IntroductionThis Guideline enables dealers and the dealer's customers to benefit from cost reductions which were made possible through an established Contamination Control Program. Fluids that are 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 Caterpillar fluid 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.For questions or additional information concerning this guideline, submit a feedback form in the Service Information System website. In order to address an urgent need, please use the following to relay your request to Caterpillar Repair Process Engineering:

If a Contatmincation Control Guideline is required, but not available in SIS Web, submit a feedback form in the Service Information System website.

SummaryA good oil sample that accurately represents the condition of the fluid system is vital for the success of any analysis program. For this reason, the oil should be at the system operating temperature or at least 50 °C (120 °F) if the normal operating temperature cannot be reached when the sample is taken. The following guideline describes the methods in order to obtain oil samples from machine fluid systems. Bottle sampling (pressure and suction) and portable particle counter methods are included in this guideline. These processes are used when an oil sample is taken or when an on-line particle count is taken on any fluid system (such as hydraulic, steering, power train, engine and final drive).

Zero Pressure System Using a Hand Vacuum Pump



Parts List Quantity Part Number Part Description 1 162-5791 Shop Towel 2 169-8373 Sample Bottle Group 1 1U-5718 Oil Sampling Vacuum Pump 1 4C-4600 Sample Bottle Shipping Container 1 1U-7648 Tube Cutter 1U-8757 Tube

Table 4


Note: Typical nonpressurized systems are reservoirs, differentials, final drives, or return lines (drains). The sample location should be near the middle of the reservoir's fluid level and away from the sidewall. The sample location should be where the fluid is normally in motion, thoroughly mixed, and at normal operating temperature. The sample should be taken as soon as possible after the machine exercising has been stopped. Prepare all sampling hardware before an oil sample is taken.Note: Never use the same vacuum pump for obtaining both oil and coolant samples. Although the fluid does not enter the barrel of the pump, a small residue of glycol from the coolant remains in the pump and can contaminate the oil sample. This will indicate a "false positive" coolant leak in the oil system being sampled.




Fill out the S·O·S label. Pay special attention to the serial number, sample data, service meter units on equipment, service meter units on oil, oil type, oil brand and the amount of oil added. Indicate if the oil was changed after the sample was taken.

1.


1U-8757 Tube cut to length

Measure the tubing and then cut new 1U-8757 Tubing to the length of the dipstick. If there is no dipstick, cut the tubing so that the tubing reaches about halfway into the oil depth of the compartment being sampled.

2.

Note: Use a 1U-8757 Tube Cutter in order to prevent the tubing from being contaminated.




Install tubing into the 1U-5718 Vacuum Pump . The bottle end of the tubing should be approximately 25.4 mm (1 inch) beyond the base of the vacuum pump head.

3.


Install a new bottle to be sampled to the vacuum pump.4.


Store the vacuum pump assembly and store the clean bottle cap in the plastic bag until the parts are ready for use.

5.

Exercise the machine fluid to be sampled until the fluid system is up to normal operating temperature. If normal operating temperature cannot be reached, then 50 °C (120 °F) is acceptable.

6.

Park the machine on level ground. Lower all the attachments. Engage the parking brake.7.Shut the machine off. Make sure that all the systems are in safe positions. Refer to the Operation and Maintenance Manual.

8.




Clean the sample location using a clean 162-5791 Lint Free Shop Towel .9.


Keep the sample bottle vertical when taking samples. Pump the vacuum pump handle in order to create a vacuum.

10.

Note: If the bottle is tilted, the oil will enter into the suction of the barrel of the vacuum pump. This will cause cross contamination of subsequent samples.




Fill the sample bottle half full with system oil.11.Remove the bottle from the vacuum pump.12.


Install a clean lid and shake the bottle vigorously for several seconds.13.




Empty the bottle into a waste oil container.14.reinstall the sample bottle to the vacuum pump.15.


Take the oil sample in the same manner. Fill the bottle to the "fill range".16.Note: Do not fill the bottle beyond the fill mark. This will not allow for proper lab mixing.




When the oil bottle is filled, remove the bottle from the vacuum pump. Cap the bottle with a clean lid (no holes).

17.

Clean the outside of the bottle.18.


Place the bottle with the completed information label into a 4C-4600 Shipping Container or take the bottle and the label to the lab.

19.

Remove the tubing from the vacuum pump and discard the tubing in the probe location.20.




Clean any covers, caps, plates, etc that have been removed.21.
