Reliability

Tested and Proven. Ready to Work.

Structures

The K Series features many components which leverage
product designs that have delivered a reliable and durable
machine for generations.

Strata Precleaner

The system removes 93% of the dust particles before the
airhas reached the primary engine air filter. As air enters
theprecleaner, stationary vanes cause the incoming air to
spin. The resulting centrifugal force spins dust and dirt to
theouter walls where they are ejected out into the exhaust
stream, while the clean air flows down the center of the tube
and continues into the primary air filter. The primary benefit
is extended filter life.

Cold Start/High Altitude Package

A new optional cold start package includes a fan pump
bypass, transmission pump bypass, ether aid, and an engine
heater plug/cord. The bypass systems reduce the parasitic
load on the engine. With the new optional cold start package
available on K Series, starting capability has been dramatically
improved in cold weather conditions. The system also
improves starting capability at high altitudes.

Monitoring Programs

Frames

The robotically welded two-piece structural frame design
provides a rugged and reliable foundation for the machine
that improves stability, performance, and serviceability.
Arobust articulating hitch system joins the front and rear
frames improving durability. Enhanced line routings across
the hitch joint streamline the manufacturing process and
improve reliability and durability.

Engine

The new Cat C7.1 ACERT™ engine was designed to optimize
power density. It uses a combination of technologies to reduce
regulated emissions while ensuring high performance and
excellent fuel efficiency. An upgraded ADEM™ 4 electronic
control module manages the combustion process and a new
high-pressure common rail fuel system allows precise
injection timing for a clean, efficient fuel burn. The rugged
Cat Clean Emissions Module is securely rubber mounted
onits own platform above the engine and contains a
DieselOxidation Catalyst, Diesel Particulate Filter and
CatRegeneration System. Regeneration, the process by
which soot is removed from the Diesel Particulate Filter,
iscompletely automatic and does not interrupt the
machine’swork cycle.

Emissions

The 950K features a Cat C7.1 ACERT™ engine and a
CatClean Emissions Module to deliver the performance
andefficiency that customers demand, while meeting Tier 4
Interim/Stage IIIB emissions requirements. The six-cylinder
electronic engine is turbocharged and aftercooled.
ACERT™Technology is a combination of building blocks
that includes electronics, fuel systems, air management
systems and aftertreatment components. The system is
optimized based on engine size, the type of application and
the geographic location in which it will work. The technologies
are applied systematically and strategically to meet high
customer expectations for productivity, fuel efficiency,
reliability and service life.

Axles

The axles are designed to handle extreme applications
resulting in reliable performance and extended life. The front
axle is rigidly mounted to the frame in order to withstand
internal torque loads and still maintain support for the wheel
loader. The rear axle can oscillate to ±13 degrees helping to
ensure all four wheels stay on the ground providing stability
even in the roughest terrain.

Productivity

Move More. All Day. Every Day.

Z-bar Linkage

Caterpillar engineers used an innovative systems integration approach to completely redesign the linkage system to meet
customer needs in many applications. Development of the new optimized Z-bar linkage was done in conjunction with the
Performance Series Buckets, Fusion™ coupler and Fusion™ family of work tools to ensure that all components function
together to optimize visibility, performance and fuel efficiency. Visibility has been optimized by placing line routings and
structural components out of the operator’s sight lines. New parallel lift capabilities and a 30 to 60 percent increase in tilt
forceat maximum lift enhance performance and versatility.

Load Sensing Hydraulics

Load sensing hydraulics produce flow and pressure for the implement system upon demand and only in amounts necessary to
perform the needed work functions, enhancing machine productivity and fuel efficiency. Implement controllability is improved
through simultaneous implement operation and repeatable fine modulation, enabling greater operator comfort through ease
ofoperation.

Ride Control

Ride control provides the operator with a smoother ride over rough terrain, enabling a more comfortable ride at higher speeds.
The benefit is reduced cycle times higher productivity and better fuel efficiency while performing load and carry applications.
The system works by using an accumulator to dampen the linkage motion, acting as a shock absorber.

Torque Converter

The 950K torque converter has been optimized to improve fuel efficiency and deliver more power to the ground.

Transmission

The K Series transmissions incorporate a new shifting strategy that delivers smoother shifts, faster acceleration, and better
performance climbing a grade. When placing the transmission into forward gear, the machine will automatically start in second
gear. With the further enhancement of a torque based 2 to 1 downshift, the downshift will only occur based on machine load.
Owners and operators will fully benefit from utilizing the automatic 1-4 transmission mode, which results in lower fuel
consumption and optimal machine performance.

Versatility

Work Tool Options to Meet Your Needs

Work Tools for Many Job Site Requirements

An extensive range of work tools and bucket styles are
available for the 950K to customize these machines for your
operation. The list includes: Performance Series Buckets
(General Purpose, Material Handling, Rock); Specialty
Buckets (Multi-Purpose, Side Dump, High Dump, Top Clamp,
Waste Handling, Woodchip); Pallet Forks, Forestry Forks
(Log and Lumber, Logging, Millyard, Unloading Grapple),
Pipe and Pole Forks; Plows (angle or V-style); and Rakes
(withor without top clamp).

Performance Series Buckets:
Load Easy, Fuel Efficient, Carry More

Performance Series Buckets utilize a system-based approach
to balance bucket shape with the machine’s linkage, weight,
lift and tilt capacities. Operators benefit from reduced dig
times and better material retention; ultimately translating
into significant productivity and fuel efficiency improvements.

Lower Operating Costs

Performance Series Buckets feature a longer floor that easily
digs through the pile and provides excellent visibility for the
operators to see when the bucket is full. Less time digging in
the pile results in lower fuel consumption and improved tire
life. A unique spill guard protects the cab and linkage
components from material overflow.

Higher Productivity

Performance Series Buckets achieve higher fill factors –
ranging from 100% to 115% depending on the machine
application and material type. The buckets feature optimized
geometry with a bucket opening matched to the machine’s
linkage and incorporate a curved side profile to maximize
material retention. The optimized design results in unsurpassed
production capabilities.

Unloading Grapple Fork

The new Unloading Grapple Fork is ideal for unloading
andstacking timber. A rounded top clamp and frame open
the interior profile of the fork, enabling larger capacity loads
to be moved. Easy and gentle loading out of stacks is permitted
by the short tines, while a large, broad clamp holds tight to
short or long timber. Forks are available with a kick-out
thatunloads the fork even at full lift, enabling higher
lumberstacking.

Fusion™ Quick Coupler

Improved Machine Performance

Fusion™ is the patented wheel loader coupler system from Caterpillar.
The Fusion Coupler System provides performance virtually identical
to pin on – with all the flexibility of a quick coupler system. The Fusion
Coupler sits back, close-in to the loader arms – minimizing offset and
increasing the machine’s performance.

No Loss of Performance

Imagine lifting a hundred pound box with your arms fully extended.
Now imagine lifting that same load close to your body. That’s the
genius of Fusion: designed to integrate the work tool and the machine
by pulling the coupler and tool closer in to the loader. As a result, the
center of gravity is moved inward, towards the machine. This translates
to increased lifting ability when compared to machines equipped with
other coupler systems.

Unsurpassed Durability

An advanced wedging mechanism creates a tight, rattle-free fit.
Thispatented lock up system eliminates play and wear – resulting
inalong service life. Wedges pull the attachment tight to the machine
intwo directions – in and down. Constant hydraulic pressure on the
coupler wedges compensate for wear, assuring a tight fit through the
life ofthe coupler. Tight fit gives better tool control and increased
productivity. Coupler durability is substantially increased over
traditional couplers.

Increased Visibility

An open coupler frame design clears sight lines from the operator’s
seat, making it easier than ever before to engage and disengage
attachments with certainty. Offset tines and other design changes to
Fusion Pallet Forks, working in conjunction with the Fusion Coupler,
increase visibility substantially at ground level and truck bed height
when compared to traditional coupler and fork combinations.

Common Interface Compatibility

The Fusion Coupler System gives Cat customers one common interface
– eliminating the need for many different couplers across the entire
range of small and medium wheel loaders. This expanded machine
compatibility not only allows one machine to use a range of work
tools, but also allows one work tool to be picked up by machines
ofmany different sizes.

The Fusion coupler interface is designed to work on 924 through
972machines. Each machine will have its own optimal bucketand fork
recommendations. However, cross-machine compatibility gives you
additional flexibility and fleet options not found with any other wheel
loader coupler.

Operator Environment

Safe. Comfortable. Efcient.

Conventional Steering

The conventional steering configuration offers a low-effort
hand metering unit hydraulic steering system. Load sensing
steering directs power through the steering system only when
needed. The optional Command Control Steering is still
offered on the 950K and is a load sensing system that links
the steering wheel and frame angle positions to provide the
proper amount of steering control. Full machine articulation
is accomplished with a ± 70 degrees turn of the wheel versus
two or three 360 degree turns on a conventional steering wheel.

Implement Controls (EH)

Seat mounted single axis implement control levers provide
the operator with precise control of the work tool, all
whilemoving with the seat for maximum comfort. In cab
programmable kick-outs and automatic cylinder snubbing
maximize operator comfort and productivity throughout
their shift. Optional implement joysticks are available for
2V,3V, and 4V hydraulics.

Seat

The Cat Optimized Seating System is 6-way adjustable to
accommodate operators of all sizes. The seat has a one piece
high back that supports the lumbar area of the back up through
the shoulders. Both armrests are large and can be adjusted
up, down, fore, and aft to enhance comfort and convenience.
An optional feature for the cab seat is a heated backrest
andcushion.

Automatic Climate Control and Air Quality

The new climate control system automatically adjusts the air
temperature and fan speed to maintain the operator’s preferred
climate setting. The cab air filtration system recirculates
90%of the cab air and is now serviced from outside the cab,
enabling maximum air quality and cab cleanliness. The new
air conditioning sealing system keeps refrigerant contained
preventing system shutdown. Combined together, the operator
remains efficient and productive all shift long due to a
sustainable work environment.

Information Display

The central display panel has a large text box, five analog
like gauges, and LED warning indicators. The large text box
provides in-language information about machine operation,
feature activation and system troubleshooting and calibration.
With the 5 large analog-type gauges the operator can easily
identify if key systems are within normal operating range.
Aresettable trip totals function has been incorporated to
display information for average fuel consumed, total fuel
consumed, idle fuel, idle time, operating hours, odometer, etc.

8

Entry and Exit

Well-placed grab bars and a ladder inclination angle of
10-degrees forward makes the walk into the cab feel more like
a staircase than a ladder. The new wider front hinged door can
be opened and closed while seated, greatly improving ingress
and egress. Two new left-hand and right-hand sliding windows
can also be opened and closed with one hand while seated for
comfortable communication to personnel on the ground.

Visibility

Visibility has been enhanced by adding a convex windshield
and eliminating two cab posts. The cab has a clean and clear
panoramic view to enhance safe operation of the machine.
External rearview mirrors are mounted on the cab to provide
all around visibility. The external mirrors fold horizontally to
provide fast, safe access to clean the window from the front
platform. Optional heated and powered mirrors are available
to further improve visibility in cold climates.

Rearview Camera

With the new standard rearview camera, visibility is greatly
enhanced. The camera is located in a pocket on the grill to
protect it from damage and the elements. The camera can
beset to activate only when the transmission is in reverse to
help eliminate distractions in the cab, especially when in dark
environments. Two rear work lights are located in the rear
grill and can be activated to illuminate the area behind the
machine in low light conditions.

Control Panels and Park Brake Switch

Two control panels located on the front right ROPS post
consist of large membrane switches making them easy to
activate while wearing gloves. The membrane switches contain
LED’s to denote activation/mode and have a positive feel and
“click” to signal activation. The ISO symbols located on each
membrane switch are molded all the way through to ensure
the image will not wear off over time. A new “help” feature
explains the function of each membrane switch. A two position
rocker switch activates the electro-hydraulic park brake and
is automatically applied upon machine shutdown.

Sound and Vibration

New viscous cab mounts connect the cab to the frame of
themachine, decreasing noise and vibration the operator
issubjected to. The result is a sustainable work environment
and well-rested operator, remaining efficient and productive.
All Day. Every Day.

Serviceability

Easy to Maintain. Easy to Service.

Electrical Service Center

The electrical service center provides grouped ground level
access to numerous electrical features, enhancing safety
andconvenience for operators and service technicians. It is
conveniently located beneath the left platform for access
before entering the cab and contains the maintenance free
batteries, a fuse relay panel, main disconnect switch, ground
level engine shutdown switch, hood tilt switch, and the jump
start receptacle.

Engine Access

The K Series retains the Cat sloped “one-piece” tilting hood,
which has become one of our brand’s hallmarks and
provides industry-leading access to the engine, Cat Clean
Emissions Module (CEM) and other components but with
fresh new styling clearly distinct from the H Series. New to
the loaders is a rear clamshell hood design that allows quick
access to the engine oil dipstick and fill, fuel fill port, and
cooler cores.

Cooling System

The cooling system is readily accessible for clean out and
maintenance. With six cooling fins per inch and a perforated
grill, most airborne debris entering the system passes through
the cooler cores. The cooler cores swing out providing easy
access for cleaning; an option variable pitch fan is available
to automatically purge the cooler cores by periodically
reversing the airflow.

Hydraulic Service Center

The hydraulic components are all conveniently located
behind the hinged right side access ladder at a new single
ground level service center improving safety and reducing
service time. Accessible from the service center are the
transmission and hydraulic oil filters, brake accumulators,
pressure test ports, etc.
