(1) Crankcase breather
(2) Restriction indicator
(3) Line to air cleaner
(4) Fumes disposal filter
(5) Drain line to crankcase Fumes flow from the crankcase through crankcase breather (1) to fumes disposal filter (4). The oil in the fumes is separated from the air by a filter assembly. The air is routed to the turbochargers via line (3) so that the filtered blowby gas is recycled through the combustion system.Oil that is separated from the fumes is collected in the bottom of the filter housing. The oil is returned to the engine crankcase via drain line (5), which is routed through a crankcase side cover. Crankcase pressure is maintained through an internal spring setting in the filter.Restriction indicator (2) is on top of the fumes disposal filter. Check the restriction indicator during the daily maintenance. The filter assembly must be replaced when the restriction indicator is activated.
