Manual Extract FRONT OIL SEAL

Check the front oil seal carefully to determine whether or not it is damaged.
If it has been damaged, replace it.
If the oil seal is in good condition and shows no sign of .cuts or excessive wear, it should serve satisfactorily through another period of operation provided the contact surface on the fan drive pulley is in good condition.

Examine the surface very carefully since any roughness or scratches of any kind will cause an oil leak and eventually will damage the seal.
If the surface is damaged and the pulley is otherwise satisfactory, build up the damaged surface and the contact area by brazing. Then turn the surface again to the specified size and polish it very carefully.

Another method of salvaging the fan drive pulley hub is to turn the surface down in diameter and shrink on a steel sleeve. Finish the outside diameter to the original specification and carefully polish it.
If this is done, make certain there are no rough edges left to damage the seal during assembly. If the belt surfaces in the pulley are damaged, replace the pulley without question.
