I'm still considering a newer engine but if i can find a replacement k301 i'd rather do that. I see SEARS sells short blocks. And they are priced pretty damn well. Anyone ever try to buy something like this from sears? Thanks for the help Toby [Reply]   [No Email]

As mentioned in other posts you'll be lucky to find a short block from a dealer for less than a $1000. A decent block and a rebuild kit with the machine shop work might run you $300 if you take your time. Here's a replacement block for $50. http://www.ebay.com/itm/Kohler-K301AS-engine-block-john-deere-212-/181073135212?pt=LH_DefaultDomain_0&hash=item2a28ccc66c A machine shop can turn your crank up to .020 under and you can order a rebuild kit with a rod to fit and the .030 over sized piston.   [Reply]  [No Email]

You would need the spec number off the old block. I bought a Kohler short block for the 321 engine. It was off a JD140 tractor and in 1981 it was $300.00. I bought it in Baltimore from a Kohler dealer. Hal   [Reply]  [No Email]

So it's not a matter of how much the bore is off but more less the large hunk missing   [Reply]  [No Email]

They should be the one to examine the block and tell you whether it is salvageable or not. If the broken rod scored the cylinder wall too deeply, then boring it oversize may not be possible but perhaps installing a sleeve will be and then you will be back to a stock bore.   [Reply]  [No Email]

So why would you want to put that kind of money into it? IMO, a wiser move would be to find the SPEC number of your engine and determine from that as to what makes your engine unique for use in a Sears. Things such as oil pans, choice of starter, charging system amperage and most importantly....the diameter and length of the output shaft of the crank. With that knowledge, I would then go searching for either a K-301 or a K-321 engine that has the correct crankshaft at least. If you could buy that for say...100 bucks, then you could rebuild it for another $400.00 tops as long as it could still be bored out. Talk to a local machine shop that is experienced with K/M engines and find out what they charge for boring, decking, valve work etc so you know in advance what you are getting into. You should not go into this project unless you intend to keep and use the tractor for another ten years because you won't get your money out any other way.   [Reply]  [No Email]
