Slacken the alternator or dynamo adjuster and pivot bolts, push the unit inwards and ease off the drive belt. Remove the belt completely.
Sealing of lip type seal is normally a result of an interference fit between the flexible sealing element, usually augmented by spring pressure and a shaft. Fluid retention is based on the precise amount of lip contact pressure. In most lip seals, increased fluid pressure in the sealed area causes lip contact pressure on the shaft to increase.

The reasons for the birth of this new generation of seals is that integrated oil seals reduce the manufacturing time of series production engines. Therefore, significant time savings are achievable when replacing the radial crankshaft seals.
Please see the following for the types of sealing devices for bearings.

An oil seal, also known as crankshaft retainer, is a small device, but essential to ensure the proper engine operation. It plays a key role in all moving parts of an engine, acting as a physical barrier. This mechanical seal fulfils the dual purpose of sealing a rotary shaft to maintain the necessary lubrication (avoiding leaks) and preventing other foreign matter from contaminating shafts and bearings in the rotary shaft equipment.


14x24x6 oil seal. They are designed to withstand high temperatures and pressures, as well as the friction and heat generated by rotating shafts.
