I can help you pick out a grease seal, but the number you listed doesn't cross reference with anything we offer.

To pick out a replacement grease seal you will need to measure the diameter of the spindle where the grease seal rides with a digital or dial caliper and then need to measure the hub bore where the current seal rides. With those two dimensions we can pick out the correct seal that you would need.

I attached a link to a page that has all of the grease seals we carry. You will need to select your inner and outer diameter from the filters on the page and the correct seals will be listed.
