Milton CAT D11T CD - Manual (Page 10)

Torque Divider. A single-stage torque
converter with output torque divider
sends 75 percent of engine torque
through the converter and 25 percent
through a direct drive shaft for greater
driveline efficiency and higher torque
multiplication. The torque converter
shields the driveline from sudden torque
shocks and vibration.
High Torque Multiplication. The more
efficient and better matched torque
converter provides high drawbar pull
reserves at converter stall. High torque
multiplication gets heavy loads moving.
Elevated Final Drives. Isolated from
ground and equipment induced impact
loads for extended power train life.
• Double-reduction, planetary final
drive gears provide smooth, quiet,
low-maintenance operation.
• Splash lubrication and Duo-Cone ®
Seals extend service life.
• Gears and planet carriers are sized
for higher loads and increased
durability.
• Axle and spline have been enlarged
for higher torque.
Planetary Power Shift Transmission.
Three speeds forward and three speeds
reverse, utilizing large diameter, high-
capacity, oil-cooled clutches.
• Modulation system permits fast
speed and direction changes.
• Modular transmission and bevel
gear slide into rear case for servicing
ease, even with ripper installed.
• Oil-to-water cooler for maximum
cooling capacity.
• Forced oil flow lubricates and cools
clutch packs to provide maximum
clutch life.
• Controlled throttle shifting regulates
engine speed during directional
shifts for smoother operation
and longer component life.
• Size of bevel group unit increased
for higher torque.
Electronic Clutch Pressure Control.
The Finger Tip Control (FTC) system
has an additional drive train feature for
added performance, Electronic Clutch
Pressure Control (ECPC). This feature
provides smoother shifting by modulating
individual clutches. ECPC also provides
the auto-shift and auto-kickdown feature.
Auto-Shift/Auto-Kickdown. Auto-shift
allows the operator, by just making a
directional change, to go from first
forward to second reverse.
Auto-kickdown automatically downshifts
the transmission when significant load
increases are detected. These features
are especially useful in backfilling or
rough grading applications or with a
less skilled operator. Depending on
application, operators can select auto-
shift mode only, auto-shift and auto-
kickdown mode, auto-kickdown mode
only, or manual mode. The operator
may override these automatic shift
features at any time.
D11T Brakes. The brakes are applied by
springs and hydraulically released for
safe and reliable braking performance.
• Thick, large diameter plates and
disks provide high torque capacity
and service life.
• Brake housing has cast-in-ribs
for more durability and a new
valve design.
• Cooling oil valve controls 284 L
(75 gal) of oil per minute.
• Clutch disks allow greater torque
capacity on the clutch.
• Tapered roller bearing design
provides excellent service life.
Drawbar Pull vs Ground Speed.
As loads on the tractor increase,
the D11T offers unmatched lugging
capability and smooth shifting as the
need occurs to change gears under
varying loads. The 3-speed forward,
3-speed reverse transmission offers
excellent runout speeds.
Modular Power Train. The modular
power train design permits quick
removal and installation of major
components such as the engine,
transmission and final drives.
