My aftermarket seals arrived today.  They are identical to the one we removed, and they are "will fit" parts for Cat 9W7225, so I am assuming the Cat part would be identical also.   There isn't really much room for discrepency on the duo-cone seals because the hub has to fit the seal.  9370 tractor, idler wheel,   Not sure of the Case number,  it's been several days since I looked it up and the  parts man said the number changed and the price doubled when he tried to order it.
