Cummins 5.9/6.7L Single-Remote Bypass Filtration System
BMK34 Installation and Servicing Instructions
See Bypass Installation Samples
*Notice: System does not include oil filter adapter. Check top of full-flow oil filter housing for two plugs. System includes fitting options to replace one plug. If both plugs are not accessible, order optional part BK1104. See BMK34 Installation and Servicing Instructions above for more information.
The Ea Bypass Oil Filter (EaBP) provides the best possible filtration protection against wear and oil degradation. Working in conjunction with the engine’s full-flow oil filter, the AMSOIL Ea Bypass Filter operates by filtering oil on a “partial-flow” basis. It draws approximately 10 percent of the oil pump’s capacity at any one time and traps the extremely small, wear-causing contaminants that full-flow filters can’t remove. The AMSOIL Ea Bypass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.
Higher Efficiency
AMSOIL EaBP Filters have an efficiency of 98.7 percent at two microns. At normal operating RPMs the EaBP Filter will filter all of the oil in a typical five quart sump in less than 10 minutes; around 20 minutes for larger crankcases.
Superior Construction
The superior construction of AMSOIL EaBP Filters provides better sealing and increased longevity along with superior corrosion resistance. AMSOIL EaBP Filters have a marine powder coated exterior; and their zinc-dichromate base plates increase rust protection. EaBP Filters have a nitrile HNBR gasket and an orange silicone anti-drain valve. The two stage pleated and layered cellulose/full synthetic media has an efficiency rating of 98.7 percent at two microns.
Longer Lasting
AMSOIL Bypass Filters can be utilized over an extended period of mileage, hours or years as outlined in the Chart below. Oil analysis is recommended for extended drain intervals.
Increased Oil Capacity
The increased fluid system capacity and filtration life provides improved oil cooling and ensures that equipment constantly runs on clean oil. Engine efficiency is increased, providing extended engine life.
Soot Removal
AMSOIL has designed a high-efficiency bypass filter element that is also a soot removal device. AMSOIL Ea Bypass Filters use a synthetic/cellulose sandwiched media. The inner layer of the element is composed of a highly efficient cellulose media covered with a full synthetic media outer layer. These filters remove 39 percent of soot contaminants less than one micron. Soot removal efficiency increases approximately 10 to 14 percent when the EaBP Filter is used in conjunction with a standard full-flow filter.
