Ok. I will tape this one out with a small socket then. There is a rubber gasket in the parts manual, or a little rubber washer the diagram shows that goes below the o-ring on the drive shaft somewhere?? My Mark 10 did not have it in there so someone was in there and and never replaced it apparently. It is called slinger gasket or something like that. I ordered one…does that just go on the driveshaft to seal the water pump cartridge do you know or seal around the driveshaft where it comes through the housing above the cartridge? I can’t think of anything else it would do.
