Komatsu Oil and Wear Analysis (KOWA) is Komatsu's oil sampling system. It supports a regular, planned maintenance program for your equipment by analyzing your oil to help predict premature failure.

KOWA Kits are available from any C.N. Wood location. The kit includes a plastic container, instructions, field sample report form and a mailing container. The cost of the oil analysis is also included in the purchase price of the kit.

Oil Analyses
An independent laboratory conducts two types of tests on the oil samples—physical and spectrochemical. Physical analyses measure the physical characteristics of the oil, including viscosity, fuel dilution, oxidation and nitration, and concentrations of water, glycol and fuel soot. Spectrochemical analyses identify and measure 21 specific elements, including iron, copper, aluminum and silicon, which may otherwise be undetectable.

Test Results
Precise, easy to understand reports are provided by fax, through the mail or on an electronic bulletin board system over the Internet. Through these reports, the wear and performance conditions can be assessed for internal, oil-wetted components such as engines, transmissions and hydraulic systems. These detailed reports also include maintenance recommendations, which are produced from an equipment trends tracking program, so that you can schedule maintenance well in advance. Field service representatives from C.N. Wood can help you translate the results into maintenance strategies.

Oil Sampling Frequency
Check your OEM specifications handbook for recommended oil sampling intervals.

Komatsu has a data management system that stores the results of the oil analyses, called Lube Oil Analysis Management System (LOAMS). Historical data is stored on-line where graphs, reports and comprehensive recommendations can be accessed.

How to obtain a used oil sample with a sampling pump
1. Remove the lid from the sample bottle. Screw the bottle into the sampling pump. Make sure the bottle is sealed against the Oring in the pump, but do not over tighten.
2. Insert sampling pump tubing into the dipstick opening, using the length of the dipstick to measure the length of the plastic tubing.
3. Draw a vacuum with the sampling pump until oil begins to flow into the bottle. Continue pumping until the bottle is full to the shoulder, then loosen the bottle to release the vacuum. DO NOT withdraw the tube. This is your test draw. Discard drawn oil and bottle; it is contaminated.
4. Attach new bottle and fill. This is the sample you are submitting.
How to obtain a used oil sample when the compartment is drained
1. Wipe the area around the drain plug as clean as possible.
2. Remove the drain plug and allow about one-third of the oil to drain from the compartment.
3. While the oil is flowing from the compartment, fill the sample bottle, taking care not to contaminate the oil.
4. Allow the compartment to drain completely and replace the plug.

General guidelines
Follow these guidelines to insure that the sample you are sending to the laboratory for analysis is representative of the machine's oil.
• Oil temperature—Obtain an oil sample as soon as possible after
 turning off the engine, while the oil is still close to operating
 temperature. Be careful to avoid burns.
• Container requirements—Use a clean container for the sample.
• Mark vehicle, compartment on labels—Are you sampling oil from
 several machines at the same time? Be sure to identify the correct
 vehicle and compartment on each container and each mailing label.
• Sealing—The lid on the container should be closed tightly, but not too
 tight. Place the container into a plastic bag, seal with a twist tie, then
 place it into the shipping carton.
• Complete report and seal carton – Complete all requested
 information: SMR reading, accurate and consistent
 Make/Model/S/N data, sampling component, date, make up oil,
 brand, oil viscosity, applicable comments ( e.g., specific contaminate
 you are searching for).
• Multiple samples—If you are sending several samples at the same
 time, package them in the individual cartons, then place these
 cartons into a larger box for one bulk shipment.
• Send out the sample—Send the sample to the laboratory using the
 fastest delivery method available.
• Maintain a consistent routine for all oil sampling processes to assure
