So if there is any oil is on the carbon seal on the crank as it butts against the lapped surface then its trash and I will need to start over with a new seal? Wish these kits would give some sort of directions.
On the contrary, you MUST oil the lapped surface and the carbon seal with refrigeration oil. What you don't want on there are acids from your skin. They can (supposedly) etch the lapped surface and create a small amount of leakage. Whether that is really a risk of the unit is going to go into service soon after assembly is anyone's guess, but the manufacturers are the ones who say to avoid skin salts and acids getting onto the seal components. You also don't want an particulate matter on those surfaces, so cleanliness is very important, and gloves are a good way to assist in cleanliness.
EDIT: I changed my above post. The LAPPED face of the seal seat faces, and contacts, the carbon seal. I actually am not sure which side of the seal has the lapped face - I was thinking of another seal assembly which has a stepped lapped face, but it ocurred to me there is no reason the RV2 has the lapped face on the stepped side. It could just as easily be on the side with the taper. After cleaning with acetone it should be obvious which face is the lapped one. Hopefully, someone like Wolfgang will chime in here and confirm which face is supposed to be the lapped one. My apologies for possibly giving incorrect information. That was not my intent, and I hoped it hasn't caused any difficulties.
