Kioti CK25 Quit Running

[Kitaquickflash]

I have a 2008 Kioti CK25 with under 200 hours. I was using it for a couple of hours yesterday and then again for 45 minutes today with no problem. All of a sudden, it lost power and fizzled to a stop. It was like a golf cart that lost battery power and dwindled to nothing. I tried to restart it and it started briefly, but had no power. After that, I could not fire it up, but it would continue to crank. I had half a tank of diesel fuel and the oil is full. It was acting like a fuel issue, so I removed the fuel filter housing / container (a screw on container that looks like a small mason jar). I emptied it and checked the filter. There was some minor specs of debris, but nothing major. I replaced the fuel filter housing / container and tried to start the tractor again, but all it would do is crank (would not fire). I bought this tractor new and it always fires right up like a champ. I noticed that the fuel housing / container is not refilling. That made me wonder if I have a fuel pump issue. Then I checked some "threads" on this site and I am seeing references to an injection pump. I can't get it on the trailer, so I can't take it to the dealer, but I was figuring that if I could narrow down the problem, I might be able to remove the part and take it in to the Dealer. Any ideas? Thanks

Check to be sure tank is venting IE check for good fuel flow from tank to inj pump. Inj pump will be located on the side of engine and have steel injector lines leading to the top of engine. Do you hear fuel control solenoid "click" when activating ign switch?

If fuel filter is not filling, you have a problem of obstruction between the filter and the tank. I am not familiar with your tractor, does it gravity feed to the filter(tank higher than filter) or is there a fuel pump in the fuel line somewhere (in the tank or elsewhere) on the tractor. If it is lower then I think your fuel pump is faulty.

Thank you TX Jim and Gary. The fuel tank is above the fuel pump / injector pump. I was able to use a "come-along" to ratchet the tractor on to my trailer once I got the front end loader disconnected (I was worried that I would have more trouble with both of those tasks since the tractor is not running), so I am going to run it over to the Dealer and let them figure it out. I am handy, but not mechanical. I appreciate your responses. I will let you know what they come up with.

That is probably best. Injector/fuel issues often have to be solved on the machine since taking any one part off introduces more air into the system which is a problem. Injectors need many thousands of PSI at low volume to open and any amount of air can create enough " bounce" or "cushion" that the injector is not forced open

I took my CK25 to the Kioti Dealer today and he confirmed that there is a pin stuck in the closed position in the rack in the injection pump and it is not allowing fuel to pass through. There was no warning and no odd behavior. As a matter of fact, the tractor was sitting and idling when the problem occurred??? The Kioti Dealer has agreed to send the rack to a local Diesel shop to see if they can rebuild it. I am hoping that they can as a New Injection Pump from Kioti is close to $1,000 (I don't think that that includes labor). Hopefully I will get some good news.

Out of curiosity, do you treat your diesel with an additive? Likely it may not have made a difference, but I would be curious what the mechanic that rebuilds it says. Injection pumps are lubricated by the fuel.

 

[Kitaquickflash]

No, I have not utilized an additive. I have just used straight low sulfur highway diesel like what I put in my F350 Turbo Diesel. I will definately ask the mechanic what he thinks about an additive. I have been told that the off road Diesel does a better job of lubricating the parts that it touches.

Off road diesel at one time had a higher sulfur content than on road fuel and lubricated better.
For the past several years both on road and off road are low sulfur. I believe the only difference between the 2 is the red dye

There is another thread raging over this very subject. Very curious what the injection pump dude says. I don't know, so I play it safe and use an additive.

 

[Kitaquickflash]

That's funny Vince. I would have guessed based on what people say, that the difference was immense. I guess it started out with some reality and has turned in to one of those urban myths....ha, ha.

 

[Kitaquickflash]

Which additive do you use TomSeller?

Which additive do you use TomSeller?

I use Power Service grey bottle because it is so available. I rates out fairly good, but not the best.

 

[Kitaquickflash]

I appreciate it. I will definately try using an additive once I get the tractor back. Better safe than sorry!!

There are reliable rebuild shops for the Kioti tractor IP's. See what your dealer comes up with first, but you will be spending some serious $ whether you rebuild your original pump or buy a new one. $1K won't cover labor from a dealer for a new pump.

You are exactly right, I don't know why they diagnosed it as the IP when the filter bowl isn't refilling; tractor won't run without fuel???

Take your line off from your tank to your fuel filter and blow back through it, it will discharge the blockage in the tank nipple. Mine does it constantly from crap in the fuel. I have pulled fuel tank washed it cleaned it blah blah it still does it, the nipple is molded into the bottom so it will pull every peice of crud out of the tank it should have had a half inch riser in it in the tank so it wouldnt pull the crud out of the bottom of the tank. I have to blow mine out about once a week.

 

[Kitaquickflash]

I apologize, I should have clarified something. I spoke to the Dealer on the phone prior to taking it in and he walked me through a few diagnostic steps. It turns out that I had not been cranking it long enough (I did not want to run down the battery), so that is why I thought that the bowl that houses the fuel filter was not filling with fuel. When I let it crank, it did fill up. Additionally, we tried bleeding the air out of the system to make sure that that was not the issue, but it was not. I picked the tractor up this past weekend and they had been able to rebuild the Injection Pump. I got away for $475 plus tax, so that certainly beat the injection pump replacement that others have experienced.

What exactly was done to your IP for the $475? I'd want a detailed list of parts replaced, before and after tests on the pump, and a written warranty on how long, time and hours that the warranty covers.
Glad you were able to get it fixed. Going forward I'd want to make sure your fuel supply is clean, fresh, and check/drain your fuel bowl and change fuel filters on a regular basis.

 

[Kitaquickflash]

Since the Dealer sublet the repair to a Diesel Repair Shop, I am not sure if I can get the breakdown of exactly what they did, but I do have their name, so I will give them a call. Good idea. Additionally, I am going to start utilizing a Diesel fuel additive. Thanks
