The function of the skeleton oil seal is generally to isolate the parts that need to be lubricated in the transmission parts from the output parts, so as not to allow the leakage of lubricating oil. It is usually used for rotating shafts and is a kind of rotating shaft lip seal. The skeleton is like the steel bars in the concrete member, which acts as a reinforcement and enables the oil seal to maintain its shape and tension. Internal and external exposed skeleton oil seal. The skeleton oil seal is made of high-quality nitrile rubber and steel plate, with stable quality and long service life.

- The design of the piston oil seal is quite remarkable. It consists of a flexible rubber or synthetic material that forms a tight seal around the piston rod. The seal is designed to maintain its shape and effectiveness even under extreme pressure and temperature conditions. The material used in its construction is carefully chosen to withstand the harsh environment within the engine while maintaining its flexibility and resilience.

Improper
Put the jack and wooden spacer under the sump and raise the engine just enough to free the supports.
The main causes of external lubricant leakage from pumping systems, hydraulic machines, gearcases and sumps are the wrong selection, improper application, poor installation and inadequate maintenance practices that are applied to sealing systems.
