06 Kioti CK 25
****-o,
I have an 06 CK 25 that had ignition switch issues and then started stalling but would restart but only idle. It sat overnight and I ran fine yesterday. I went ahead and replaced the electrical part of the ignition switch. It ran fine and then free revved at 2500 and would not shut off. It finally went back to idle and I turned it off with the key. Now it will not restart at all, it does turn over. Any ideas?

What you described (high rev, won't shut off, then wouldn't restart) is the classic symptom of injection pump rail failure. Gear broken in the fuel rail.

I've seen posts about it on here. I was an auto mechanic at one time but know nothing of diesel. Is this something I might be able to repair myself? Any leads on here of attempting that? my searches have come up empty.

Welcome to TractorByNet!

I moved your thread to the Kioti Owning & Operating forum. :)

I agree with SSdoxie. I believe your year of tractor was one of a few that had the injection pump gear problems. I was also a mechanic with no diesel experience but I'm sure you can handle this job. Unfortunately, a new injection pump is around $1000. A member was trying to keep track of the years of pump failures and it seems like 2006-2008. Another member posted this company, diesel fuel injection turbo, Conestoga Diesel Injection injector fuel pump turbocharger willow street pa Willow Street, PA Home, that can repair the pump. If you search for other injection pump posts, you'll see pictures from other members who have disassembled their pump and the broken teeth on the gears. This post, the member found new gears and was repairing it himself. Ck 25 Injection pump rail timimg???.

Would be nice if we could get a Admin to sticky this to the top of this thread section, making it a lot easier in the future to find.

Yep. Sounds exactly like my '06 CK25. Injection pump. How many hours? They usually failed around 300 or so. Mine failed at 330 hrs as I recall. Luckily still under warranty. I'd the rebuild route first, since you have mechanical skills and contacts too, I'm guessing.

Here is the link to the IP failure data I've been collecting: http://kittrellcommunitywatch.dyndns.org/Kioti_IP_Data. There are links embedded in that spread sheet that may be helpful.

Before you do too much, verify that the IP is your actual problem. Remove the cover plate with the oil fill port on the right front side of the the engine. This should expose the pin that controls the IP rack. With the stop solenoid (another possible cause of your problem) removed the rack (pin) should move smoothly by finger pressure. If it is jammed or binds, you have a problem with the expensive injection pump.

If you remove the IP, don't lose the gaskets or shims, they set the injection timing. You WILL want a service manual before going into the engine. You can buy one from any Kioti dealer. The service manual isn't great but it's better than nothing. There are good, free online parts manuals like this one.

A new IP will cost about $1000 from Kioti. The same part should be cheaper from a Bobcat dealer. You may be able to repair your current IP (by replacing damaged gears) if you have a local Diesel shop that repairs IPs.

Several list members have replaced their IPs successfully.
