Part number for injection pump from Bobcat is 7010240 if you want to do a price comparison. Might want to start with Kioti dealer first, they might be able to get a partial warranty discount because of the "known" problem.

Okay so after speaking by phone to Tony, another member I decided to tear it apart. It didn't take very long at all and with the intake removed it lifts straight out. I guess I was lucky because the rack was jammed in the center position. Once I laid it on the bench it magically freed up. I took it apart (IP) and the #2 pump gear had a single tooth sheared off and embedded in the rack. Given my current financial situation (divorced) I really cant afford to replace the pump. I am trying to find a place to buy gears, I may just rotate them and slam it back together. I did contact Kioti customer service and left two messages and so far there has been no response. 06 CK 25, 275 hours. Purchased new in 07 with 2 hours on it. Thank you to everyone that has been so helpful. I will post on the outcome one way or the other.
I could use gears too. I have one with a tooth busted off clean in the middle, so I can't really rotate it. Also, the other 2 gears show wear. They look like real brittle metal components to me.
Let us know if you find a supplier.
Mine only had one tooth sheared off. You just turn it 180 from the rack. The pictures another member posted for time were indispensable. Make sure you thoroughly check the rack because I had to clear the broken tooth from the rack. It was fairly easy to do. I don't trust the repair however and will limit use of the tractor until I can find a set of gears or save for a new pump.

The above site claims to be a manufacturer in India that manufactures these pumps. I sent them an e-mail to see about purchasing gears and a rack for the IP. I will let you know if I get anything back.
As for the repair? The tractor is successfully running once again and out of the woods. I made my own intake gasket as the local dealer didn't have it in stock. For those of you that have done this it is really easy especially with a gasket punch. The photos for injection timing were invaluable. So with gasket material and a tube of the grey RTV a total cost of $10 dollars and a couple hours working on it, maybe a little more but not much. Some things I learned are to just take the hood off. Remove the injector lines completely and remove the intake manifold. Take the throttle stop out and the other piece on the other side of the housing. The pump will lift straight out if the rack is not jammed to one side. In my opinion the gears are a porous very hard material that I have seen before in Asian products. It does appear to have a high potential for shearing off. Reading other posts I wonder if the idea of the throttle stop contributing to the issue. I will say that I had been having issues with the ignition switch for awhile and even after disassembly and cleaning it still gave trouble. I would definitely say that for those of us that have dealt with that it certainly doesn't help the throttle stop question regarding the gears.
The tractor does seem to run much better, idles smoother and seems to respond more quickly at the throttle. I am happy to have it running with little cost but I am afraid of the potential of another failure and a runaway diesel you can't shut off. I will continue search for repair parts. I want to thank everyone that has been so helpful. If anyone needs or wants any help regarding attempting this repair feel free to e-mail me and I will give you my cell number.

If you do have a runaway, block off the air intake as fast as you can. It will stop. This one is tough because the air cleaner box intake is just above the battery. One of those posts in my prior post has a member who bought gears from I assume an injector company close to him. Maybe he can help for a supplier.

If really concerned about runaway RPM, put an inline electric shut-off valve in fuel line close to where it goes into the injection pump. A quick search in Amazon.com, I found this one.

A ball valve will do the trick also. A little more difficult to get to but it will work. CJ
So I faxed Kioti and finally got a call back. The short version is I was told they wouldn't help with anything. Not even repair parts. I explained that I wasn't looking for anything free! I was told I would need to buy a pump! I was also told I wouldn't be able to get the pump apart and back together. Ha! Anyway I am just going to run it and I will put a fuel shut off in between the filter and pump.
Sorry to hear you got one of the IP pumps with brittle gears that Kioti refuses to take any responsibility for, i.e., unless it occurs during your warranty period. There should be recall laws. It can be very dangerous when the gears on these get stuck. The problem is constantly chatted up on this site. Best of luck with your gear rotation repair!
