Pulled the engine on the 1811 for cleaning and new seal behind flywheel.
Power washed everything put it back together and cut grass for about an hour.
As i was finishing cutting the motor bogged down and a puff of smoke came from the front of the engine and the engine died.
Made a oil mess from the flywheel side of a recently cleaned mower.

Engine starts and runs fine and surprisingly the engine is not low on oil which had been changed when I put the tractor back together.

One of the pulleys is bound up or seized I believe but haven't got a chance to look at it further.

I feel the new flywheel side oil leak is the result of the engine working against a pulley going bad that it ran so hot that it ruined the new crankshaft seal.

The engine starts and runs fine and there was no obvious low level of oil on the dipstick but what did come out sure did make a mess.

Anyway ,does it sound plausible that a pulley going bad and eventually seizing could cause the engine to run so hot it could destroy the crankshaft seal?
Thanks.
