Oil Leak

I"ve got a serious oil leak. I just put on a new radiator for my 641 Workmaster and discovered that it is leaking oil. It looks like it is coming from the bottom pulley in front. It runs down the sloping piece right below the pulley. I can"t see that it is coming from under the timing gear cover, but it is somewhere in that area. Can anyone tell me if there is an oil seal behind that bottom pulley and if so, what is it called and a part number to order one. Thanks.

There is several places it can be coming from.
Crankshaft front seal.
Governor seal on the side.
Governor cover gasket.
Timing gear cover gasket.

If it is leaking as bad as you say you can take the belt and front pully off. Reinstall the bolts with out the pully and run it for a few seconds to see where it is leaking.

I found the leak. It is from the rubber seal immediately behind the pulley. I called a dealer and he said he had the seal ($4) and the timing gear comver gasket (40 cents) but I didn't want to risk messing up the governor by taking the timing gear cover off. I don't know much about mechanics but it seemed a big task to me. It still leaks, but I guess a quart of oil three times a month (when I mow my yard) is not a high price to pay. I'll just let her leak.

Thanks for the suggstions. I will take the radiator out again, remove the pulley and reinstall bolts to see if I can spot where the leak is coming from.
