  • Raise the engine jack below a wooden spacer to protect the sump.
  • An oil seal normally consists of three basic components: the sealing element, the metal case and the spring. The purpose of the sealing element is to stop the fluid from leaking between the shaft and housing. The metal case will give rigidity and strength to the seal while it is being held in the bore or recessed groove. The garter spring ensures constant pressure and maintains the radial force to the shaft, flattening the sealing edge to a defined width. The garter spring maintains the radial force exerted by the sealing lip around the shaft surface. All materials must be selected depending on the environment in which the oil seal will function.

  • The spark plug in a diesel engine is designed to provide an additional source of heat to help ignite the fuel. When the engine is cold or under heavy load, the spark plug produces a spark that ignites the fuel, ensuring that the combustion process is initiated. This is crucial for the efficient operation of the engine and for ensuring that it runs smoothly and reliably.
  • In addition to these standardised types, the following special types are also available:
