in poor underfoot conditions and operate on piles
of loose coal
9
Push-Pull
Two machines acting as a single self-loading system
Combined Power Increases Production
Push-pull applies the power of four engines to a single
cutting edge. The benefit is realized in tough-to-load material
and fast loading of both machines. Push-pull applications
have the potential to produce the lowest cost per unit volume,
and a high rate of production.
Hydraulically Actuated Bail
The push-pull arrangement uses a hydraulically actuated bail
and cushioned plate to push, and a hook that is attached to
the rear of the scraper to pull.
10
Serviceability
Easy to Maintain – Easy to Service
Engine Service Points
•
Maintenance/service points grouped on the right side
•
Grouping fluid fill and check points, filters and sampling ports shortens maintenance times
•
Electronic Monitoring System (EMS) provides real-time information to the operator of system warnings
•
Electronic Technician (Cat ET) displays real-time system data to better inform the service technician
Implement Valve Relocation
The implement valve is relocated from the tractor to the top of the scraper draft tube, reducing the number of
hoses and tubes crossing over the gooseneck. This reduces potential leak points and improves service access.
Scraper Electrical Harness and One Piece Power Block
The flexible ribbon wiring harness oscillates with the machine, and polyurethane boots offer better protection
against the elements. The jumpstart receptacle and disconnect switch are integrated into a one-piece power
block, with a lockable cover, for better electrical integrity and serviceability.
Electro-Hydraulic Implement Control Simplifies Serviceability
Removing the cab pilot valve and associated lines improves reliability and reduces noise. The high efficiency
electro-hydraulic pilot oil filter provides cleaner oil for the pilot system.

Gradeability/Speed/Rimpull
Retarding
To determine gradeability performance: Read from gross weight
down to the percent of total resistance. Total resistance equals
actual percent grade plus 1% for each 9 kg/t (20 lb/ton) of rolling
resistance. From this weight-resistance point, read horizontally to
the curve with the highest obtainable gear, then down to maximum
speed. Usable rimpull will depend upon traction available and
weight on drive wheels.
To determine retarding performance: Read from gross weight down
to the percent effective grade. (Effective grade equals actual percent
grade minus 1% for each 9 kg/t (20 lb/ton) of rolling resistance).
From this weight-effective grade point, read horizontally to the
curve with the highest obtainable speed range, then down to
maximum descent speed the retarder can properly handle.
