I have a John Deere 140 H3 with a Kohler 14 hp engine. The engines runs, but its over 30 years old. For implements I have 54" blade, grader blade, belly mower, 3 point hitch, 33" Roto tiller, box blade, disc blade and plow. Woooo"s.
I said all this to say, "How much is it worth?"
and with all the implements I would like to use this tractor for more then just cutting grass.
So, is there a new model of Kohler engine that has more horse power and will bolt up to what I have, or will I have to have alot of fab work done.

All info will be helpful, Thank you.

A few years ago I dropped a 18hp Briggs Vangard V-Twin in a Deere 140. Took a little doing, but not impossible. Works great. I have a complete written description of the project. Drop me an email, and I'll send you a copy. crrtptch@pathwaynet.com

Cost was very close to the cost of replacing the old 1 cylinder Kohler. With the new engine, you get 2 cylinders, pressureized & filtered oil, etc. Much updated engine.

I thought a 20hp twin ohv Kohler would be great in one. Have a big wallet when you go buy one thought. They should bolt right in. Why not overhaul your 321. I have a H3 140, I rebuilt the 321 2 years ago. I use mine really heavy in the winter with a 54" blade, spring doing some plowing and discing, and in the fall doing the same. It's my working tractor. I have a good collection of Simplicity and Allis-Chalmers tractors and equipment that I still use also. If you can't overhaul it yourself or can't find someone reasonable to do it let me know. You could ship it to me and I'll overhaul it.

As for Steve, what are you doing wrong to throw 3 rods?

I posted about this on the Johnny popper board and it was explained to me that the larger K series Kohlers such as my K321 had a nasty habit of having the block distort. This happens with age and hard use. Apparently the distortion happens in the area were the cylinder becomes part of the crankcase and this throws the cylinder out of exact 90 degree alignment with the crankshaft. This effect in turn causes the rod to thrust hard on one side of the crank journal. Subsequent side stress and heat cause the rod to seize on the journal. This last time the engine had less than 3 hours running on it with a new piston and rod.
The first overhaul was due to the engine smoking. it got a new rod then, and the second time a new rod and crank polish. The 3rd time a new piston and rod. F-I-T explained all this and it makes sense. The v-6 doesn't make a lot of sense, but I'm still thinking about it.

Northern Hydraulics lists a 17 horse Kohler for direct replacement in the 140 and 316. I'm sure there are better prices out there though. Be sitting down. I just threw the rod (again 3rd one) in my own 140 w/ 14 horse Kohler K-321. I'm somewhat looking at a spare fuel injected Chevy 2.8 V6 engine I have sitting in the polebarn. A little creative gearing, and this engine wouldn't need to run much faster than idle. I'm not dumping much more money in this 140.

I wonder what you're doing wrong. I've owned a 140 for since it was new in '74 and just now have replaced the piston and rod after thousands of hard hours. HARD hours. I look forward to putting another thousand on it. I don't think more horsepower from a bigger stupid engine is a good idea for the hydro which was only rated for 14.

Just be sure the alignments are right and you should be fine. The reason my engine did not break the original rod is the rod wore in as the engine distorted so no stress was produced, everything got old together. stick a new piston and rod in without correcting the bore/crank relationship and your asking for it. If I had known about this from the start, I probably wouldn't have broken the first rod. I'm just not going to spend another 2 years trying to find another block and crank, nore am I going to spend $1,300 on a new engine.
