Installation Position and Core Function

1. Installed in the base of the fuel water separator and inside the engine oil filter base, serving as the central positioning and conductive connector for the filter element;

2. Connects the internal oil passages of the base with the central passage of the filter element, ensuring unidirectional flow of high-pressure fuel/oil;

3. Works with the sealing ring to achieve leak-proof sealing, resisting oil pressure impacts under heavy-load conditions;

4. Precisely limits the positioning of the filter element to prevent eccentric installation, oil bypass, and filtration failure.

Installation & Maintenance: K19/K38/K50-Specific Best Practices

Failure Replacement Scenarios:
1. Thread slippage of connectors, step wear, oil leakage or diesel seepage after filter installation;

 

2. Internal oil passage blockage or corrosion, insufficient fuel / engine oil flow, resulting in reduced engine power;

 

3.Complete engine overhaul, replacement of filter base, simultaneous replacement of oil-water separator filter (4328043);

 

4.Frequent filter loosening and abnormal base oil pressure alarm.
