massive oil leak

overnight my super mini z kawasaki engine leaked a lot of oil on the floor.
seems to be dripping from the clutch, but I know it is coming from higher up.
How can I determine where the problem is?

You know things flow downstream. I would clean the units thoroughly of all grease and crime.Top to bottom. If it's really nasty some Gunk or other engine cleaner would be good. I would not use a high pressure washer due to the electronics. To make things easier I would drop the clutch. This will expose the lower seal better. Replace the oil and see if anything shows up. I place newspaper under the machine to catch any leaking. If the oil came out while sitting I would focus on the lower seal and sump gasket. If it's pumped out when running check everywhere. since you're under the machine removing the clutch try wiggling the crankshaft. If your lower bearing are shot you'll feel it moving back and forth and that would blow your seal.
Good luck,

Thanks for the quick reply.
This happened while the machine sat stopped.
I will do that.

lower seal leaks

I have removed the clutch and the pulley for the drive belt and the leak is coming from the lower seal.
Can I remove it and replace it without removing the engine (engine still mounted on mower) or do I have to remove the engine to replace this seal?
Thanks

Believe it or not you are having a good day. Yes you can replace without removing the engine. Remove the old seal after you get a new one in your hand. Make sure the crank is clean and well lub'd when you install the new seal. take your time tapping it in place.

I got the seal off and bought the new one today.
I am hoping to have the engine running tomorrow (work until 7 pm today).
What is the best way to tap the seal to place?
I thought of using a piece of pipe that can go around the shaft.

Perfect, as long as the size is right. The tool that puts the seal in is not much different than what you hope to use. Just be sure to oil the shaft and your pipe is only hitting the metal on the seal.
