Engine Rebuilding

Recommended Posts


Hi All, I have a couple of questions for you:

I went to look at a tractor tonight which has a Kohler K241 10HP motor in it. Unfortunately it is locked up. The tractor is in great shape, minus the motor. Owner says he doesn't know anything about it. I could get the whole thing really cheap. I guess what I'm asking is could the motor potentially be rebuilt, or a waste of time? There's no holes in the block, and nothing other alarming that I saw, except when you go to turn it over by hand it won't turn. To me, it's worth trying to fix because it's a tractor I have been looking for.

Another question I have is where does one have an "engine rebuilt" at? I hear people getting their motors rebuilt, for pulling and regular use, but I can't seem to find anyone to do it. I know it's not cheap, but I have a couple motors I would like rebuilt, including the above mentioned. I know it can be done somehow, I'm just having a hard time figuring out how to have it done and where to have it done at?

Thanks for any help!

Depending on why the motor is locked will determine if the motor can be rebuilt. I have successfully rebuilt a k241, and it is a great engine. It's definitely worth trying to fix because there really isn't that much too them. All you you have to do is pull the head and the pan it should be obvious at to why it's locked up. If your a bit handy, as most guys on this site are, you could probably do,it yourself. The parts are readily available either from Kohler or aftermarket.

As to where to get it rebuilt, that depends on where you live. By me, none of the lawn mower shops do that anymore. They send everything out, to where, I don't know. My only other option was to have a local machine shop rebuild it for me, but they weren't in my price range. So I got the engine specs from the Kohler repair manual, brought the block to the machine shop and had them measure the crank and bore. They bored it out .10 over, said crank was in spec. I ordered the parts I needed, grabbed the manual and got to it.

There is also a guy who does pulling engines, Brian Miller, he will rebuild your engine and / or sell parts. Google him, his website is a trove of info on these small engines. I learned a lot from that site as well.

I rebuilt a k241 and k321 a couple of years ago and they both have about little more that 100 hours on each of them and they run great. These kohlers are great engines so good luck!

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
