Magnom Inline Filters Installed on Cat D11R Fan Drive Circuit
Fan drive systems were suffering from accelerated wear, causing premature component failures and costly repairs. The Whayne Technology Division has installed MAGNOM in-line units to protect and significantly improve the life of the fan drive motor and other hydraulic components.
The best location for the Magnom in-line filters is at the front of the machine behind the radiator grill/guard.
Two Magnom in-line filters were used in this application. The filter on the left is a Max low pressure (1500 psi & 46 gpm max flow) installed on the return line. The filter on the right is a high pressure CP20 (4000 psi & 46 gpm max flow) located on the supply line.
The low pressure Magnom Max is the easiest filter to remove and inspect the core.
Close up of Magnom Max Core on 7/28/08 after 500 hours of use. Note ferrous particles that have been removed from the machines hydraulic system. This prevents these particles from infecting other hydraulic components on the machine. Rule of thumb...1 ferrous particle can create 40 particles. Magnom helps to stop the chain reaction of wear caused by these micron sized ferrous particles.
Above is a photo of the Max core after 24 months of service. Note that the core has far fewer ferrous particles. This is very typical of Magnom installs. The ferrous collection of particles is normally very heavy in the first 100 hours after the filter is installed. After the core is cleaned and reinstalled, the collection of particles does decline due to the system being ultra clean. Eventhough the Magnom filters are installed on the fan drive circuit, the rest of the machine's components benefit from the "kidney-looping" effect of all the oil flowing through this circuit. The end result is improved lifes of all hydraulic components on the machine.
