Emission Control System (ECS) a. Positive Crankcase Ventilation (PCV) System The tractor engine is equipped with a closed type crankcase ventilation system using a Fleet-Guard oil separator. This separates the oil efficiently from the engine blow-by gases through a high performance media, maintains the crankcase pressure within acceptable safe limits. The maintenance of the PCV system essentially involves replacing the oil separator filter media. The oil filter media must be replaced after 1500 operating hours as indicated in the service schedule for continued performance of the engine.

NOTE: Maintenance intervals may need to be shortened depending on the operating conditions. Remove the hose connections at the turbocharger inlet, intercooler inlet, outlet and EGR mixer pipe inlet ends and check for oil precipitation. Thin layer of oil mist on inner walls is normal. If oil droplets are heavy, then the oil separator element and preseparator need to be replaced.
