KNOB AS 1859208 - Caterpillar

A probe is available that allows the valve to be quickly flushed prior to taking oil samples.
The sample bottle group is sealed in a plastic bag to insure cleanliness. Using the 8T9190 Bottle Group results in minimal exposure to atmospheric contamination compared to suction sampling methods. When the bottle is removed from the plastic bag, it is ready for use. After taking the oil sample, the probe and tube are separated from the bottle cap and discarded. The cap cover is snapped to the bottle cap, sealing the bottle.
A mailing container is available so the oil sample can be conveniently mailed to the testing laboratory.
Live oil sampling is a fast, economical and clean method of obtaining oil samples from pressurized systems. Pressurized systems include engine, transmission, and hydraulic systems. Systems may also include hydraulic steering or other hydraulic systems that are isolated or considered separate pressurized systems.
Live oil sampling is 10 to 20 times faster than sampling oil from nonpressurized systems. It takes approximately 10 seconds per port to flush the valve and take an oil sample. The engine should be at low idle rpm when the oil samples are taken and all compartments should be at normal operating temperature. Downtime is further minimized when live oil samples are obtained because the engine does not have to be turned off.
