This translates to a seal that is 70mm outside, 55mm inside that is 9mm thick.

Search for 55x70x9 oil seal. Numerous available online.
Should be able to get it at NAPA or other auto parts store with a knowledgeable staff.

I guess I should have said that it translates to a seal that is 55mm inside, 70mm outside, that is 9mm thick.
That keeps it with the number designation better.

This is where I order my seals. Never had a problem with ordering from them. When you click and pull up the product, in the description it gives nominal A size and a nominal B size for the inside and outside size. This number is sometimes misleading. Always go by the size that you type in for the measurements. This link provided is for a metric size 55 ID...70 OD...9 Thickness... Type oil seal. Hope this helps. They usually have pretty quick shipping which is also reasonably priced.

Hi Beagledog
Do you remember where you got the PTO oil seal?
Mine just started leaking and I need to replace it.
How did you get the old one out?
Any tricks you would like to share?
Thanks

Your local bearing supply house should be able to get you something if you bring the old part in.

Have you replaced the PTO seal on a Satoh Bison? Not sure how to get the seal out.
I tried taking the PTO shaft out and I think that was a mistake. I put it back together and now the shaft wobbles when in gear.

Wish I could help you on this, I don't have any personal experience with this though. I would again recommending calling Valley Power, they are probably the most accessible and knowledgeable source of Satoh parts and repair information.
