Examine the crankshaft where the seal edge sits.
If there is a groove in the crank...you might have trouble getting a new seal to do its job.
I have had good luck with multi-edge seals in this type of situation (a seal with more than one sealing ring).
They can be of the same depth...but have more edges to seat against the crank.
Also...some of them have an outward facing dust shield (to keep dust and grime out so that it does not "grind" the crank).
Hope this helps.
