Emission Control System (ECS) Positive Crankcase Ventilation (PCV) System The tractor engine is equipped with a crankcase ventilation system using a ProVent 150 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 and also provides excellent protection for the turbocharger and components fitted downstream.

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.

Removing the Oil Separator 1. Rotate the cover (A) approx. half a turn anticlockwise and remove. If the cover is difficult to move, a tool (e.g. screwdriver) can be used to turn the cover. 2. Pull the oil separator (C) upwards to remove and dispose of as per local waste regulations. Assembly the Oil Separator 1. Clean housing, cover and sealing surfaces. 2. Change O-ring (B) and rub in a small amount of engine oil. 3. Slide the new oil separator into the housing (D) with a new, slightly oiled O-ring. 4. Put on the cover (A) and turn clockwise until it latches into place.

NOTE: Maintenance intervals may need to be shortened depending on the operating conditions. In normal mode, if the O-ring is intact and oil leaks through the bypass valve, this indicates that the oil separator is worn and must be replaced immediately.

Change the PCV oil separator filter and oil pre-separator as per the service schedule. Check the oil separator regularly to ensure that it is free from damage and external soiling.
Always carry out the maintenance work only when the engine is switched off and parked properly. Never start the engine without an oil separator and/or cover. 76
