Engine block replacement of a 2005-2008 Cub Cadet 1045 Lawn Tractor with a single cylinder Kohler Courage 20hp engine. Replacement blocks should work for any Kohler Courage within the SV470 to SV620 range (15hp-22hp range). I hope you enjoy my successes and failures as I swap out a cracked engine block from this 20hp Kohler Courage single cylinder engine. I did my best to document my mistakes so that someone else might be able to save their Kohler Courage if it's developed a crack. 0:00:00 Into/picking up the Cub Cadet 1045 tractor 0:01:54 First attempt at starting the engine 0:03:25 Second attempt at starting the engine 0:08:00 Third attempt at starting the engine 0:12:51 Fixing the valves and cleaning the carb 0:17:05 She runs and drives! 0:18:45 Inspecting the replacement block 0:20:04 Inspecting the 46" mowing deck 0:20:50 Dismantling the engine 0:28:01 Reassembling the engine 0:33:35 Major set-backs and reassembly 0:41:39 First start after reassembly! 0:43:40 Drive belt orientation 0:52:28 First time mowing! 0:54:20 Governor adjustment- runs perfectly now! 0:59:43 Final cleaning and getting it ready for sale 1:03:33 Outro
