ENGINE OIL FILTERS

CAT Standard Efficiency Fluid Filters — Engine Oil
• Features standard elements for normal duty filtration.
• Designed to maintain system cleanliness.
• Removes contaminants before the lube oil reaches critical components.
• Available for most CAT equipment models.

CAT Advanced Efficiency Fluid Filters — Engine Oil
CAT Advanced Efficiency Engine Oil Filters provide increased contamination control over Standard Efficiency Filters, without requiring a shortened change interval. And, they are more economically priced than Ultra High Efficiency filters.

Improved Filtering Media
CAT Advanced Efficiency Oil Filters contain an improved filtering media which captures more contaminants, reducing wear on critical oil-lubricated engine components. This results in extended life and improved performance. The graphs below illustrate the efficiency of the 1R-1807 and 1R-1808 filters as compared to their Standard Efficiency Counterparts.

Reserve dirt-holding capacity
Although higher-efficiency filters accumulate dirt more quickly than Standard Efficiency filters, CAT Advanced Efficiency Engine Oil filters do not require a shortened change interval. They feature a reserve dirt-holding capacity, which compensates for the majority of dirt accumulation increase, letting customers maintain standard oil change intervals. The relative dirt-holding capacity of Advanced and Standard Efficiency filters are illustrated in the graph.

Cab Air Filtration Upgrade Options

Not for use in filtering hazardous materials

Odor Reduction Cabin Air Filters
• Caterpillar now offers a selection of charcoal impregnated cabin air filters for use in applications, where odors or airborne irritants are a concern. These filters provide significant odor reduction, but they are not designed to filter hazardous materials.

Compatibility and Fit
• Odor Reduction Cabin Air Filters can be used as direct replacements for standard filters. No modification is necessary, and pressure drop is similar to standard, so there is no adverse effect on air flow, A/C and heat performance, or cabin air pressure. Correct substitutions are indicated in the table below.

Activated-carbon filtering
• Odor Reduction Cabin Air Filters use high-performance activated carbon to quickly absorb odor-causing particles and reduce odors to a comfortable level. A bonded structure holds carbon in place even in high-vibration conditions and prevents carbon dusting. This design also makes the fi lters easy to install and safe to dispose.

Improved particle removal
• Odor Reduction filters also provide higher particle removal efficiency, both initially and throughout filter life. Fewer particles of soil, dust, pollen, mold spores and other irritants enter the cab, even after sustained use.

High surface dust loading
• By holding more dust on the surface, Odor Reduction Cabin Air Filters provide a number of benefits. They last longer, are easier to clean, protect the A/C core from performance-robbing build-up, and reduce maintenance costs for the HVAC unit.

Cleaning and re-use is recommended for Odor Reduction filters under the following circumstances:
• Airflow restriction is increased
• Filter is not damaged
• Filter has been used less than 12 months
• Odor reduction capabilities are still good
• * To clean the filter, use compressed air at 70 psi or less with a 1/8 inch diameter nozzle at a minimum distance of 2 inches.

Replacement Guidelines
• Replace damaged filters, filters used longer than 12 months or filters that no longer reduce odors.



BREATHERS

Retro-Fit Breather Upgrade Options

Function of Breathers
• Breathers are an important part of any professional contamination control strategy. As the volume of liquid changes inside a container (e.g., a hydraulic tank), air must enter and exit the container in order to prevent the container from becoming over-pressurized or in vacuum. Without a breather the exchange of air as it enters and exits tanks introduces air borne contaminants.

Not filtering small air-borne particles results in:
• Pre-mature component replacement
• Lower productivity
• More frequent filter changes

Use of Breathers
• Track-type tractors, stationary engines (industrial, marine, generator sets), motor graders, and Challenger® agriculture tractors are a few product families that have breathers installed on production fuel tanks, hydraulic systems, and gear boxes. Utilizing breathers in order to improve system performance on Caterpillar® production equipment is expanding.
• To improve existing fluid system contamination control, Caterpillar is providing retrofit breathers for field installation on CAT equipment and other manufacturer’s equipment.

Advantage of a Breather
• In general, small particles cause abrasive wear on components and larger particles tend to cause sudden breakdowns by clogging pathways or creating interference between components. Usually, a breather is much less expensive than a filter, and its use can increase the service interval for the filter. In systems where air is forced out through the breather, such as in hydraulic or fast fill applications, the dirt is blown out of the element, thereby increasing its life.

Breather Selection
• The level of breather filtration required in a system depends on the application. The more sensitive to contamination the system is, the greater the need for filtration.

General Rule of Thumb
• Efficiency - Higher breather efficiencies will maintain a cleaner system.
• Restriction - If air flow capacity is in question, use the larger breather.
• Location - When choosing the location for the breather, make sure that it is as convenient as possible to inspect and change: good clearance and visual line.

Change intervals:
• Breather change interval can vary widely depending on extremes in operating conditions. As a general rule, change breathers with every fluid change or when breather vent slots appear clogged.

Inspection:
• Include visual inspection of breathers in routine maintenance inspections. If in doubt, change the breather. The cost of a new breather is minimal in comparison to the potential downstream costs of not changing it.



HYDRAULIC AND POWER TRAIN FILTERS

Choosing the Correct CAT Hydraulic Filter
The CAT Hydraulic Filter line now includes Standard, Advanced Efficiency and Ultra High Efficiency (UHE) filters, providing our customers the best selection and the best engineered protection available anywhere.

Selection Guidelines
In order to choose the right filter for your machine, always begin by consulting the maintenance manual for proper change interval and recommended filter part numbers. It is usually safe to substitute a higher-efficiency filter, but NEVER substitute a lower efficiency filter than the one recommended.

If your transmission or hydraulic system has a filter bypass dash indicator and a Standard filter is recommended, you can use an Advanced Efficiency or UHE. If you do not have a bypass indicator, consult your CAT Dealer before upgrading.

Selection Guidelines
• In order to choose the right filter for your machine, always begin by consulting the maintenance manual for proper fit and installation.

Upgrade Procedure and Intervals
• Higher efficiency filters can clog sooner because they trap smaller particles which standard filters do not.



CRANKCASE VENTILATION (CV) FILTERS

For CAT C13 and C15 On-Highway Diesel Engines

It takes a true system approach to engine design to meet the need for high performance and protect air quality at the same time. Every part of the engine has an important role to play, especially the filters.

The CAT CV Filter (part number 296-8325) is an important part of the emissions reduction strategy employed on CAT C13 and C15 on-highway engines to meet 2007 EPA emissions standards.

Smart Design
The CAT CV Filter incorporates the housing end cap, o-ring seals and ultra-high efficiency media into one convenient, compact unit for ease of maintenance.

The ultra-high efficiency media element removes vaporized oil droplets and particulate matter from the crankcase blow-by stream. Oil returns to a liquid state as it passes through the media. The oil is then captured in the filter housing and recycled back to the engine’s oil sump. At the same time, particulate matter and contaminants are trapped in the media. Cleaned blow-by is routed to the atmosphere through the CV system’s outlet tube.

Easy to Service
Replace the CAT CV Filter at the oil change interval recommended in the Operation and Maintenance Manual. Customers using extended oil drain intervals may need to change the filter at intervals differing from the extended oil drain interval.

No special tools are required. To remove the old filter, unscrew the used element from its housing and discard following local filter disposal regulations. To install a new filter, lubricate the o-rings with clean engine oil, thread into the housing and tighten to 25 N-m. Do not over tighten.
