How to replace the governor assembly and govenor pin in a single cylinder Kohler Command Pro engine. This is in my 2003 Craftsman LT1000 Lawn tractor with an 18hp Kohler CV492s engine. The engine spontaneously started overrevving and most likely would have self destructed. The problem was that the govenor pin came off of the shaft and there was no speed regulation. I show the steps taken to remove the engine, take off the bottom sump cover and replace the govenor gear and pin. This is a DIY project thay could save hundreds of repair dollars and will restore the engine to working condition. The failure of the govenor mechanism could cause serious engine damage if the engine is operated in this condition. My 18 year old tractor was fixed with a few hours of work and inexpensive parts.
