Nitrile is the most widely used rubber (elastomer) and it’s recommended as the best for almost all standard applications. This is solely due to the fact that nitrile has some intrinsic properties, such as low cost and compatibility with most environments. Some of the general applications of nitrile are non-latex gloves, automotive transmission belts, footwear, gaskets, synthetic leather, hoses, o-rings, and oil seals.
Some gaskets are in two or three pieces dove-tailed together. Make sure the pieces join up properly.
Unscrew the pulley bolt anticlockwise with a socket and bar. Start it turning with a sharp blow on the bar.
Remove the pump fixing nuts or bolts. Pull the pump and gasket or gaskets off the engine.
Scrape off all the traces of dirt and old gasket from the engine and sump flanges with a paint scraper.
