Milton CAT D8T Tier 4 Interim-Stage IIIB - Manual (Page 10)

Cooling
System
Durable and efficient
The engine radiator, Air To
Air After Cooler (ATAAC) and
hydraulic oil cooler are packaged
in a single plane. Aluminum bar
plate construction aids durability
and allows for higher heat transfer
and superior corrosion resistance.
The standard cores feature 6 fins
per inch to allow debris to pass
through and reduce plugging
concerns.
In cooler conditions, a Hydraulically
Driven Demand Fan reduces speed
to conserve power, save fuel, and
decrease sound levels.
An optional Reversing Fan can
be set to change air flow direction,
efficiently removing debris from the
cooling cores without the operator
leaving the cab. To improve core
serviceability, the cooling package
also includes air wand or brush
access slots. The ROPS mounted
air conditioning system works
with the reversing fan for optimum
fan purging and ambient cooling
capability.
Undercarriage
Engineered for performance
The D8T features the Cat elevated sprocket design that isolates final drives,
axles, and steering components from harsh impacts. The modular design aids
serviceability to help reduce maintenance costs. A variety of undercarriage
configurations and track shoe designs help optimize performance and
undercarriage life.
Heavy Duty Undercarriage with Positive Pin Retention Moderate Service Sealed
and Lubricated Track (SALT) is standard. This undercarriage is well suited to
aggressive applications like land clearing, side-slopes, or working in rocky or
uneven terrain. Components are designed for extended wear life in abrasive
conditions and high impact applications.
SystemOne™ Undercarriage is available as an option and can help reduce total
undercarriage owning and operating costs in many applications. SystemOne features
lifetime sealed and lubricated cartridges to eliminate bushing turns, and sprockets
require no replacement during the life of the chain. All SystemOne undercarriage
components are designed to work and wear as a system for longer track life.
