27 HP Kohler direct swap
Kohler P/N CH740-3002 is a direct swap using your original exhaust. Otherwise exhaust P/N is 2478610s.
Wires: on the engine connect white & green, blue goes from starter to chasis blue, yellow to chasis yellow, chasis white to starter, fused red to starter pos, purple to starter pos.
What I did for wiring was look at the chasis wiring and copied the hook ups when re-connecting new engine. This also allows for the low oil sensor system that is installed to work.
I also installed a new hour meter with my new engine, chasis black is ground, yellow is hot and the factory chasis harness had them already there, just plug & play for hr meter.
Pretty easy, hardest thing was the exhaust.
