Been working on a restoration project, cleaning prepping for paint, in process removed fan belt pully off crank. Was kinda a hard pull but that a long story for a different post. When I first brought tractor home and got her loose and running, had sat for 10 yesrs, front seal leaked a little at first but sealed after running seveal times and getting some oil to it, assumed it was probably a felt or leather seal and just dry. Question is now since I pulled pulley, is that what the seal seals on or is it further in on crank? and if so what are chances that it will still be OK and seal again after reassembly or is it wisest to change seal now since I'm about half there anyways. Opinions. Thanks Rocko.
