Follow the procedure for the "A" and "B" series Track-Type Loaders, beginning at Step 9.Oil Compartment Filtration Times for 204-7392 Filter Cart
If an on-line, portable particle counter is not available to diagnose and track when the contaminant level has lowered to an acceptable point, refer to the following equation. This equation relates to the 204-7392 Filter Cart only. Other filtration units will have a different equation reference and will be noted when appropriate. There are various conditions that must be factored into the filtration efficiency of any filter cart and situation. Therefore, the following equation must be viewed as only a simple reference and not an absolute time or efficiency result.Compartment Oil Capacity (gallons) X 2 = Approximate Filtration TimeExample: A 973C Track-Type Loader hydraulic system has 59 L (15.6 US gal) of 10W oil. The approximate filtration time should be about 32 minutes.ISO 4406:1999 Method for Coding the Level of Contamination by Solid Particles
ISO (International Organization of Standardization) is a worldwide federation of national standards bodies. The ISO4406:1999 specifies the code to be used in defining the quantity of solid particles in the fluid used in any given hydraulic fluid power system. An automatic particle counter derives the equivalent size of a particle from the cross sectional area of the particle. Particle counts are affected by various factors. These factors include procurement of the sample, the sample container, particle counting accuracy and where used and cleanliness. Proper care should be taken during sample procurement to ensure that the sample obtained is representative of the fluid circulation in the system.The code for contamination levels using automatic particle counters comprises three scale numbers. ExampleX/Y/Z.X - The number of particles equal to or larger than 4 microns.Y - The number of particles equal to or larger than 6 microns.Z - The number of particles equal to or larger than 14 microns.Currently Caterpillar does not require the reporting of the "X" scale number since the hydraulic tolerances exceed the 4 micron value. Therefore, a "-" is used instead. For example, a particle count is read as -/Y/Z, meaning that there was no requirement to count particles equal to or larger than 4 microns.Clean Out Filter Vs. Filter Cart Filtration
After any "open system" repair, on-site S O S sampling and particle counting is required. This procedure should be accomplished by exercising the specific system until the fluid is at normal operating temperature. Exercising the system ensures
