Replacement for 904-7904 Cummins Crankcase Ventilation Filter 

Product Details

The crankcase is circulated by a specific ventilation pipeline to ensure the pressure inside the crankcase and exhaust gas inside the crankcase. If the ventilation air filter is blocked, it will cause poor circulation, which will lead to high pressure inside the crankcase, damage the seals inside the engine, and may cause oil leakage, gas leakage, and poor sealing. At the same time, the exhaust gas that cannot be discharged will also cause corrosion to the engine body, Accelerate the deterioration of the engine oil. All these will show up slowly, so when doing maintenance, do not just change the engine oil, but also check the relevant components

Product features

1.The proper viscosity and good viscosity temperature performance can ensure that the hydraulic components can be well lubricated, cooled and sealed when the working pressure and temperature change.

2.Good extreme pressure and anti-wear performance to ensure that the friction pairs in oil pump, hydraulic motor, control valve and oil cylinder can be lubricated normally under high pressure, high speed and harsh conditions, so as to reduce wear.

3.Excellent oxidation stability, hydrolysis stability and thermal stability to resist the influence or action of air, water, high temperature, high pressure and other factors, so that it is not easy to age and deteriorate, and prolong its service life.
