After cutting a field for 2 hours or so I pulled back in the shop and noticed a steady drip every half second or so. I split the tractor and ordered a new rear main. Mine has a one piece that presses in the rear motor plate. It then has a no-ring that goes around the backside of the rear main to seal the block and oil pan. Anyway, put it back together and pulled it out. Within 5 mins it was leaking the same as before. It's dripping out of the inspection hole in the bottom of the bellhousing. It's not the transmission leaking because I can see it. I split the tractor again and pulled the flywheel. Seal looks fine and it's definitely leaking. Has anyone gotten a bad seal or have any advice. I installed the new wear sleeve so I know it's the right size. Thanks in advanced.
