Choosing Quality Auto Parts Oil Seals:
The primary function of a radial oil seal is to create a tight seal between the rotating shaft and the stationary housing of the machine. This seal is achieved through the use of a flexible rubber or elastomer lip that is pressed against the shaft as it rotates. The lip creates a barrier that prevents oil from escaping, while also allowing the shaft to rotate smoothly without any friction or wear.Clean sediment out of the sump with petrol and a stiff brush . Dry with a lint-free cloth.
The cover is fixed by nuts or bolts on top, or by screws round the edge. Loosen them all and remove them with their washers. If there are several oil-sealing washers under each fixing, note their order.
