<h2>
<span style="color: #003d84;">4000 Hour Oil Change Interval</span></h2>
A 4000 hour maintenance interval for hydraulic oil (change) is available. The 
extended interval requires S·O·S monitoring of the hydraulic oil. The interval 
for S·O·S monitoring is every 500 hours. The maintenance interval for the 
hydraulic oil filter is not changed. If S·O·S monitoring is not performed, the 
2000 hour maintenance interval must be used.
<br />
Machines with hammers are not included in the 4000 hour maintenance interval. 
Machines with hammers must use the intervals that are listed in the Maintenance 
Interval Schedule. Machines that are used in severe conditions are not included 
in the 4000 hour maintenance interval. Machines that are used in severe 
conditions must use the interval in the Maintenance Interval Schedule.

<h2>
<span style="color: #003d84;">Introduction</span></h2>
This Guideline enables dealers and the dealer's customers to benefit from 
cost reductions which were made possible through an established Contamination 
Control Program. Fluids used in Caterpillar machines are highly effective unless 
the fluid contains damaging amounts of contaminates. Therefore, every effort 
must be made in order to reduce the contamination level within Caterpillarfluid 
systems. Caterpillar makes ongoing changes and improvements to the Caterpillar 
products. This guideline must be used with the latest technical information 
available from Caterpillar in order to ensure that such changes and improvements 
are incorporated when applicable.

<h2>
<span style="color: #003d84;">Summary</span></h2>
The following special instructions explain the use of the Caterpillar filter 
system <b>285-8095 </b>filter system to prepare bulk quantities of new 
Caterpillar oils to meet fill oil requirements. The filter system combines a 
1249 L (330 US gal) non-metallic storage reservoir with a filtration system. 
This filtration system has been validated by Caterpillar to remove contaminants 
that may be found in new oils shipped to Caterpillar facilities and dealerships. 
By following the instructions in the Filtration Procedure section below, new 
oils can be filtered to a cleanliness level of ISO 16/13. Caterpillar recommends 
that an automatic particle counter be used to initially verify the performance 
of the filter system in preparing fill oils. After the initial validation, 
automatic particle counts do not have to be completed every time, but audits 
should be routinely completed to assure the filter system continues to perform 
to specification. <a href="https://www.blogger.com/null" name="#003"></a>

<h2>
<span style="color: #003d84;">ISO 4406:1999 Method for coding the level of contamination by solid 
particles</span></h2>
ISO (International Organization of Standardization) is a worldwide federation 
of national standards bodies. The ISO 4406:1999 specifies the code to be used in 
defining the quantity of solid particles in the fluid used in any given 
hydraulic fluid power system. An automatic particle counter derives the 
equivalent size of a particle from the particle's cross sectional area. Particle 
counts are affected by a variety of factors. These factors include procurement 
of the sample, the sample container, particle counting accuracy and where used 
and its cleanliness. Proper care should be taken during sample procurement to 
ensure that the sample obtained is representative of the fluid circulation in 
the system.
<br />
The code for contamination levels using automatic particle counters comprises 
three scale numbers. ExampleX/Y/Z.
<br />
"X" is the number of particles equal to or larger than 4 microns. "Y" is the 
number of particles equal to or larger than 6 microns. "Z" is the number of 
particles equal or larger than 14 microns.
<br />
At this time Caterpillar does not require the reporting of the "X" scale 
number since the hydraulic tolerances exceed the 4 micron value, therefore a "-" 
is used in its place. For example, a particle count is read as -/Y/Z, meaning 
that there was no requirement to count particles equal to or larger than 4 
microns. <a href="https://www.blogger.com/null" name="#007"></a>

</span>
<h2>
<span style="color: #003d84;">Filtration System Description</span></h2>
The complete bill of materials and instructions for operating the filter 
system are included in the Tool Operating Manual, NEHS0957. Following is a brief 
description of the major components of the filter system and why they are an 
important part of preparing new oils to fill Caterpillar machines and engines. A 
schematic is also attached at the end of this guideline. <a href="https://www.blogger.com/null" name="#008"></a>
<br />
<u>
</u>
<h3>
<u>330-Gallon Non-Metallic Reservoir</u></h3>
An essential requirement of the Filtration Procedure is that fill oils must 
be contained and stored in clean reservoirs during and after the process. The 
best way to accomplish this is by using a non-metallic reservoir or tote. One 
such tote is included with the filter system and additional units may be added 
to meet the specific needs of different Caterpillar facilities and dealers. See 
the 3-Way Inlet and Outlet Valves section below. <a href="https://www.blogger.com/null" name="#009"></a>
<br />
<u>
</u>
<h3>
<u>Centrifugal Pump</u></h3>
A centrifugal pump driven by a 3-phase electric motor is used to steadily 
circulate the oil through filters that remove debris and water contamination. 
Steady flow without interruptions and flow surges can be achieved by using 
centrifugal type pumps that maintain a uniform fluid velocity across filter 
elements. The steady flow of the centrifugal pump is preferred over the 
interrupted flow of a reciprocating pump. This uniform fluid velocity is 
necessary for the Filtration Process described below. <a href="https://www.blogger.com/null" name="#010"></a>
<br />
<u>
</u>
<h3>
<u>Ultra-High Efficiency Filter Elements</u></h3>
Removal of fine debris down to particle sizes of 6 microns and smaller is 
necessary to provide the cleanest possible fill oils. This cleanliness level is 
accomplished with filter elements designed specifically for Caterpillar. They 
have the same quality construction and excellent dirt holding capacity as the 
elements used on Caterpillar machines and engines. <a href="https://www.blogger.com/null" name="#011"></a>
<br />
<u>
</u>
<h3>
<u>Water Removal Filter Element</u></h3>
In many cases new oils have been found to contain free and emulsified water. 
Water vapor may also be present in new oils and depending on ambient conditions, 
it may change phase and become emulsified in the oil. Water droplets in 
lubricating oil will interfere with automatic laser particle counters and should 
be removed if possible. In addition, water levels of 0.1 percent by volume may 
be harmful to Caterpillar machines and engines and must be removed from fill 
oils. The water removal element included in the filter system has been selected 
and placed in a location where it will work in conjunction with the Ultra-High 
Efficiency filter elements to remove water contaminants. <a href="https://www.blogger.com/null" name="#012"></a>
<br />
<u>
</u>
<h3>
<u>Water Absorbing Tank Breather</u></h3>
The importance of water removal is addressed above. A tank breather is 
necessary to allow the air motion that occurs when filling a reservoir or when 
using the Filtration Procedure. The breather included with the filter system 
will remove airborne contaminants down to 4 microns and absorb some of the 
moisture present due to local ambient conditions. A desiccant color indicator is 
used to determine when the breather needs to be changed. Breather life will vary 
depending on the level of contamination and moisture in the air. <a href="https://www.blogger.com/null" name="#013"></a>
<br />
<u>
</u>
<h3>
<u>Filter Restriction Indicators</u></h3>
The filter system includes a pressure differential gauge on the ultra-high 
efficiency filter bank and a pop-up restriction indicator on the water removal 
filter housing. These can be used to indicate when filter element service is 
required. Refer to the Tool Operating Manual, NEHS0957. <a href="https://www.blogger.com/null" name="#014"></a>
<br />
<u>
</u>
<h3>
<u>3-Way Inlet and Outlet Valves</u></h3>
3-way valves on the centrifugal pump inlet and the return line to the 
non-metallic reservoir are included with the filter system. These can be used to 
change the flow path of the oil. Oil may be drawn from or returned to an 
external reservoir other than the 1249 L (330 US gal) tank included with the 
filter system. With proper positioning, the 3-way valves can be used to 
initially fill and filter oil in an additional reservoir. If the additional 
reservoir is another 1249 L (330 US gal) non-metallic unit, the filtration 
procedure below can be used for as many of these units as desired. For 
instruction on the proper settings for the 3-way valves refer to the owners 
manual and operating instructions for the Caterpillar filter system. Refer to 
the Tool Operating Manual, NEHS0957. <a href="https://www.blogger.com/null" name="#015"></a>
<br />
<span style="color: #003d84;">
</span>
<h2>
<span style="color: #003d84;">Filtration Procedure</span></h2>
Oil that will be prepared to fill Caterpillar machines and engines must first 
be transferred to the 1249.1853 L (330 US gal) non-metallic reservoir. The 
centrifugal pump of the filter system may be used to accomplish this if the oil 
temperature (viscosity) and the hose length to the storage reservoir are each 
low enough to prevent pump cavitation. Refer to the Tool Operating Manual, 
NEHS0957. During the process of transferring oil a sample bottle of the oil that 
will be prepared must be taken. This sample should be examined carefully with 
the naked eye. If visible debris or water is apparent an automatic particle 
count will be required at the end of the filtration time specified in Table 1. 
The particle count will verify whether or not the oil is ready to fill 
Caterpillar machines and engines. Heavily contaminated oil should not be run 
through the automatic particle counter. <a href="https://www.blogger.com/null" name="#016"></a>
<br />
<u>
</u>
<h3>
<u>Estimated Filtration Time</u></h3>
If the oil is below 25 °C (77 °F) the oil must be warmed for the following 
instructions to be valid. In order to reach fill oil cleanliness levels of ISO 
16/13 for fluid power circuits, the oil in the filter system reservoir must be 
cycled through the filters 12 to 14 times. The process has also been shown to 
work on engine oils. With a proper pre-treatment procedure to reduce particle 
counts caused by additives in the oil, ISO cleanliness levels of 16/13 or better 
can be achieved for engine oils, which contain the most additive by volume. To 
achieve the 12 to 14 cycles through the filters, the following table of minimum 
estimated filtration times has been developed. See table 3 below, which lists 
the required filtration time for different volumes of oil contained in the 
storage tank of the filter system filter cart. Once the oil in the reservoir of 
the filter system filter cart has been cycled through the filters for the 
minimum time interval specified in table 3 it is ready to be used as a fill oil 
for Caterpillar machines and engines. The oil will remain in this condition for 
up to 14 days.

</tbody></table>
It is important to note that these are the minimum filtration times. Studies 
have shown that oil additive levels will not be harmed if these minimum times 
are slightly exceeded. However, extremely long periods of filtration are not 
recommended. Oil stored in the reservoir for periods longer than 14 days should 
be cycled through the filters again for the time interval indicated in 3. Do not 
exceed a total filtration time of 30 hours for a 1249.1853 L (330 US gal) or 
smaller volume of any Caterpillar fill oil. <a href="https://www.blogger.com/null" name="#017"></a>
<br />
<u>
</u>
<h3>
<u>Automatic Laser Particle Counters</u></h3>
Caterpillar facilities and dealerships that want to accurately measure the 
fill oil ISO cleanliness level using an automatic particle counter should use a 
pre-treatment procedure to offset the possibility that oil additives may be 
counted by the automatic particle counter as contaminant debris. Instructions 
for the pre-treatment procedure are detailed in Caterpillar publication oil 
sample pre-treatment procedure,Contamination Control Guideline, SEBF9086. It is 
recommended that this procedure be used initially to verify the performance of 
the filter system. The automatic particle counter should also be used to 
routinely audit the cleanliness of the new oils.
