Reasons for Oil Seal Leakage of Agricultural Machinery

Oil Seal is an important part of various agricultural machinery and equipment and is widely used. There are various oil seals installed on tractors, agricultural transporters, rice and wheat combine harvesters and other agricultural machinery, which can effectively prevent the leakage of lubricating oil and hydraulic oil and prevent dust and dirt from entering the machine.

The performance and quality of oil seals directly affect the reliability of various agricultural machinery and equipment. The life span of oil seals is 1 year in the long term, but only a few months or even 3-5 days in the short term. If the poor seal leads to oil leakage and scrapping, it will seriously affect the efficiency of various agricultural machinery and equipment, which will not only increase oil consumption and production cost, but also pollute the environment.

Agricultural Machine Oil Seal

The following are the causes of oil leakage of agricultural machinery oil seal shared by the automotive oil seal supplier：

1、New or overhauled agricultural machinery does not strictly follow the technical procedures of grinding operation and maintenance after break-in, so that the metal chips ground out enter the oil seal from inside the body, causing abrasive wear and early oil seal damage.

2、When installing the Agricultural Machine Oil Seal, no attention is paid to cleanliness, impurities and dust enter the oil seal, causing accidental wear of the shaft seal.

3、When installing, the operator knows that the crankshaft has obvious scratches and burrs, but still puts the oil seal into the machine, causing oil seal strain; or the seal and crankshaft are not sealed enough, causing oil seal leakage.

4、The oil seal with obvious defects, aging and cracks are installed on the machine, causing oil leakage from the oil seal.

5、Improper operation during assembly causes distortion and deformation of the oil seal, or even causes the oil seal self-tightening spring to fall off and be lost, resulting in oil leakage.

6、Self-tightening spring of oil seal is not flexible enough and the sealing performance is poor, resulting in oil leakage.

7、Agricultural machinery often over-speed operation, so that the rotation axis of oil seal exceeds the adaptability of oil seal, resulting in oil leakage of oil seal.

8、Crankshaft oil seal installation position is not correct. Such as small tractor drive shaft rack self-tightening oil seal and skeleton rubber oil seal position opposite, or rack self-tightening oil seal opening installed in reverse, resulting in oil leakage; crankshaft oil seal installation is incorrect, resulting in oil seal centerline and shaft centerline do not coincide, resulting in oil leakage.
