Filter Element Cleaning
Clean the filter element using one of the following methods:1. Using clean, dry air, at a pressure not to exceed 100 PSI, proceed as follows: Direct air against the inside of the element to loosen any imbedded dirt. Best results can be obtained by moving the air hose so that air is directed along the complete length of each pleat.Blow off loose dirt by directing air against the outside of the element. Repeat this procedure until the element is clean. Make certain that no dirt is inside the element.2. Using clean water, at a pressure not to exceed 40 PSI, proceed as follows: Direct water against the inside of the element to loosen any imbedded dirt. Best results can be obtained by using a water hose without a nozzle and moving it so that water is directed along the element.Wash off loose dirt by directing water against the outside of the element.Repeat this procedure until the element is clean. Make certain that no dirt is inside the element, and thoroughly dry the element before installing it.3. Some oily and/or sooty deposits can be removed by washing the element in a solution of warm water and a good household non-sudsing detergent. Rinse with clean water and dry as in "2" above.Diesel Engine Oil Bath Type Air Cleaner
The air cleaner does its work efficiently only as long as the oil in the cup is thin enough to flow freely, so it will spray into the filter section and wash back the dirt collecting there. For this reason, the air cleaner should be inspected frequently and serviced according to the following instructions. Inspect the Oil in the Diesel Engine Air Cleaner Cup: Every 10 to 50 service hours, depending upon the operating conditions, inspect the oil in the diesel engine air cleaner cup. The air cleaner cup should be washed and refilled every 50 service hours or when the oil in the cup will not flow freely at operating temperature, or if the sediment in the cup is 1/2 inch deep, whichever occurs first.1. Loosen the wing nuts and take off the diesel engine air cleaner cup and separable tray.Some thickening of the oil in the cup should be no cause for alarm, actually it can be considerably thicker than the SAE grade that was last put in the cup, as long as the oil at operating temperatures will flow freely. For a check to determine if the oil will flow freely, dip into the oil with a finger and if the oil on it will flow off, the oil is fluid enough to flow freely.2. Service other parts of the air cleaner while the oil cup is removed, as indicated in the following topics.3. When refilling the oil cup, care should be taken to see that both the inner and outer cups are filled to the flat face of the inner cup and to the oil level bead on the starting engine air cleaner cup. In temperatures above
