Technical Wheel Seal Cross Ref.

Speedway 912-S18580, anybody know the Cross on this Seal. Thanks

 

I might be mistaken, but I believe that fits a full/mid size GM 11" rotor.
National seal #8871

 

What's the seal fit?

 

Check this thread, see if it has any info for you.

The rotor is 73-93 F-150 but I don't know if the Center Bore of the Seal would be Different since it is going on 64 F-100 Spindle. Running A13 and A2 bearings.

 

#8871 is close it's got the 2" Bore, I need 1.875" x 2.625".

Wonder if this Tranny seal is what Speedway is using? NAPA NOS18580

 

Just updating research, Called Speedway ,They have no Info. on the Seal. Suggested I just order one and Spec. it out. Chased down Diameter and Center Bore of 912-S18580 any body got one laying around that could measure Thickness? And maybe this Elusive seal that a few Threads have can have a Nomenclature of more than one resource.Thanks

 

For Those that keep up with such things, Finally run the 912-S18580 to ground. The Replacement Seal is SKF 18580 so if any of you folks have any Speedway Kits with this Seal might won't to write it down some were.
