Hey guys. As I posted a few days ago, I am slowly doing an in frame overhaul on my TO 35 gas burner. I had some oil pump issues which you guys helped with, and with finding a good side over, that issue is all resolved. I have the pump and new main bearing back in. Also have the center main bearing replaced. My current questions regard the rear main and seal. (I am working without a manual since mine was recently lost or misplaced during a move.).....I want to put a new rear main bearing in, but am unsure what I am getting into with the seal. My gasket set has a large round seal which I know can only be installed with the tractor broken apart, which will not happen now. In looking up at the main, it appears to have a straight seal on each side. Is this correct? And can I simply replace these as I put the main cap back up ? I have also removed the 2 small bolts that point toward the flywheel, but not sure I understand what these are for....I guess the bottom line is that I want to have all new main bearings in it, but not at the risk of creating a back main leak. I would rather leave the old bearing in place than to create a new problem. Seeking all input and advice,lol Thanks, Ron
