Oil-Cooled Pistons and Full-Length,
Water-Cooled Cylinder Liners.
Provide maximum heat transfer
for longer component life.
Engine Oil Cooler. Maintains optimum
oil temperature for proper cooling and
lubrication. Engine cooling is provided
by the Next Generation Modular Radiator.
Hydrostatic fan drive gives the standard
cooling package 110° F ambient capability.
Impeller Clutch Torque Converter (ICTC).
The converter allows the operator
maximum flexibility in modulating
rimpull. The first inch of travel of the
left brake pedal is used to modulate
rimpull from 100 percent (pedal at rest
position) to 20 percent of maximum
(pedal depressed about 25 mm [1 in]).
Once 20 percent of maximum rimpull is
achieved, the brake is applied. This gives
smooth transitions from brake-on to
brake-off, yielding fast, fluid loading
cycles. The torque converter also has
a standard lock-up clutch for fast, fuel
efficient load and carry cycles.
• The Rimpull Control System has
four factory preset reduced rimpull
settings. Each setting corresponds
to a maximum allowable impeller
clutch pressure.
• Rimpull Control System allows the
operator to vary rimpull based on
operating conditions for maximum
productivity while reducing tire
slippage and resulting costs.
• Converter de-clutches during
directional shifts. This allows
full throttle directional shifts
maintaining hydraulic speeds.
• Smooth approach to trucks and
hoppers builds operator confidence,
producing faster cycle times.
• Lock-up feature provides “direct
drive” for load and carry applications.
No converter slip means higher
efficiency and lower fuel costs.
• Improved calibration procedure.
• Left pedal modulation.
• Compensates for wear.
• Provides the ability to recalibrate
for optimum left pedal modulation
regardless of torque converter wear.

Page 5
1 Impeller Clutch. Modulates the amount
of engine power sent to the wheels.
2 Lock-Up Clutch. Provides direct drive for
improved fuel economy. With Electronic
Clutch Pressure Control, the impeller
clutch torque converter with lock-up
feature activates in second and third
gears forward and first through third
gears in reverse.
Planetary, Electronic, Power Shift
Transmission. This is the same
transmission found in the Cat 992G
Wheel Loader. Electronic shifting
provides smooth consistent shifts with
fingertip controls housed in the STIC
controller. Large diameter perimeter
clutches coupled with high contact
planetary gear sets provide high torque
carrying capacity for long trouble-free
life. Speed and direction controls are
housed in the STIC controller.
Final Drives. Are planetary consisting of a
ring gear, three planet gears or planet gear
carrier and a sun gear. Features include:
• Ring gears splined to reation hub
• Proprietary gear cutting and heat
treat methods are used in
manufacture of components
• Full-floating bronze sleeve bearings
are used on planet gears
• Oil-bath lubrication of final drive
Axle-Shaft, Oil-Disc Brakes. Are fully
hydraulic, completely sealed and never
need adjustment. Disc face grooves
provide cooling even when brakes are
applied for a long, fade resistant life.
• This design provides a larger cooling
oil reservoir and thicker separator
plates than conventional brake designs.
This gives the brake higher heat
dissipation rates giving it higher
capacity than conventional
oil-disc brakes.
• The location of the brake reduces
service time. Conventional brakes
require final drive disassembly.
The axle-shaft brake design allows
brake service while leaving the final
drive intact. Duo-cone
®
seals are
between the wheel and spindle for
a tight fit. Reduced service time (oil
change interval is every 2,000 hours)
and machine downtime keeps
operating costs low.
Parking Brake. Is spring-applied, oilreleased, dry disc that are mounted on
the transmission transfer gear output shaft.
The Electronic Monitoring System alerts
the operator if the transmission is engaged
while the parking brake is applied and
also if the pressure drops and, in which
case, the brake is automatically applied.
Manual override is possible to allow
movement of the machine.
Secondary Brakes. Are fully modulated
and the front and rear service brake
circuits are isolated, allowing one circuit
to operate if pressure drops in the other.
Service Brakes. Are four wheel,
hydraulic, oil dipped, multiple disc brakes
that are adjustment-free, completely
enclosed and allow modulated
engagement without slack adjusters.
Starting System. Is direct-electric 24-volt
with a 95-amp alternator and two 12-volt,
1,300 CCA, 190-amp-hour batteries.

Next Generation Modular Radiator
(NGMR) with Air-to-Air Aftercooling
System (ATAAC). In order to meet U.S.
EPA Tier 3 and EU Stage IIIa emissions
requirements. The cooling system has
been upgraded to a NGMR that utilizes
the ATAAC system to achieve lower
particulate, NOxand sound output.
The proven NGMR system is currently
used on other Cat models such as the
834H, 844H, 988H and 992G. ATAAC
technology became effective with the
834G and 988G.
NGMR is a Caterpillar
®
technology that
improves serviceability and increases
cooling efficiency by 22 percent.
Ambient working temperature for
the standard 990H is 43° Celsius
(110° Fahrenheit). A high ambient
cooling package, with a 50° Celsius
(122° Fahrenheit) capacity, is available
as an attachment.
ATAAC System. Provides a separate
cooling system for the intake manifold
air complementing the engine jacket water
cooling system. The ATAAC system
routes hot compressed air from the turbo
and cools it with a single pass, air-to-air
aluminum heat exchanger. The cooled
compressed air is then delivered to the
engine intake manifold. Providing the
engine with cool compressed air greatly
reduces the emissions produced, meeting
Tier 3 requirements for a cleaner
environment.
Separated Cooling System. The C27
engine with MEUI has a separated cooling
system which isolates the NGMR and
demand fan from the engine compartment.
The cooling system is isolated from the
engine compartment by a shield allowing
the radiator to receive outside ambient air
through the side and top vents at a much
lower temperature than the hot air from
the engine compartment. This improves
the system’s efficiency and allows the
radiator size to be decreased and the rear
hood to be sloped, improving the rear
viewing area. Also, sound levels are
reduced due to the lower fan speed
of a more efficient cooling system.
Serviceability. Is a key feature of NGMR.
Tubes are welded to a large, thick header,
providing the strength of the tube-toheader joint that reduces the possibility
of coolant leaks. The NGMR modular
core design allows removal of a single
core without removing the entire radiator
– reducing downtime through ease of
serviceability. Replacing the individual
core also reduces repair costs.
Two-Pass System. Is a NGMR feature for
increased cooling capacity. Coolant travels
from the engine to the fan side of the
bottom tank, up the fan side of each core,
over the top, down the engine side of the
core, into the engine side of the bottom
tank and back to the engine. The improved
flow pattern allows the coolant to pass
through the radiator twice for better
cooling. The NGMR design improves
serviceability, reduces downtime and
increases cooling capability.

Cooling System
Works with the engine to meet emissions standards as well as improve serviceability
and reduce downtime.
Page 7
Structure Construction. Is more
than 80 percent robotically welded.
This provides highly consistent welds
with deep plate penetration and excellent
plate fusion. The benefit is greater fatigue
strength and longer life than with
conventional welding methods.
1 Box Section Rear Frame. Absorbs
torsional forces generated in a loading
cycle, maintaining alignment for hitch
pins and driveline.
2 Four-Plate Loader Tower. Resists shock
and torsional loads maintaining hitch

serviceable grease B-pin and centerpoint frame articulation.
4 Computer-Controlled Machining.
At the top level allows structures to remain
in their fixture throughout the machining
process to ensure pin bore, axle pad and
engine/transmission alignments.
Optional High Lift Linkage Configuration.
Is available as a standard attachment.
The High Lift configuration offers
565 mm (22.3 in) more dump clearance
and 293 mm (11.5 in) additional reach
at full lift and 45° dump. This gives the
ability to load the 777 in six passes.

visibility, interior sound levels below
75 dB(A), a standard coat hook, cup
holder, storage bin, tinted glass and
intermittent wet-arm wipers. It is also
radio-ready for two radios.
1 STIC™ Control System. Is a revolutionary
system that integrates steering and
transmission into a single controller.
Simple side-to-side motions of the
operator’s left arm turn the machine
right or left. Transmission shifting for
forward, neutral, reverse is controlled by
the operator’s fingers and gear selection
is controlled by the operator’s thumb.
These factors combine to produce a fluid
motion that reduces effort and allows the
operator to work the machine for long
periods of time with little or no fatigue.
2 Left Pedal. Operates the impeller clutch
torque converter for approximately the
first inch of travel, then engages
the brakes.
3 Comfort Series Seat. With air
suspension and retractable seat belt,
including (4) trainer seat and lapbelt,
are designed for comfort and support.
Seat cushions reduce pressure on the
lower back and thighs while allowing
unrestricted arm and leg movement.
The seat has three height levels.
The retractable seat belt stays
off the floor and is easy to reach.
5 Floor-Mounted Hydraulic Controls.
Are attached to the right side of the seat.
They adjust fore and aft, with a heightadjustable armrest so operators of any
size can find a comfortable operating
position.
6 Electronic Monitoring System III
(EMS III). Continually monitors various
machine systems through three instrument
clusters and provides a three-level
warning system to alert the operator
of immediate or pending problems.
EMS III shares information with the
engine, hydraulic and transmission
controls that can be used during servicing
to simplify service and troubleshooting.
7 Axle Temperature Sensor. Detects and
warns the operator of extreme axle cooling
oil temperature through indicator light.
8 Throttle Lock. Allows the operator to
preset the engine speed for a variety of
applications.
9 Rimpull Control System Switch. Turns
the Rimpull Control System on and off.
10 Rimpull Control System (RCS).
Device has four factory preset reduced
rimpull settings. Each setting corresponds
to a maximum allowable impeller clutch
pressure and is user programmable.
When in the reduced rimpull mode, the
left brake pedal modulates rimpull from
the reduced setting (pedal at rest position)
to 20 percent of maximum. This gives the
operator a quick way to return to the
desired reduced rimpull setting and
makes the entire first inch of pedal
travel available for modulating the
reduced rimpull.
11 Optional Payload Control System II.
Offers on-the-go weighing to assist in
loading trucks more accurately. It also
has easy computer download capability.
Payload Control System II Monitor.

Two Separate Hydraulic Systems.
Improve the cooling and help prevent
cross-contamination. One system is for
lift/tilt and brakes, while the other is for
the steering and engine cooling fan.
If one system runs hot or is contaminated,
the other will be unaffected.
Fast Cycle Times. With a high pressure
system make the 990H remarkably
productive. Just 9.2 seconds to raise,
2.9 seconds to dump and 3.8 seconds
to lower.
High Pressure Hydraulic System.
With main lift/tilt relief of 31 000 kPa
(4,500 psi). Main lift/tilt controls are
driven by fixed displacement piston
pumps built by Caterpillar for optimum
pressure was increased for better
response. XT™-3 and XT™-6 hose is
used on the entire machine except for
the pilot lines and reusable coupling
with o-ring face seals are reliable and
reduce the risks of leaks.
Load-Sensing Steering System.
Maximizes engine power. Typical
steering systems can draw more than
30 kW (40 hp) from the engine. The draw
is constant even when the operator is not
steering. The system maximizes
performance by directing power through
the steering system only when it is needed.
For example, in hard digging, when the
machine is not steering, all engine power
is available to generate crowd, breakout
and lift forces. More efficient use of
power results in decreased fuel
consumption and higher production.
Hydrostatic Cooling Fan. Is used for
engine, transmission and hydraulic cooling.
A variable displacement pump drives the
fan’s hydraulic motor so that fan speed
varies with engine rpm. With the optional
high ambient cooling package, the pump
increases output as temperatures increase
for greater cooling capability. The fan
draws only the power needed for cooling,
reducing fuel consumption and
increasing efficiency.
Powerful hydraulics are the invisible force behind the loader’s muscle and flexibility.
