Kleenoil Trial - John Deere 9560 Hydraulics

To prove the effectiveness of the Kleenoil Bypass Filter units on hydraulic systems, a John Deere 9560RT tractor was outfitted with a KU 50. Because implements are changed frequently, hydraulic systems are prone to contamination, which increases abrasive wear on hoses and critical internal components.

According to industry experts, 82% of mechanical wear is caused by particle contamination. To maximize component life, equipment manufacturers machine components to tight tolerances that dictate how clean the hydraulic fluid needs to be. A John Deere 9510RT uses a variable piston pump and fluid power specialists recommend a maximum contamination ratio of 16/14/12 under the ISO 4066 cleanliness system. ISO cleanliness is a more precise metric than the Millipore method as it identifies the size and concentration of particulate contaminants instead of just an overall weight.

Hydraulic oil samples were taken before installing the Kleenoil Bypass Filter system and 850 hours after. The results below show that the original oil cycling through the hydraulic components of this tractor was well beyond the recommended cleanliness. Allowing the fluid to circulate through the Kleenoil filter removed over 400,000 particles per mL (99% of original contaminants) and brought the hydraulic fluid back to within standards.

The Noria Corporation publishes Life Extension tables based on improved cleanliness for various kinds of fluid systems. From the original ISO 23/22/18 code to the filtered ISO 16/13/9 code, an extension of component life can be estimated at 7 to 9 times.
