Why would folks look into crankshaft seals first?
It's one of the most labor intensive to fix...

When we are not sure as to the cause of a problem we start by fixing everything we can think of, starting with the cheapest and easiest.

Some likely places for oil to leak that I would check (and fix / replace) first:

Valve cover gasket.
Dipstick cap or shaft seal.
Governor shaft seal.
Oil filter seal.
Oil drainage plug loose or not sealing.

Those are all the easy ones, then there's...
Cylinder head gasket.

And if it's none of those you might be in trouble, about now I might check into the upper or lower crankshaft seal...
It's just that it's not the first thing I would get into fixing.

 

Just had my oil drainage plug fixed and ran it longer to find my oil pan seal is bad as well.

Not sure about yours mine was a mess as well FH641V.

I thought crank or trans seal was out as well but it had just slung it everywhere picked up grease made it look metallic.

My old dealer said they all do it don't worry about it lol

Get it fixed to dangerous to be mowing like that mine almost caught fire when seals went out in full.

 

Its very common for the 2 bolts on the "breather" to loosen up, you have to remove the flywheel to get to them.

That should be removed and cleaned out periodically anyways all kinds of nasty builds up in there.

Actually, Larry, there are three bolts on the breather of that engine. But you are correct the flywheel has to be removed. Best to go ahead and replace the gasket once all of that has been done. This is the most common oil leak on the 23 hp kawi, at least in my experience.

 

Tks y'all I'm awaiting a call from the mechanic I will post once they let me know what it is, if they find it this time

Really! Shows what I know.

 

Update, just called me said a bad upper crankshaft bearing and the crankshaft pulley was frozen!!!

Would it even run with a frozen pulley?

 

Thats what I said, maybe they are talking about it being frozen because they could not get it off, but I dont know why they would need to take it off to change the upper bearing, the girl was reading the ticket, I will have to talk to the mechanic when I got to pick it up later in the week to find out exactly what they did.

 

Ok they replaced the upper and lower seal and the reason for saying the frozen crankshaft pulley is because instead of pulling the whole engine off to change the lower seal they dropped the crankshaft pulley to access it which was frozen on the shaft after never being removed for ten years. Cut 3 hours and did not leak so hopefully that's it.
