Kohler block size question

I have here a '74ish Ford LGT tractor with what I believe is a JD 14hp K series that was swapped in by a PO, engine is all black but it had a JD air cleaner cover on it which recommends a JD part # for the filter... problem is there is no pto on it, and the Ford pto has a larger bolt pattern so those dont fit... output end of the crankshaft is also larger on the Fords, so the question is would this be the differance between a narrow block and wide block K series?
I have 6 of these old Ks here, 10 to 16hp, but only one is differant, and I'd like to find a pto for it but I need to know why its differant and what tractors might have the same block. tia
 
Tractors of that era I know of that used the K Kohler were Ford, JD, Cub cadet, Ariens, Allis Chalmers and there were probly more. Each used a little different spec motor.
The Ford was the only one I can think of that used the "narrow" block. The pan was part of the frame. I was not aware that the clutch bolt patern was different in the blocks. You may need to get a JD clutch to make it work.
 
I agree. The blocks would be the same but JD specified a one-inch PTO end on the crankshaft. You would need the John Deere PTO setup.

Cub Cadet engines used the oil pan that bolted to the frame as well as John Deere.
 
If you start looking at Kohler parts catalogs, there were a lot of available differences in K series Kohler engines. there were at least 2 different size blocks for most bore sizes, several different oil pans, different diameter/length crankshafts, different starting equipment, etc.

If you want to know what the engine came out of, I think you can go to Kohlerplus.com with your model and spec. number and it will tell you at least the unit manufacturer the engine was sold to.
 
Thx guys, I cant be sure which tins belong to what, there was a couple big boxes of parts came with this tractor when I bought it over a year ago, I would guess he pieced it together from at least 3 differant tractors, the installed motor is black but has the blue Ford tins on it, and the green air cleaner. It was cheap and it runs quite good, little white smoke for a few seconds after its been parked for an extended time but its proven to be a decent tractor over the last year.

neway... the motor does have a 1" output shaft, the Ford engines have 1 1/8", the top two bolts for the pto magnet bracket are 3 1/4 centered, the Ford pto bracket reqiures 3 7/8 centered... I would have thought the wider bolt spacing would be the wider block? No?
 
Hey Jeffcat,
Try to pay attention this time. LOL


At no time did INGERSOLL RAND EVER EVER EVER EVER EVER make a lawn or garden tractor. It did not happen and if you can find one, then I will pay you ONE THOUSAND DOLLARS in hard USA cash for it.

The company WAS Ingersoll Equipment Company and it was not connected to Ingersoll-Rand in any way, shape or form

Please write that down on a sticky note and paste it to your monitor. ROFL
 
Yes Jeff. there is a problem.

The problem is that you fail to realize that you don't own an Ingersoll-Rand garden tractor because that company never made one.

However, it may be that you do own an Ingersoll garden tractor that was made by Ingersoll Equipment Company. Perhaps if you took a moment to read the ID tag on the side of the frame, you might come to that realization.
