To install an oil seal properly, the shaft must be undamaged. This is so the oil seal can do its job properly on the one hand, and to prevent it from being damaged during fitting on the other. In addition, it is very important to lubricate the shaft, the sealing lip and the bore with plenty of grease. This will allow the oil seal to slide more easily over the shaft and prevent dry running after the first rotation. The oil seal may also come into contact with the keyway, thread or other grooves when sliding over the shaft. By taping or covering the shaft at the location of these irregularities with oil-soaked paper, the oil seal can be mounted without damage to the sealing lip.
- Advancements in spark plug technology have further enhanced their utility. Iridium plugs, for instance, offer longer lifespans and improved performance due to their superior conductivity and resistance to wear. This innovation not only reduces maintenance intervals but also contributes to overall engine efficiency and vehicle longevity.

Smear gasket sealant on the mating faces of the pump and the engine. Refit the pump and gasket or gaskets and tighten the fixings.
Heat and attrition are generated by the parts moving against each other. The sealing function can only be ensured if an intentional defined leakage of oil is able to exit for seal lubrication, preventing seal wear and possible failure, while a tight static seal between shaft and sealing lip must be assured when the shaft is stationary.

These seals are designed to fit snugly around the shaft of the machine, preventing oil from leaking out while also keeping dirt, dust, and other contaminants from entering.
