Kioti Injection Pump Failure Data

[edlite]

How do you reset engine stop.Iam not getting any fuel to the injectors. I have a CK20 ,purchased in 2006 .Engine stop botton does not move.It is all the way in and lever does not move on manual connection attached to injection pump. Fuel filter pluged and engine quit,replaced filter and there is fuel being pumped to IP but no fuel to injectors.Engine shut off was pulled by error and then pushed back in.It does not come back out. I am at a lost as what to do,any help would be welcome. Thank You

CK25
2007
Failure at 320 hours
Jammed rack, missing teeth
Local rebuild / rotated gears 180
Zero help from Kioti or my dealer.

Tractor has been babies since new and stored in a climate controlled garage! I am in the market for a larger cab tractor and Kioti is the only brand I have ruled out!

Thanks for the data. I updated the spreadsheet. FYI, the folks at Conestoga Diesel tell me that this failure is quite common in small agricultural Diesel engines of many brands. I suspect the difference is lack of support from Kioti US and some dealers. As you (and many others) have found, the fix can be fast and relatively inexpensive if you are willing (and able) to dissect the IP.

Ruled out because they wont warrantee a 8 year old part. Don't think any manufacture will help you on that one. I have a couple of leaky seals on my 1993 Ford 1920. Do you think New Holland will fix them for free? Parts on all tractors will fail and need to be replaced. Some will be under warrantee and some will not.

But that year tractor has a well known issue with that problem at all hours. Kioti should (but doesn't) do something other than replace the ones that happen to fail under warranty.

I have a 2006 CK30HST and had two injector pump failers,The first was around three hundred hours and Kioti repaired it under warrant, The second was with 915 hours and I didn,t ask for any help since I have owned this tractor new since 2006. The first time the rack was sized and this time I really didn,t want to know. I still think they are a good machine and would probably purchase another one, I have a friend who has a two year old JD and nothing but problems, I am not protecting Kioti but there are problems with all brands,

I was at my Kioti dealer yesterday and he had a CK25 in replacing the IP. It was the second time he was doing it on this tractor. I commented on this being a big concern of mine on my CK30 and that I thought there was way to many for Kioti to just ignore the problem. He quickly told me that in all the years he had been selling the CK line of Kioti's that he had only done about 7 or 8 IP replacements. I asked how many tractors he had sold and he said between 80 and 100. That comes out to a possible 10% failure rate. He didn't think that was a lot. I had to disagree.

When I see more complaints about 2005-2008 Kioti tractors fuel pump failures than all the other brands combined, it sure seems a lot to me !!!

10%! that's terrible! 80-100 tractors is a significant sampling.

I wonder if that is higher than the infamous cracked loaders or leaky HST oil coolers. I have had none of these probs
on my 10yo CK30, and the other one I bought at the time, which is pretty beaten-up, has not suffered these issues
either.

I'd disagree too. If there was a 10% chance of falling out of the sky every time you flew on a plane, no one would do it.

2006 CK25
New style pump
failed at ~320 hours - stuck open full throttle
Kioti replaced under warranty

I have same problem.. No warrenty... Still checking how to repair full throttle ck35.. Any help .. Pump was operating before i removed and cleaned , installed back. Solinoid was the problem. Any help.. Could i have set off timming????

 

[ritcheyvs]

Timing problem unlikely unless the IP camshaft (in the block) is broken. Very rare but it has happened (the back end of the camshaft drives the hydraulic pump). Not clear what's going on here. Did you have runaway before you removed the IP or after? Maybe you can describe what happened when. "Pump was operating before i removed and cleaned" doesn't make sense; why remove a pump that's working? How was the solenoid the problem?

This may not be your problem but typical scenario is either no start or sudden high engine RPM. The typical cause is broken teeth on the gear portion of a control sleeve inside the IP. Even after successful repair the tractor will be hard to start until all air is purged from the IP and injector hard lines. A new IP from Kioti costs near $1K but you (or a Diesel shop) can replace all the control sleeves for about $100. Presumably, new/current control sleeves are tougher than the 2006-2008 version. The actual repair is an easy DIY job but, having said that, it's just as easy to reassemble the IP wrong.

I thought it wad pump failer thats why i disassemble it and verified it to have good teeth . just opened ip again and realised it was the pin that holds evrything was probably set wrong way. Thats why my pump accelerate.. Hoping this is my problem. Dont know which way it goes. Pin Has a cut i. Middle..

 

[Joe vega]

Hope someone can tell me direction on installment.

 

[ritcheyvs]

Joe, I think we may have confusing communications. I'm not certain what the pin is or where it is in your photos. Like I said this is an easy job but also easy to do wrong. It is critical to have all plungers and control sleeves correctly aligned to shut off fuel injection with the rack full aft. The dots on the gears must align with the lines on the rack (when centered) and all plungers must have the slot aligned correctly (not 180 degrees off).

Instead of me asking a lot of questions I'd recommend you review this site if you haven't already. The author took a lot of time (plus many photos) to explain theory and repair for these agricultural IPs.

 

[Joe vega]

Was able to repair pump .. Starts right up..first click.. Tthe thing now is i added 100 hrs to meter and don't know how. Every time i would try and start it it would accumulate 5 to 7 hrs.. Now that its repaired its back to normal.. Funny ....lol it has 1102 hrs now.. Is there a way we can deduct hrs on tractor....???? Thanks 4 the help...
