Another injector failure

[Coyote machine]

Gittyup,
The injection pump is probably the most complex item on the tractor because it has to meter precise amounts of fuel to all injectors through all load ranges. Not an easy item to fix, to build, or to have work properly these days with all kinds of fuel issues plaguing every type of engine in the diesel and marine fields. Something may have gotten past a filter and lodged in a screen and forced the pump to act the way it is currently.
Have you done any recent service work on the tractor- routine filter and fluid changes, or anything that might be leading to a: ...'ever since I did this the tractor is running weird?' type situation....
Unlikely it has anything to do with anything you or a service guy did, but the sooner you get the local dealer to look at it and verify the problem the sooner it will be fixed.
FWIW, when I ran my foreign car repair and sales business we used to replace, on occasion, diesel injector pumps on Mercedes diesels. There was basically no way to fix or adjust the pump, for the most part the best solution was to do a remanufactured part exchange, for which there was a ridiculous core charge to make sure the old pump went back to the factory for complete rebuild.

From what I remember from other post, there was a plastic gear in the injection pump that would break and bind up the internal workings of the pump. If that is what happened it would be nice to know if all of Kioti injection pumps have this plastic gear or if it's specific to a certain year, model.

Good luck with it and keep us posted.

The plastic gears are what failed in my pump because I disassembled mine to find out what was wrong. The gear teeth break off and then get jammed and cause the fuel rack to get hung up and then the governor can not do it's job. I'm not sure if this is a fuel problem or just a bad design. I'm sure that metal gears would last forever with just about any type of fuel. I have started using OptiLub XPD additive just in case it is a fuel lubrication problem.

I just got my Ck25 back Friday with a new injector pump, all cost except the hauling to and from the dealer were paid for by Kioti. What yours is doing is the same thing mine did. It runs great know.

And what would you like us to respond with?
I have seen my share of a couple of pumps and Kioti has treated every failure case by case.

Rick, has it just been the CK 25's that have been affected or have all of them had a pump fail?
Thanks

I spoke with the local dealer yesterday. They won't fix it in the field and want to charge for both pick up and drop off. Said they couldn't pick it up until Friday. Now I could transport it myself, if I could get in on the trailer (afraid to start it, if it even will). Local didn't give me a warm fuzzy they'd go to bat for me with Kioti either. Based on what they are quoting for pickup/drop off and "labor", I think the local dealer would end up costing me as much and maybe more than the distant one. So, I called Wallace yesterday and he is coming today to fix it at my house! Great response and service once again from Rick. I know it's going to cost me a few bucks. Don't know how much just yet. But, I feel more comfortable with this approach.

My real concern is will this pump be any better? Does anyone know if there has been a design change?

While Rick is there changing out your pump,and you have his ear, check on those questions(how common is this, is it confined to the 25's, was your failure the same{plastic gears}as others, etc.,etc Then you can let us know "the rest of the story"

We have seen it in the CK25 and 30.
I think we did one on and old style DK40 also.
From what I understand it was a hardness spec on the internal gears.
Yes it was corrected.
This is something that is a hit or miss what I mean is there has only be a handful of my customer that experienced this failure I have 3 times as many in the field that have not had this issue.

Well,alright rick,you did come and help again!
So,kiotis replacing on case by case basis,that don't sound good,what does that mean,if tractors have a newer pump they are not but if they have a pump with certain model they are or does it mean if somebody shows them a copy of this they will,or what??

When did they address this problem on assembly line? [mine was bought back last august].seems like the two here are at least three years old.

What [plus or minus a hundred dollars or so],would this cost,if you got tractor to dealer and picked up yourself.??
