Oil from the bottom of LT1050, Cause?

[cdestuck]

A friend called with a LT1050 and said he noticed oil on his mower deck, oil level was low and when he started engine and engaged the deck, smoke came from between the engine area and deck. He shut it down right away. He called me to take a look at it so I'm heading down soon. So, I'm guessing that perhaps the bottom crank seal has leaked the oil and leaked onto the PTO and caused the smoke.

Do you guys think this assumption is correct or it there something else that could be leaking? So if it is the bottom seal, does the PTO and trans pulley get pulled and seal pulled out and just replaced? And is it much to cleaning the oil off of the PTO. Any other ideas or tips appreciated. Thanks

Assumption are for jumping to when you have no Idea.

If oil is on the mowing deck and not on the mower floor then the lower seal is prime suspect.
If oil is on mower floor ( the bit the engine bolts to ) then a cracked crankcase , blown dip stick tube are 1 & 2
If oil is higher up and coming from the fuel pump then blown head gasket takes the No 1 position.

Or the oil & smoke might not be connected

Look with an open mind. then make your diagnosis
