SOURCE: 2000 yz125 - Water pump seal change
The two seals in the diagram below are separated by the casing they fit into. The impeller is threaded to screw onto the impeller shaft. I think you already knew that by your "holding the tire" note. The center casing does not get split. The right casing does remove then a wrench is used on the shaft as the impeller unscrews counter clockwise. It is risky to "Lock the wheel" because the gear on the impeller is very thin and can break.
A “very helpful” rating on this answer? Thanks!

hi,you are quite correct,it will be the seal behind the impellor,kawasaki and suzuki are famous for it,simply undo the nut holding the impeller on,remove the impeller,you will have to pry the seal out,when replacing the seal use a "loctite type"sealing compound to reseat the seal,hope thjis helps...cheers
