k341 on a 100?

[Stitch]

For a while I've been looking for an old style Kohler to rebuild for two reasons. 1. It'll be fun and 2.So I have something ready to go if and when the 10 horse on my 100 dies.


I have a friend who has a k341 out of a John Deere (216 I think) that runs but needs redone. He said I could just have it if I want it.

Aside from the mounts, what would need to be changed if I were to ever try this? Would it be a complete transformation?

Just wondering because he wants the motor out of his shed, but if it wouldn't be possible for me to use it, I don't want it.

i need someone to correct me if im wrong, but i think i k341 and the k241 are similar blocks. i think you would have to change the flywheel, shroud, charging system, and the bearing plate from the k241 would have to go on the k341. you would also need the oil pan from the k241 and install it on the k341. the 100 is a narrow frame and uses the smaller flywheel. the 147, like the machine i have in my garage(my own project tractor) is the only one that used the large flywheel. the 147 is a moddified narrow frame and is the only narrow frame that was modified to fit the larger flywheel.

the only concern i would have is the small flywheel adaquate to cool the larger 16hp engine? im not sure about that.

as far as fitting, i think everything would fit just fine, so long as you changed to the small flywheel, shroud, and flywheel screen, cub charging/starting system, and oil pan(i think the deere's are different).

dont qoute me on this, im fairly certain that information i have provided is correct, im just not positive about it.

If it were mine I would not use the smaller flywheel on a K341. Unless the block is also an "A" (as in K341A, etc) it would need to be modified to fit in the frame, and that may or may not be possible, depending on the casting.

Get the engine from him, sell it to someone who needs it, and use the $$$ to buy a rebuildable K241 or K301 that'll fit with no mods.

I know of the K301's, but don't know what the letters at the end mean. Is a K301S a good choice?

Since we are on the topic of engines, what does the ending of the K301AS stand for? I knew there were different types of the same block castings, but have had no idea as to how vast it is.

This is what I'm wondering. Wanna make sure I'm getting the correct K301.

A = special oil pan
Q = 'quiet' series
S = electric start

If you want the 'correct' engine, get one that was originally in a Cub Cadet.

what is the difference between a cub cadet kohler and a john deere kohler. i have a k301 in my 112 and a k301 im rebuilding for my 147. they look identical. as far as tractors go, im going to keep both and hopefully do 2 full restorations, eventually. to have 2 really nice garden tractors from 2 different manufactures will be really cool. two of the best machines ever built

I think what Matt is saying is that if you get a complete engine you will want one from a Cub Cadet...

CC & JD Kohler engine blocks are basically the same, however the two use (in most cases) different size crank shafts, different oil pans, carburetors, PTO's, and in some cases different tins.

If you are starting with a naked engine block you will probably be alright. If you buy a complete engine from a different brand, you will most likely be buying the correct crank, oil pan and other parts to make the engine work in your Cub.

If you're buying an engine to rebuild it's kinda dumb to buy one from the wrong brand tractor, you'll end up with way more than twice the money in this engine before you're finished.

I am going to rebuild the motor and then use Cub parts to complete it. I will probably get the K301S, but I also have a guy that wants to sell me a K301 I, anyone heard of that one?
