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.
In fact, hydraulic horsepower for the 336E increased from
the previous series’ output due to pump and other system
improvements. This translates into the new ESeries moving
more material in less time.

Main Control Valve and Auxiliary Valves

The 336E uses a high-pressure system to tackle the toughest
of work in short order. A new one-piece, cast-block, back­to-back main control valve features resized and reshaped oil
passages to improve efciency and serviceability; stackable
auxiliary valve attachments mount on top of the main
valve, which allows for auxiliary hydraulic lines and valve
congurations to be simplied for greater reliability.

Return Filter

The return lter is a capsule-type design with a cartridge
inside. Unlike many competitors’ offerings, the Cat cartridge
features a handle to help remove and change without oil
spillage or contamination. A sensor attached to the  lter warns
the operator if it is full or exceeds a certain pressure level.

Swing Priority Circuit

The swing priority circuit on the 336E uses a new electric
valve that’s operated by the machine’s improved Electronic
Control Module (ECM). Compared to using a hydraulic
valve, an electric valve allows for more nely tuned control,
which is critical during material loading.

Electric Boom Regeneration Valve

A new electric boom regeneration valve minimizes pump  ow
when the boom lowers down, which improves fuel economy.
It is optimized for any dial speed setting being used by the
operator, which in turn aids controllability and enhances
component durability.

Stick Regeneration Circuit

The 336E regenerates the ow of oil from the rod end of
thestick cylinder to the head end of the stick cylinder during
low-load, stick-in operation – an approach that saves energy
and expense.

Operator Station

Comfort and convenience to keep people productive

Seats

A new seat range includes mechanical, air suspension,
heated, and air cooled options. Each option includes 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 can be adjusted to meet
the operator’s desired preference, making him (or her) more
comfortable and productive during the course of a day.

With the touch of the 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.

The optional heavy lift mode increases machine system
pressure to improve lift – a nice benet in certain situations.
Heavy lift mode also reduces engine speed and pump  ow in
order to improve controllability.

Monitor

The 336E is equipped with a new LCD (Liquid Crystal
Display) monitor 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 is programmable
to provide information in a choice of 42languages to support
today’s diverse workforce.

A new “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.

In addition, the monitor serves as a display for the optional
rearview camera. Upto two different camera images can be
displayed on the screen.

MP3-Ready Radio and Power Supply

The standard radio is equipped with a new auxiliary audio
port for MP3 players. Two 12-volt power supply sockets are
located near key storage areas for charging.

Storage

Storage spaces are located in the front, rear, and side consoles.
New space near the auxiliary power supply holds MP3 players
and cell phones. The drink holder accommodates large mugs
with handles, and a new 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.

Engine

Reduced emissions, economical and reliable performance

Cat® C9.3 ACERT™ Engine

The C9.3 ACERT engine delivers more horsepower using less fuel than the previous series engine.

Emissions Solution

The C9.3 ACERT engine is equipped to meet current U.S. Tier 4 Interim regulations. Driven by customer input, Caterpillar’s
aftertreatment regeneration solution ensures the machine works as normal with no operator intervention needed.

The machine comes with two programmable modes of operation: automatic and manual regeneration.

In automatic mode, the machine starts the regeneration process once the ltering system reaches a certain level and conditions
are optimal. The system will not interrupt the work process and can regenerate during machine operation.

Manual mode enables the operator to override the automatic mode. With a touch of a button (1) inside the cab, this mode
allows the operator to move the machine from ammable or heat-restricted areas before initiating the regeneration process.

Bio Diesel-Ready Fuel System

The C9.3 ACERT engine is equipped with a high-pressure common rail fuel system that includes a new electric priming pump
and three-layer fuel hose to allow the use of bio fuel up to B20 (bio fuel 20% mixture).

Cooling System

The high-ambient cooling system features a xed-speed fan and a side-by-side-mounted radiator and oil and air coolers
foreasycleaning.

Speed and Power Control

The new E Series features isochronous 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.

Structures and Undercarriage

Built to work in rugged environments

Frame

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

Undercarriage

Standard and 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.

A new segmented three-piece guiding guard is now offered to maintain track alignment and improve
performance in multiple applications.

A redesigned motor housing prevents mudpacking and debris buildup around seals.

Counterweights

Two counterweight options are available: 6.0 mt (6.6 t) and 7.0 mt (7.7 t). Eachis designed to match
theheight ofthe machine.

Regardless of choice, counterweights are bolted directly to the main frame using four M36 bolts
forrigidity and feature an integrated housing for the new rearview camera option.

Front Linkage

Made for high stress and long service life

Booms and Sticks

The 336E is offered with a range of booms and sticks.
Eachis built with internal bafe plates and stress-relieved
foradded durability, and each undergoes ultrasound inspection
to ensure 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. Also, the
boom nose pin retention method is a captured ag design for
enhanced durability.

Selections

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

HD = Heavy Duty. This type of boom is best used for reach

applications where conditions are optimal such as excavating
basements, trenching for utility lines, and sewer applications.
The combination of boom and stick is matched to the
digging conditions.

ES = Extreme Service. This type of boom is best used

for demolition applications or extreme applications where
stress loads on the boom are increased. It should be used
for demanding, harsh applications such as 100% rock and
extensive hammer use.

ME = Mass Excavation. This type of boom is best used

forquarry and other demanding applications. Used for
high-volume production and loading, the ME front provides
higher digging forces due to the geometry of the boom and
stick. Bucket linkage and cylinders are more durable for
excellent productivity in harsh applications.

Work Tools

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

Work Tools

An extensive range of Cat Work Tools for the 336E includes
buckets, compactors, grapples, multi-processors, thumbs,
rakes, rippers, and shears. Each is designed to optimize the
versatility and performance of your machine.

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 of coupler and features
a patent-pending locking system. A highly visible secondary
lock clearly shows the operator when the coupler is engaged
or disengaged from the bucket or work tool.

Hydraulic Kits

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

8

Buckets

Cat buckets are designed as an integral part of the 336E
system 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; a new lift eye design accepts
a wide range of shackle sizes.

All benets are captured in a new bucket line with a new
bucket naming convention. Following are the types offered:

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 good for use
in a wide range of impact and abrasion conditions including
mixed dirt, clay and rock. They are a good starting point
when digging conditions are not well known.

Severe Duty (SD)

SD buckets are for higher abrasion conditions such as well
shot granite and caliche.

conditions, including high quartzite granite.

Specialty Buckets

In addition to the four levels of bucket durability categories,
several specialty buckets are available for the 336E – each
with a different purpose:

• Ditch cleaning for cleaning ditches, slope grading,

andother  nish work

• Center-Lock Pin Grabber Performance for maximum

digging performance while keeping the versatility
andconvenience of a coupler

• Power for use in abrasive applications where breakout

force and cycle times are critical

• Wide tip for low-impact material whereleaving a

smoother oor and minimal spillage arenecessary

Integrated Technologies

Solutions that make work easier and more efcient

Electric Boom and Stick Regeneration Valve

The 336E features unique electric boom and stick regeneration valves. The valves use gravity during
typical “boom down” or “stick in” operations to regenerate ow of oil from the head end of the cylinder
to the rod end of the cylinder instead of sending it all the way back to the hydraulic tank. This distinct
Caterpillar solution increases efciency and reduces cycle times and pressure loss for higher productivity
and lower fuel costs.

Cat® Grade Control Depth and Slope

This optional system (1) combines traditional machine control and guidance with standard factory­installed 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, 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 three-dimensional
control by adding proven Cat AccuGrade™ positioning technologies, including GPS and Universal
Total Station (UTS).

Cat Product Link*

This deeply integrated machine monitoring system 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 called
VisionLink™, which uses powerful tools to communicate to users and dealers.

*Product Link licensing is not available in all areas. Please consult your Cat dealer for availability.
