Engine

Reduced emissions, economical and reliable performance

Cat® C6.6 ACERT™ Engine

The Cat C6.6 ACERT engine delivers more horsepower
usingsignicantly less fuel than the previous series engine.

Emissions Solution

Equipped to meet U.S. EPA Tier 4 Interim emission standards,
the 320E’s C6.6 ACERT engine features an aftertreatment
regeneration solution that requires no operator intervention.
Theregeneration process automatically starts once the
ltering system reaches a certain level – with no interruption
to machine performance or the work process.

Biodiesel-Ready Fuel System

The C6.6 ACERT engine is equipped with an electronic­controlled high-pressure fuel system that includes an electric
priming pump and three-layer fuel hoses to allow the use
of biodiesel (meeting ASTM 6751 or EN 14214) up to
B20(biodiesel 20% mixture).

Cooling System

The cooling system features an air-to-air aftercooler and
A/C condenser that tilt up and swing out of the way for easy
servicing; the viscous fan automatically adjusts to ambient
temperatures to help reducefuel consumption and noise.

Speed and Power Control

The 320E features speed control to maintain a constant
speed – regardless of load – to improve fuel economy.
Threedifferent power modes are offered: high power,
standard power, and economy power. The operator can
easily change between modes through the monitor or
consoleswitch to meet the needs for the job at hand –
all to help manage and conserve fuel.

3

Operator Station

Comfort and convenience to keep people productive

Seats

The seat range includes air suspension, heated, options.
Allseats include a reclining back, upper and lower seat slide
adjustments, and height and tilt angle adjustments to meet
operator needs for comfort and productivity.

Controls

The right and left joystick consoles (1) can be adjusted to
meet individual preferences, improving operator comfort and
productivity during the course of a day. With the touch of a
button, one-touch idle reduces engine speed to help save fuel;
touch it again or move the joystick and the machine returns
to normal operating level.

Monitor

The 320E is equipped with a 7" LCD (Liquid Crystal Display)
monitor (2) that’s 40% bigger than the previous model’s
with higher resolution for better visibility. In addition to an
improved keypad and added functionality, it’s programmable
to provide information in a choice of 42 languages to

1

support today’s diverse workforce.

An “Engine Shutdown Setting” accessible through the monitor
allows owners and operators to specify how long the machine
should idle before shutting down the engine, which can save
signicant amounts of fuel.

The image of the rearview camera is displayed directly on the
monitor. Up to two different camera images can be displayed
on the screen.

Power Supply

Two 12-volt power supply sockets are located near key
storage areas for charging electronic devices.

Storage

2

Storage spaces are located in the front, rear, and side consoles.
A specic space near the auxiliary power supply holds MP3
players and cell phones. The drink holder accommodates
large mugs with handles, and a shelf behind the seat stores
large lunch or toolboxes.

Automatic Climate Control

The climate control system features ve air outlets with
positive ltered ventilation, which makes working in the heat
and cold much more pleasant.

4

Hydraulics

Power to move more dirt, rock, and debris with speed and precision

Hydraulic Horsepower

Hydraulic horsepower is the actual machine power available to do work through implements and work tools. It’s much more
than just the engine power under the hood – it’s a core strength that differentiates Cat machines from other brands.

Main Control and Auxiliary Valves

The 320E uses a high-pressure hydraulic system to tackle the toughest of work in short order. A highly ef cient andsimple
back-to-back main control valve improves fuel consumption and allows for greater tool versatility.

Electric Boom Regeneration Valve

This valve minimizes pump ow when the boom lowers down, which helps improve fuel efciency. It is optimized for any
dialspeed setting being used by the operator, which results in enhanced boom lowering speed for greater controllability.

Heavy Lift

The 320E features a heavy lift mode, which increases machine system pressure to improve lift over the front of the machine –
anice benet in challenging situations. The system’s pressure increase combined with a reduction in engine speed and heavier
counterweight option give operators better control when lifting robust objects like concrete pipe and road construction barriers.

5

Structures & Undercarriage

Built to work in rugged environments

Frame

The upper frame includes reinforced mountings to support
the Roll-Over Protective Structure (ROPS) cab; the lower
frame is reinforced to increase component durability.

Undercarriage

Fixed gauge long undercarriage systemsare available
to support various work applications. Heavy-duty track
rollers, precision-forged carrier rollers, press-t pin master
joints, and enhanced track shoe bolts improve durability
and reducethe risk of machine downtime and the need
andcostto replace components. Also, a segmented two­piece guiding guard is now offered to help maintain track
alignment and improve performance inmultiple applications.

Counterweights

Three counterweight options are available: 3.55 mt (3.9ton),

4.6 mt (5.1 ton) for super long reach, and 5.4 mt (5.9 ton)
for heavy counterweight conguration. Integrated links
enable easy removal of the counterweight for maintenance
orshipping.

6

Front Linkage

Made for high stress and long service life

Booms and Sticks

The 320E is offered with a range of booms and sticks (see list below). Each is built with internal bafe plates for added
durability, and each undergoes ultrasound inspection to ensure weld quality and reliability.

Large box-section structures with thick, multi-plate fabrications, castings, and forgings are used in high-stress areas such
as the boom nose, boom foot, boom cylinder, and stick foot to improve durability.

The boom nose pin retention method is a durable captured ag design. Boom durability is improved with a number of plate
thickness changes. Also, the front linkage pins’ inner bearing surfaces are welded, and a self-lubricated bearing is used to
extendservice intervals and increase uptime.

Selections

There are three basic boom options: HD, ES, and SLR. Sticks match the boom descriptions and applications below:

• HD = Heavy Duty – This type of boom is designed to balance reach, digging force, and bucket capacity. It covers the vast

majority of applications such as digging, loading, trenching, and working with hydraulic tools.

• ES = Extreme Service – This type of boom is best used for demolition or extreme applications where stress loads on the

boom are increased. It should be used for demanding, harsh applications like 100% rock and extensive hammer use.

• SLR = Super Long Reach – This front offers reaches to over 51 feet. It is well suited for ditch cleaning applications.

7

Work Tools

Dig, hammer, rip, and cut with condence

An extensive range of Cat Work Tools for the 320E includes
buckets, compactors, contractors’ grapples, trash grapples,
scrap and demolition shears, pulverizers, hammers and thumbs.
Each is designed to optimize the versatility and performance
of your machine.

Quick Couplers

Quick couplers allow one person to change work tools in
seconds for maximum performance and exibility on a job
site. One machine can move rapidly from task to task, and
a eet of similarly equipped machines can share a common
work tool inventory.

Cat Center-Lock™ Pin Grabber Coupler

Center-Lock is the pin grabber style coupler featuring a
patented locking system. A highly visible lock clearly shows
the operator when the coupler is engaged or disengaged from
the bucket or work tool.

Buckets

Cat buckets are designed as an integral part of the 320E and
feature new geometry for better performance. The leading
edge has been pushed forward, resulting in more ef cient
lling and better operator control for greatly improved
productivity. Wear coverage in the corners and side cutter
and sidebar protector coverage are improved. All bene ts
are captured in a new bucket line with a new bucket naming
convention.

Caterpillar offers standard bucket categories for excavators.
Each category is based on intended bucket durability when
used in recommended application and material. Buckets are
available as pin-on or can be used with a quick coupler.

8

General Duty (GD)

GD buckets are for digging in low-impact, low-abrasion
material such as dirt, loam, and mixed compositions
of dirt and  ne gravel.

Heavy Duty (HD)

The most popular bucket style, HD buckets are a good
starting point when digging conditions are not well known
like a wide range of impact and abrasion conditions that
include mixed dirt, clay, and rock.

Severe Duty (SD)

SD buckets are for higher abrasion conditions such as
wellshot granite and caliche. Red area on bucket image
illustrates additional protection against wear as compared
toa GD bucket.

Specialty Buckets

In addition to the standard four bucket categories,
specialtybucket styles are available for the 320E, each
with a different purpose:

• Ditch Cleaning buckets for cleaning ditches, slope

grading, and other  nish work.

• Center-Lock Pin Grabber Performance buckets for

maximum digging performance while keeping the
versatility and convenience of a coupler.

• Wide Tip buckets for low impact material where leaving

asmoother oor and minimal spillage are necessary.

Hydraulic Kits

Caterpillar offers eld-installed hydraulic kits that are uniquely
designed to integrate Cat Work Tool attachments with Cat
Excavators. Hoses and tubes are pre-made, pre-shaped, and
pre-painted to make installation quick and easy.

Integrated Technologies

Solutions that make work easier and more efcient

Cat® Grade Control Depth and Slope

This optional system combines traditional machine control and guidance with standard factory-installed
and calibrated components, making the system ready to go to work the moment it leaves the factory.
Thesystem utilizes internal front linkage sensors – well protected from the harsh working environment –
to give operators real-time bucket tip position information through the cab monitor (1), which minimizes
the need and cost for traditional grade checking and improves job site safety. It also helps the operator
complete jobs in fewer cycles, which means less fuel use. Cat dealers can upgrade the system to full three­dimensional control by adding proven Cat AccuGrade™ positioning technologies, including GPS and
Universal Total Station (UTS).

Cat Product Link

This optional system is deeply integrated into the machine monitoring system and is designed tohelp
customers improve their overall eet management effectiveness. Events and diagnostic codes as wellas
hours, fuel consumption, idle time, machine location, and other detailed information are transmitted to
asecure web based application (2 and 3) called VisionLink™, which uses powerful tools to communicate
tousers and dealers.

10

Serviceability

Fast, easy and safe access built in

Service Doors

Wide service doors and a one-piece hood (1) provide easy
access to the engine and cooling compartments. Both doors
and hood feature enhanced hardware and a new screen
design tohelp minimize debris entry.

Compartments

The pump (2), radiator (3), and air cleaner compartments
provide ample access to major components and regular
service items like fuel and oil lters. The fresh air  lter is
located on the side of the cab to make it easy to reach and
replace as needed. Atilt-up ATAAC and swing-out A/C
condenser make cleaning cores a much easier task to perform.

Other Service Enhancements

The water separator with water level sensor has a primary
fuel lter element located in the pump compartment near
ground level.

The electric priming pump is mounted before the primary
lter base and is easy to service compared to atraditional
hand-priming pump.

The fuel tank features a remote drain cock located in the
pump compartment to make it easy to remove water and
sediment during maintenance.

The engine oil check gauge is situated in front of the engine
compartment for easy access, and a uniquely designed drain
cock helps prevent spills.

Hydraulic lash adjusters automatically adjust valve opening
and closing events to help reduce fuel consumption and
engine noise. They also eliminate the need for a valve lash,
which reduces maintenance for the customer.

*Indicates that the load is limited by hydraulic lifting capacity rather than tipping load. The above loads are in compliance with hydraulic excavator lift capacity

standard ISO 10567:2007. They do not exceed 87% of hydraulic lifting capacity or 75% of tipping load. Weight of all lifting accessories must be deducted from the
above lifting capacities. Lifting capacities are based on the machine standing on a firm, uniform supporting surface. The use of a work tool attachment point to
handle/lift objects, could affect the machine lift performance.

Caterpillar recommends using appropriate work tools to maximize the value customers receive from our products. Use of work tools, including buckets, which are
outside of Caterpillar’s recommendations or specifications for weight, dimensions, flows, pressures, etc. may result in less-than-optimal performance, including
but not limited to reductions in production, stability, reliability, and component durability. Improper use of a work tool resulting in sweeping, prying, twisting and/or
catching of heavy loads will reduce the life of the boom and stick.

Caterpillar recommends using appropriate work tools to maximize the value customers receive from our products. Use of work tools, including buckets, which are
outside of Caterpillar’s recommendations or specifications for weight, dimensions, flows, pressures, etc. may result in less-than-optimal performance, including
but not limited to reductions in production, stability, reliability, and component durability. Improper use of a work tool resulting in sweeping, prying, twisting and/or
catching of heavy loads will reduce the life of the boom and stick.
