gottahavvitt 0 #1 Posted September 18, 2008 I am thinking about putting a 12HP Kohler in my 1057 but am wondering if it is even possible or plausible? What do you guys think? Share this post Link to post Share on other sites
daemon2525 5 #2 Posted September 18, 2008 Absolutley it will fit. Mine has a 12hp k301 in it. I think that they are Exactly the same size. (as the 10hp) Share this post Link to post Share on other sites
kpinnc 14,641 #3 Posted September 18, 2008 The only difference between a K241 and a K301 of the same era is what's different internally. Bore size, valves, crankshaft, etc... Of course, you'll need to be sure the K301 you plan to use has the same type ignition system as the 241 you already have. Otherwise, there will be some major electrical issues to work out. Not 100% sure you can simply remove all the electrical components from the 241 and just bolt onto the k301, but you SHOULD be able to, providing they are of the same era... BUT, as far as "if it will fit", the answer is yes. Any K301 will fit the tractor. Kevin Share this post Link to post Share on other sites
Kelly 1,033 #4 Posted September 18, 2008 your 1057 is gen. start, and most 12hp are gear start, but that is easily changed, or adapted, make sure they use the same style oil pan, there are 2 diff. one's, one has ear's the other is square, your 1057 has the ears.

gottahavvitt 0 #5 Posted September 19, 2008 OK here's the thing. I have been trying to buy a K301 from a guy on CL for a few days. Would not give me serial numbers or even a price. Wanted me to drive the 40 miles to check out what he has. Well, He finally got me some numbers. It is a K241A NOT a K301. with a serial number of 3116468.Which is what I wanted anyway. Still won't give me a price. Comes without carb or Starter generator. No problem tho because I have the parts off of my other 241. So going by the serial number will I be able to use his motor with my carb and startwer gen? I cannot find a palce to look up the serial number Thanks Joe Share this post Link to post Share on other sites
kpinnc 14,641 #6 Posted September 19, 2008 Joe, take the numbers from your K241, and the numbers he gave you, and compare them on the Kohler Engines webpage.

gottahavvitt 0 #8 Posted September 24, 2008 I made a mistake with the numbers. The spec # is 46560D. I cannot find any of these numbers anywhere. :banghead: Share this post Link to post Share on other sites
Buzz 502 #9 Posted September 24, 2008 I made a mistake with the numbers. The spec # is 46560D. I cannot find any of these numbers anywhere. It's off a Jacobsen. Don't have a clue on whether it will fit your tractor. :banghead: Share this post Link to post Share on other sites
gottahavvitt 0 #10 Posted September 24, 2008 It's off a Jacobsen. Don't have a clue on whether it will fit your tractor. Thanks for the info. Where did you find that information?? Isn't a K241 a K241 other than maybe the oil pan?? Share this post Link to post Share on other sites
