Structures

The K Series™ features many of the components designed
andproven reliable over generations of product design.

Strata Precleaner

The system removes 93% of the dust particles before the
air has reached the primary engine air lter. 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 ows down the center of the tube
and continues into the primary air lter. The primary bene t
is extended  lter life.

Cold Start/High Altitude Package

A new optional cold start package includes a fan pump
bypass, transmission pump bypass, additional battery
capacity, and an engine heater plug/cord. The bypass
systems reduce the parasitic load on the engine, while the
additional battery capacity increases the cold cranking
revolutions during startup. 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.

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
exibility 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, rattle­free t. 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 t through the life of
the coupler. Tight t gives better tool control and increased
productivity. Coupler durability is substantially increased
over traditional couplers.

Fusion™ eliminates

coupler offset...

...with

substantial
improvements in
center of gravity.

Enhanced 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, enhance 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 Caterpillar 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 exibility and  eet options
not found with any other wheel loader coupler.

ForceFeedback (Speed Sensitive)

The industry leading EH joystick steering system combines
operator comfort and precision control to provide a
sustainable work environment for the operator. The system
incorporates a force feedback motor that automatically adjusts
the effort needed to tilt the ergonomic joystick based on
ground speed, resulting in superior control in all applications
and climates. For customers who prefer a steering wheel, an
electro-hydraulic steering wheel is available as an option.

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and 3V 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.

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. This contributes to a well-rested operator, who
remains efcient and productive. All Day. Every Day.

Information Display

The central display panel has a large text box,  ve analog­like 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.
The navigation buttons are located on the side of the screen
and help assist with set up and other various functions.

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 ltration 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 efcient and productive all shift long due to a
sustainable work environment.

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 removing the steering wheel,
adding a convex windshield, and eliminating two cabposts.
The cab has a clean and clear panoramic view for 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.
