Actually the Courage has been redesigned with different internal parts and is now called the 5400 series. Still a bucket style block. And the twin is the 7000 series.Courage is no more. Kohler had continuing issue with it, poor design. My wife has one on her zero turn (CC RZT) and it an oil burner. Not impressed. In fact I use it to burn my waste oil. Very efficient at that...lol
1 1/4 or 1 1/8.Socket size for the flywheel on my 22hp B&S v twin. My 1inch socket was too small.
Overall, I'm not overly impressed with the new Kohler engines. Now my old school K241 is a solid engine and it's cast iron (except the head), not pot metal (pressurized die cast mystery metal)...Actually the Courage has been redesigned with different internal parts and is now called the 5400 series.
