Engine Crankcase Breather; Figure 5.7 Air Cleaner, Oil Bath - Carrier RG2059 Series Operation And Service

Air Cleaner, Oil Bath Service Procedure
The oil cup should be inspected during pretrip, before each trip. Never allow more than 1/2 inch (12.7 mm) of dirt
deposit in the cup. More than 1/2 inch accumulation could result in oil and dirt carrying over into the engine, caus-
ing accelerated engine wear. Heavily contaminated oil will not allow the air cleaner to function properly.
Always cover the engine inlet tube while the air cleaner is being serviced.
1. Stop the engine and remove the oil cup from the air cleaner. Dispose of oil in an environmentally safe manner.
2. Remove the inner oil cup from the oil cup and clean both cups.
3. Reassemble and fill both oil cups to the indicated level with oil specified in
Do not underfill or overfill the oil bath cups. Overfilling cups causes loss of capacity; underfill-
ing cups causes lack of filtering efficiency.
Air Cleaner Body Service
The air cleaner body should be inspected each time the oil cup is serviced. If there is any sign of contaminant
buildup or plugging, the air cleaner body should be removed and back flushed.
At least once a year, or at regular engine service intervals, remove the entire air cleaner and perform the following
cleaning procedure:
1. Remove oil cup. Check and clean center tube.
2. Pump solvent through the air outlet with sufficient force and volume to produce a hard, even stream out of
the bottom of the body assembly. Reverse flush until all foreign material is removed.
