I had everything ready, so I figured on about 30min. Warmed it up, slid a drain pan under then removed the drivers side drain plug. When I removed the off plug, it had a lot of resistance to it:scratchchin:. No metal came off on the threads so I pulled the old filter, spun on a new one then replaced the plugs. Yep, the off one was stripped:jaded:. Now I know what y'all are thinking, that I went Gorilla on them, but i know better and only "snug 'em".
So I had to run into town and get a self tapping over sized-plug. It was impossible to start by hand, so I used the air ratchet to get it going, then finished by hand. The new plug has a smaller removable piggyback bolt inside of it so I don't ever have to take the self tapping part out of the pan(good). But, the second bolt hangs down a lot further than a stock one..about an inch(bad)....so I really need to think about making that belly up pan this winter.
I'm really wonder why a aluminium oil pan is used by Kioti(and others). Steel would probably be cheaper and a lot tougher. At the very least the aluminium one should have a steel insert for the drain plug...jmho.
