2003 Scag Tiger Cub. Scag STC48A-19KA. Looks like it has a Kawasaki FH601V-AS2 engine. It does still run. I think it lost oil. Put more oil in and it leaks out the top side real bad while running. I didn't look under the bottom side yet. I took off the top covers and the crankshaft has enough play in it that flywheel is rubbing against the magnetos. Are there bearing in these engines or is it only the crank against the aluminum case? What are my options for fixing this? Rebuild? New block? Change engine? Are there other engines will fit without changing out other components? How do I get the flywheel off? I got the big bolt out but I don't see any threaded holes or an easy way to get a puller on there.
