STRIP (R.H. Inner-L.H. Outer) 9S8354 - Caterpillar

The Closed Crankcase Ventilation (CCV) system contains four individual coalescing filter assemblies (two on each side of the engine).The Closed Crankcase Ventilation (CCV) system requires the replacement of the fumes disposal filter. The service interval of the CCV will be affected by the following items:
Engine load
Concentration of soot
Condition of the engineThe CCV system has sufficient capacity to meet the maintenance interval schedule under normal operating conditions. Engine crankcase pressure will indicate the need for replacement if the CCV filter elements become restrictive prior to the scheduled maintenance interval.Replacing the Fumes Disposal Filter
Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Note: Shut down the engine prior to performing fumes disposal filter maintenance.
Failure to perform this maintenance at less than 1500 hours will not void the emissions-related warranty.
