Found this last night. Honda part#91202-357-003 oil seal.
It measures 25x55x10mm. Anyone see any reason why this wouldn't work?

Without a pic it is hard to tell if it's suitable or not.......

Are you actually going to dismantle and rebuild the crank, Doug ???
Did your seals turn out to be bad ???

Not a great pic
Hope this works. I am going to have the crank rebuilt. I'm sure the seals are shot. They are all too loose on the shaft to prevent oil leakage. I think I know what your concern is Rick. Doesn't look as if there are the little tabs on the inside of the seal that allows oil to the bearing, right? Was thinking that perhaps I could modify them and open a few passages where the tabs should be???

Doug, the only problem with that idea is that you'd be cutting the metal and weakening it, especially with the amount of metal you'd have to remove.
I would contact Crooks Suzuki or Suzuki Simon or E.S.B Motorcycles in the UK for any exotic bits like that. You may also want to contact S.E.P. in the UK as well. Those guys were Suzuki's crank rebuilders/warranty depot back in the day and still do work on ALL cranks even now. If they don't have those seals in stock they can probably point you in the right direction.

Rick, I wasn't thinking of cutting into the metal but around the outer inside rim of the seals themselves. Am thinking now I'm all wrong about the purpose of those little tabs????

edit: Upon closer examination of the old seals, I don't think these will work unless they are hollowed out on the outsides like the old ones are and that the tabs are on the inner face. I would have to get very lucky that the new ones are designed the same....Oh well.
