A friend wonders if he can replace a K301 (JD 212) with a K341 (Wheel Horse).
Is that a big problem... Thanks
 
Bet this one gets involved. Simple answer would be yes. NOW....... there are people on here who really know but you are going to need to measure the out put shaft from the engine. If it has a standard oil pan or a low profile. Do the wire plugs for the charging system match up. A really good old fashion mower parts store would have referring type books and could cross everything. Just MHO. The guys on here can tell you what to do but thus is just a starter list. You can also download the Kholer service book for these engines from their web site. Has like 135 pages of information. If you dig back half a dozen pages on this listing you will find some guys have posted a short cut to it
 
To tell without actually trying you need to find a Kohler K series PARTS book and track down the nuances of each of the motor spec numbers. Compare the differences and see of it's anything you can live with or overcome. The spec number will give you information about the crank diameter, length and center line height, it also identifies what starting and charging systems you have, the air cleaner fitment, the dip stick placement, fuel pump or not, gas tank or not and oil pan. for some units like the Cub Cadets it's a little harder because you have to keep the crank height the same or modify the tractor frame as the second generation narrow frame tractors were first set up for the crank height of a normal k141-181 series engine and for a narrow frame Cub Cadet you have to have the starter generator as the engines with the starter/ring gears and the internal alternator are to wide to fit between the frame rails. I'm not familiar with the engine fitment on the JD 212 and I'm also thinking the K341 is a different series of engine, where the 241 and 301 are the same external dimensions the 341 was a little taller, so you'll also have to make sure the engine will fit under the hood if that's important to you.
 
The Wheel Horse will more than likely have a tall two quart oil pan and a long dipper on the rod cap, the JD?? but the crankshaft height needs to be the same as well as the pto fit on the crank. I stuck a tall pan 10 hsp. kohler out of Simplicity in a JD 110 that had an eight horse in it. It was a lot of work, rework frame, make a muffler and more alterations. It turned out good but I wouldn't do it again. Had to cut some off the end of the crank too.

Another possible problem is the dipstick and tube placement, been there done that, no fun.
 
Thanks Jeffcat and others, for replys. I will just tell my friend, NO! Cannot do it. Since he
calls me when things don't go right. heehee
 
If it was for one of my tractors, I would do it. Between my and my grandsons we probably have all the parts needed to do it. For someone else, no it can't be done.
