Obtaining an Oil Sample
ABOUT THE FS-2500 BYPASS FILTRATION SYSTEM
A filter element has been inserted inside the filter bowl on the FS-2500 filtration system prior to installation on your equipment. It will be necessary to replace that element periodically to maintain the filtration needed to ensure long oil drain intervals and to help increase the life of your engine. The time between filter changes is determined by the conditions in which your equipment is operating. Off-road vehicles need to have the element replaced every 250 hours of operation. The existing full flow oil filters only need to be replaced when it is determined that the oil requires draining or annually, whichever occurs first.
A periodic oil sample analysis program is recommended to monitor the condition of the oil and the condition of the engine. Oil analysis can be used to determine when the oil needs to be drained and replaced. If you would like to know more about how to use oil analysis in your preventative maintenance program we will be happy to help you.
INSTRUCTIONS FOR MAINTAINING THE FS-2500 BYPASS FILTRATION SYSTEM
Turn off engine and allow unit to cool before servicing filter. The filter unit is under pressure while the engine is running. The oil is hot and can cause burns.
Place a drain pan below the filter unit as oil will drip from around the top of the bowl when removed. Loosen 3/4” hex head bolt and support filter bowl to prevent it from falling when the bolt is removed. Remove bowl from head and dump oil and element into drain pan. Remove the square groove gasket from the groove in the head and install the new groove gasket provided. Replace bonded seal under the head of the 1/2” bolt. Insert the new element in bowl and position bowl under the head and install the bolt. Hold the bowl up against head while tightening bolt to ensure bowl aligns squarely into groove. Tighten bolt until bowl seats securely against groove gasket. It should not require more than 40 lb. ft. Dispose of the used element and oil properly according to local disposal codes.
Start the engine and carefully check the system and all the hoses and fittings for leaks. Repair as necessary. The element displaces 1½ quarts of oil and the reservoir will need to be topped off as required after element replacement is complete.
