What is Contamination Control?
Contamination Control, or CC, is a “Proactive
Product Quality Based Initiative” aimed at
improved reliability through cleanliness design
and practices related to the fluids, parts, and
systems of Caterpillar equipment.
Reactive or Proactive?
Contamination Control
Contamination Control – Plants Background/History
Contamination Control...
Awareness
Just a few grains of dust – that light film on the funnel used to
fill the crankcase – the almost negligible amount that might
find its way past an improperly serviced crankcase breather.
Could such small quantities possibly have any appreciable
effect on the life of the engine? The answer is a very positive
YES!
In 1949, we had a basic
understanding of how
contaminants in oil affected
product reliability and durability.
Even in the very early days of
diesel technology, we had a basic
understanding of how
contaminants in fuel affected
product reliability and durability.
Cover of the 1931 Operators’ Guide
1931 Operators’ Guide CARE OF FUEL SYSTEM
The first paragraph on system
care from the 1931 operators
manual states that 90% of
Diesel troubles are due to dirt
or water in the fuel.
Contamination Control – Plants Background/History
• Began Early to Mid 90’s
• Track-Type Tractor Division − Initiated with first time pass test rate
− Cleaned up manufacturing & assembly processes
− Developed commissioning (kidney looping) procedures
• Spread to machine & component plants worldwide
• Specifications & test methods developed − By 1999 all facilities focused on cleanliness
− Assembly reported 100% “Roll-Off” testing
Contamination Control – Plants SUCCESS Formula
CLEAN Facilities
+ CLEAN Components
+ CLEAN Processes
+ CLEAN Fluids
= CLEAN Products
=> Satisfied Dealers & Customers!

How Tough Are Particulates?
Caterpillar: Confidential Green
• Abrasion: Hard contaminates will cut
metals, creating new contaminates
• Fatigue: Contaminates will also fatigue
metals, especially at edges and wear
points, again creating new
contaminates
• Multiplication: It is estimated that each
particle creates 8 – 10 more particles
through abrasion and fatigue
Ref: Bosch Rexroth
The Multiplication of Contaminates

Effects of Contamination on Oil Oxidation Rate
Caterpillar: Confidential Green
62.8°C = 145°F
Ref: Arrhenius’s Law, Backe, STLE
Above 65°C (150°F) increasing the
temperature at which lubricant is stored by
10°C (18°F) doubles the oxidation rate, which
cuts the usable life of the oil in half.

The single greatest opportunity
for increasing component life

to effectively manage fluid

• Nominal Rated
− Media captures the majority of particulate at (60 - 98%) the rated pore size.
− Often stated as the micron size without an efficiency specification
− No industry standard
• Absolute Rated
− Largest particle that will pass through media or largest pore size
− No standard test to determine the value of the pore opening
− Efficiency typically rated at or higher than 98.6% at the micron size.
− Better way to understand effectiveness of the filter compared to Nominal
• Beta Rated
− Best method and most common
− Obtained from multipass testing – ISO 16889
− Number of particles greater that X microns upstream of the filter versus the
number of particles greater than X down stream of the filter.
