Replacing gaskets and oil seals

Lever the seal out with a screwdriver, working carefully to avoid scoring the seal housing.

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.

The cost of new spark plugs can range from as low as $2 to as high as $20 per plug. Cheaper spark plugs are often made of basic materials and may not last as long as more expensive options. On the other hand, high-quality spark plugs are made of premium materials such as platinum or iridium, which can resist wear and corrosion better than cheaper materials.
