I bought this Kohler K341 16 hp the other day to install in my Cub 149. The Cub currently has a K301 12 hp because the original K321 14 hp needs a lot of machine work before it can run again. The modification for the 16 hp can mostly be done by myself other then the turning of the crank which I have a friend who can do this for me. These modifications will be considerably less expensive then rebuilding the 14 hp motor while giving the benefit of a more powerful motor.
The gray line indicates the material that will need to be removed from the engine block.
What would need to be done to a wide base Kohler K341 to make it fit between a Cub Cadet 149 frame.
1. Cutting off the wide base tabs from the engine block.
2. Tap the factory holes in the blocl for the Cub oil pan.
3. Modify the fan shroud by removing the start bump out. This needs to be done to also fit between the frame.
4. Have the pto end of the crankshaft turned down for the starter/generator pulley.
