MACHINE LIFE. The 993K is designed
to meet customer rebuild requirements
and a high hour structure life. This is
accomplished through design emphasis
put on key components:

Caterpillar Designed Components.

Components used to build Cat Wheel
Loaders are designed and manufactured
to Caterpillar quality standards to
ensure maximum performance even
in extreme operating conditions.

• Linkage. The 993K features the field
proven Z-bar linkage design with new
maintenance-free sleeve bearing (SB)
pins. A key benefit of the SB pins is
when maintenance is required, customers
can schedule change out of pins on a
planned maintenance day. Design of the
SB pins allows this planned downtime
due to the fact it has low risk of
consequential damage. In addition,
significant growth in width for support
of the Z-bar linkage further increases
strength and durability.

• Cat Planetary Power Shift
Transmission. The 993K has increased

strength and reliability by utilizing a
similar planetary gear group used in
the Cat 994F.

• Front and Rear Frames. The front and
rear frames are spread further apart
for improved bearing life. A key
differentiator from competitive machines
is the box section rear frame and four
plate loader tower. The box section
absorbs torsional forces generated in a
loading cycle, maintaining alignment
for hitch pins and drive line. The four­plate loader tower resists shock and
torsional loads maintaining hitch and
loader linkage pin alignment.

• Axle Shaft Service Brake. Sharing
similar components with the Cat D9R,
this service brake provides improved
retarding capabilities and better braking
ability. Positive oil flow and brake oil
cooling result in improved brake disc
durability. Additionally, the 993K
third gear run out stopping distance
is greatly reduced.

4

Reliability, durability, uptime of the machine – it’s what you expect for your bottom line.

Reliability/Durability

• Next Generation Modular Radiator
(NGMR). Utilizing 14 parallel flow

system modular cores, the NGMR
increases cooling performance by only
drawing cooler ambient air through the
radiator system.

PROVEN ENGINE TECHNOLOGY.

The 993K utilizes the Cat

®

C32 engine
which fully meets U.S. EPA Tier 2/EU
Stage II emissions requirements.
This Mechanically Actuated Electronically
Controlled Unit Injection (MEUI) diesel
engine shares a common platform with
the Cat 777F, 854K, 992K and Dll.

DIAGNOSTIC PROGRAMS.

Monitoring product health is key to
maintaining reliability of any equipment.
Many programs are available on the 993K,
both as standard and optional features,
to help you track machine condition.

VIMS Monitoring System with Enhanced
Display. Monitoring over 100 machine

parameters, VIMS records these
parameters for maintaining and optimizing
the machine. VIMS features System
Events and Data Events, giving
notification from machine malfunction
to changes in pre-programmed
machine settings.

Product Link. Product Link is a state­of-the-art satellite technology based
product that provides an information
flow between machine on-board systems
and the Caterpillar operations center.
Multiple types of information can be
collected and tracked – from machine
location and service meter hours to
health and productivity information.

Equipment Manager. With a subscription
to Equipment Manager through the
Cat Dealer StoreFront, the information
collected through Product Link can be
transmitted to a computer. With fast,
easy-to-access machine information,
you can optimize asset utilization, reduce
security risks, improve maintenance
management and implement before­failure repair strategies.

• Move more tons of material with
the increased productivity of this
25 ton loader

• Improved system design gives the
993K optimum productivity

• Pass match the 993K with the right
truck for improved job site efficiencies

MOVE MORE TONS. Lower your cost
per ton by delivering maximum
payload. This 25 ton rated loader can
help your bottom line with increased
productivity. This is accomplished
through additional power, improved
cycle time and continuously high
bucket fill factors on every dig cycle.

OPTIMUM PRODUCTIVITY. The 993K
has designed a number of key systems
and features to achieve the maximum
power for a machine of this size class.
Increased breakout force, more rimpull
coupled with fill factor and increased
power gives the 993K optimum
productivity.

Positive Flow Control (PFC). PFC
ensures faster hydraulic implement
response, giving the operator improved
feel and control of the bucket. With PFC,
customers see a decrease in cycle time.

Impeller Clutch Torque Converter
(ICTC)/Rimpull Control System.

Mixing new with a current validated
system, customers can maintain hydraulic
balance while digging and loading by
utilizing the ICTC/Rimpull Control
System. The ICTC enables the operator
to finely modulate rimpull for smooth
machine operation.

Steering System. Load sensing steering
reduces the demand on the hydraulic
system when steering is not activated.
By delivering only the power draw that
is needed, engine power is reserved for
productive work.

Double Reduction Final Drives.

The 993K final drives are built off the
D11 design platform and tailored for
wheel loader applications. The double
reduction final drives enable the increase
in rimpull. Additional benefits include
significantly reducing power train stresses
resulting in longer overall power train
life, durability and ease of service.

Linkage Pins. The 993K features durable,
service-free,oil filled and sealed-for-life
Cat Sleeve Bearing (SB) pins. The SB
pins eliminate the need for daily greasing
of the front linkage and requires no
routine maintenance for continued uptime.

with F/N/R rocker switch and
upshift/downshift switches.

• Transmission clutch control for
improved shift quality, component
life and operator comfort.

• ICTC for improved rimpull control
and transmission clutch durability.

Truck Pass Match. It is not always
about working harder, but working
smarter – optimize the wheel loader
to the trucks. This is accomplished
through even passes when loading and
optimizing operation for efficiencies.
The 993K was developed to optimize
pass match with key trucks in this size
class and job site requirements.

• Good visibility for a safe work
environment

• Get your operator safely on and off
the 993K

• Daily and routine maintenance
features allow your service technician
to safely service the machine

IMPROVED VISIBILITY. Good visibility,
whether it is an operator needing front
viewing for positioning to a truck or
side viewing for vehicles or people in
the work area, is key to a safe work
environment. With a 14 percent increase
in cab space and a .6 m (2 ft) increase
in cab height, the operator has one of
the best viewing capabilities in the
industry for this wheel loader class size.
Additional standard visibility features
that enhance safety include:

In-Cab Monitor. An optional rear vision

camera with 178 mm (7 in), in-cab, color
display monitor is available to give a
close view of behind the wheel loader.

Working 24 Hours a Day. Any time
of the day and in all types of weather,
the 993K has a number of features
to ensure safe visibility. Rear heated
mirrors are available for quick defrost
and good visibility in winter conditions.
The optional High Intensity Discharge
(HID) lights provide exceptional lighting
for night work. Rotating warning beacons
are also available as a safety feature.

ACCESS and EGRESS. Getting on and
off the machine is one of the leading
causes of injury on a jobsite. The new
993K has several standard and optional
features that help to ensure your operators
get safely on and off the machine.

Wider Platform Access Stairs. Both left
and right stairways are standard and
have increased in width to provide
additional room, 600 mm (23.6 in),
for operators and service technicians to
access the cab and to perform platform
maintenance procedures. Optional
roading fenders are available to prevent
mud and debris build up on the steps
and rails.

8

People are the backbone of your business and keeping them safe and productive is the
number one priority. At Caterpillar, we have designed the 993K with your most important
asset in mind.

Safety

Rear Access Egress System (RAES)
Attachment. An optional manlift

replaces the left hand ladder and lifts or
lowers the operator or service technician,
personal belongings and tools safely on
and off the platform.

MAINTENANCE SAFETY. Daily and
routine maintenance should not pose a
safety hazard to your operator or service
technician. With the 993K, design effort
was taken to group service points with
convenient access. With the standard
service or optional deluxe service center,
technicians can plan daily maintenance
by checking fluid levels and machine
parameters. This allows the technician
to prep for required maintenance and
take all material on the bumper platform
at one time rather than make trips on
and off the machine to get required
maintenance components or fluids.

Bumper Service Center. Another key
safety service point is the Bumper
Service Center. A centralized service
center located at ground level on the left
hand, rear side of the 993K includes a
lockable battery disconnect (1), auxiliary
jump start receptacle (2), stairway light
switch (3) and engine shutdown switch
(4). This center also contains lockout
switches allowing your service technician
to perform routine maintenance while
ensuring the machine stays static.

Starter Lockout Switch (5). Key to
safety, another feature on the bumper
service center is a starter lockout that
stops the ability to start the machine,
which is often needed during service
procedures. The machine will still have
electrical power, however, the engine
cannot be started.

Transmission Lockout Switch (6).

The transmission lockout switch does
not allow the transmission to shift out
of neutral, even if running. This feature
is designed for service procedures that
requires machines to be running but
need the transmission disabled for
added safety.

SAFETY IN OPERATOR ENVIRONMENT.

The operator and safety go hand-in-hand.
Many features that enhance operator
comfort also aid in keeping your operator
safe from lowering noise levels to
design features that lower vibration and
repetitive motion. Key standard features
that aid operator safety include low
effort implement controls integrated
with the seat for ease of adjustment by
the operator, front windshield cleaning
platform with handrails and a seat belted
trainer’s seat for convenient operator
training on the job site. Additional safety
features include a cab filtration system
that removes dust and debris from the
cab air. Optional for dusty applications
is a cab pre-cleaner that reduces the
amount of dust prior to reaching the
cab filter.

when you purchase your equipment.
Your dealer will help you choose a plan
that will cover everything from machine
and work tools selection to replacement
so you get the best return on your
investment.

Selection. Make detailed comparisons
of the machines you are considering
before you buy. How long do components
last? What is the cost of preventive
maintenance? What is the cost of lost
production? Your Cat dealer can give
you precise answers to these questions.

Purchase. Look past initial price.
Consider the financing options available
as well as day-to-day operating costs.
This is also the time to look at dealer
services that can be included in the cost
of the machine to yield lower equipment
owning and operating costs over the
long run.

Operation. Improving operating
techniques can boost your profits.
Your Cat dealer has training videos,
literature and other ideas to help you
increase production.

Product Support. You will find nearly
all parts at our dealer parts counter.
Cat dealers utilize a world-wide computer
network to find in-stock parts to minimize
machine downtime. You can save money
with remanufactured parts and get the
same warranty and reliability as new
products but with a 40 to 70 percent
cost savings.
