Oil leak under Snapper RER after belt break

[hiltonheadSNAPPER]

Hi guys. New here with a problem. My 2006 Snapper RER series 23 was a craigslist find that had a rusted out mower deck. I replaced the mower deck from Clist, put new driven disc on, and started mowing. The belt began to smoke and after about 15 minutes of mowing, the new belt I had put on disintegrated into shreds. When I drove it into my gargage to park it, a pool of oil formed under the drivers right rear wheel just off center and near the transmission (looks like about 6-8 ounces). What do you guys think this is? Crankcase seal or something worse. I checked oil level and its only down about halfway between full and add on the stick (it was at the FULL mark). I also added gear oil to the transmission and when I removed one of the plugs it probably is leaking a little from that, but a 6-8oz leak? Help anyone?

http://www.snapper.com/us/en/support/manuals/results?NTT=7800104 Read through operators manual thoroughly, transmission uses grease not gear oil, you need to locate engine oil leak. Also check idler pulley bearings, on deck, for being worn out by removing idlers.

Yes thanks I realized I needed Snapper 00 special grease. I ordered new grease plugs so I can change out the gear oil to the grease. I am probably going to pull the motor so I can thoroughly inspect it. Pretty much gotta be blown motor or blown crankcase seal. I can't seem to find the source of the dripping yet....the drive disc feels dry when I feel above the clutch/driven disc so Im worried Ive ruined the motor. Yes the smaller pulley had bad bearings and Ive already swapped it out. But I may have killed my motor in the process. I need to diagnose the issue, and if its the motor, I am determined to replace the motor if needed. Kind of a matter of principle now with me....I dont want to get rid of the mower now, I kind of bonded with it. LOL
