It should be noted that Dave found a supplier that provided seals that met HIS requirements THEN manufactured the tool to install
them.
The tool may or may not work with Chicago Rawhide / SKF or seals made by other manufacturers.

Rob,
I haven't found an SKF seal that passes the 1/4" test, and I'm beginning to feel that it's a fool's errand trying to find one.
Would I be off-base assuming that one could measure the clearance of the rubber seal and simply add the difference that it's short to the spec for how proud the seal sits? That is, if instead of .250" clearance under the rubber there's only .220" could I add the .030" difference to the spec'd .025" to .045" proud seal set? ie, set the seal .055" to .075" proud?
Is this simply a measure the seal and modify the depth of set situation? That would make my life simpler and piss off far fewer auto parts people!
Thanks.
Richard
