How to Deal With the Leakage for the Oil Filter of Diesel Generator Set

Aug. 23, 2021

The main function of the diesel generator oil filter is to filter out various harmful impurities in the oil, prevent the mating surface of the parts from wearing and prolong its service life, but sometimes users find that the oil filter leak oil. In this article, generator manufacturer, Dingbo Power recommended that the user should carefully inspect and repair in accordance with the following three aspects when the oil filer leaking.


What Should We Do If the Oil Filter of the Diesel Generator Set Leak


1. First, check whether there is an oil leak on the outside Pay special attention to whether the oil seals at the front and rear ends of the crankshaft are leaking. The front end of the crankshaft oil seal is broken, damaged, aging, or the contact surface of the crankshaft pulley and the oil seal is worn, which will cause oil leakage at the front end of the crankshaft. The oil seal at the rear end of the crankshaft is broken and damaged, or the oil return hole of the rear main bearing cap is too small, and the oil return is blocked, which may cause oil leakage at the rear end of the crankshaft. In addition, pay attention to whether the oil seal at the rear end of the camshaft is leaking. The oil seal should be replaced in time if the oil seal is aging or ruptured. In addition, it is necessary to check whether there is any leakage in the parts of the engine lubrication system.


2. If the oil leaks at the front and rear oil seals Even the front and rear cylinder head covers, front and rear valve lifter chambers, oil filters, oil pan gaskets and many other places where organic oil seeps, but no obvious oil leaks are found, the crankcase ventilation device should be checked and the crankshaft should be cleaned. The ventilation duct of the tank, especially to check whether the PCV valve does not work poorly due to carbon deposits and glue sticking. If the crankcase is poorly ventilated, the pressure in the crankcase will increase, which will cause multiple oil leakage.


3. If the oil filter and some oil pipeline joints are still leaking after being tightened, check whether the oil pressure is too high and the oil pressure limiting valve is not working properly.


When encountering leakage of the oil filter, the user can perform maintenance according to the above three conditions.
