Injector Pump failure

[Singlemalt]

I think I'm going to join the chucklers.:laughing:

It's more than my grey matter can handle. In 35 years of owning Kubota tractors I never had any fuel system issues and expect the same from my Kioti.:thumbsup:

30 years from now they won't let me have a tractor, chainsaw or drivers license.

You might not want to mention this if you ever do have a fuel system problem. Maybe it helps or maybe not, but it would allow Kioti to get out of paying for a warranty issue.
Here's a link to the Korean standards for diesel. I'd assume the injector pumps would've probably been designed for this standard and then they did some testing and found they are OK with our fuel.
Fuels: Korea
Their lubricity standard is 400 vs. our fuels 520 micron standard, so for a couple quarters a tank I'm going to add the stanadyne lubricity additive. May not make any difference but it might help too, 30 years from now if I haven't had to mess around with the injector pump I'll call it a success!

Besides, it keeps all the additive manufacturers profitable.......

I guess it does that too...
On the plus side I found our local diesel injection pump rebuilders shop searching for the stanadyne snake oil. The owner has been running it for 50! years so its a bit of a mix of old tech and new. Who knows, it might be worth buying some stuff there in case my injector pump does go out of warranty. My dealer is pretty good but I doubt he knows as much about injector pumps as these guys do.

KIOTI does not have a stand on Fuel Additives. I can tell you from 25 years in the fuel shop business that an additive that raises cetane level, disperses water, adds lubricity, and prevents gelling can be nothing but GOOD for your diesel. Every tank...possible. Every other tank.... just as good depending on usage. ULSD, as its predecessor LSD, utilizes a hydrogen process to lower sulfur.Therefore, drying it out causing hard part wear. STANADYNE has some proven product for this and was utilized in my shop for years. One more thing for the record..... There was never any plastic gears in the injection pumps. After 25 years in the fuel pump business, I think it is rather funny some of the jokes put out!

Since ULSD only showed up at the pumps a couple years ago, data points of 10, 20, or 30 problem-free years without using additive may not mean that much. On the other hand, judging from the photos, I don't see how those broken IP gear teeth/rack teeth could be caused by lubrication issues.

Interestingly, we have a fleet of 100 on road trucks, all running ULSD continuously in ages running from 2010 models back to 2001 models in Cats, DDEC's, and Cummins and none have ever developed any fuel sysgtem problems related to ULSD fuel, in millions of miles and thousands of hours..

...and neither have my farm tractors or my diesel pickup though I do use Cat additive in my pickup because it sits for months on end and I don't want to grow algae in the fuel tank.

Our new IH failed with 50 hours on it. High pressure pump had to be replaced. Fuel related? Who knows.

Are you saying high psi FUEL pump failed?:confused2:

We sell new trucks and trailers as well (Freightliner and Western Star) and I'm seein g a lot of failures in engines but not directly fuel related. Most are emissions related. To make the new engines emissions compliant they run excessively hot and it's the heat that causes problems. That and the very complex electronic controls.

mechanics are computer technicians today, not wrench spinners.

You can't even diagnose a problem without plugging the engine into a computer, offloading the error codes and then downloading that information to the engine manufacturer so they can ascertain the problem so you can act on it.

Our illustrious government and their mandates have made the simple 4 stroke diesel more complex than any gasoline engine and much less efficient than they ever were.

Keep in mind that components like fuel pumps are no longer made here because of 'World Class Manufacturing' so components are made who knows where, by the lowest bidder and then quality and reliability becomes questionable....

and....it's only going to get worse...

Neither have I. I'm chuckling too.:laughing:

Additives are all snake oil but we use them because it gives us solace and that's it.....:laughing:

what do you do that you have 100 trucks operating??? your profile list you as retired??

as a maintenance item, I do not see any reason to run additives. With that being said, I have, on more than one occasion, poured ATF and 2 stroke oil in a tank to temporarily "fix" a truck to get it home. The ATF got poured in due to the owner accidentally filling the tank with approx. 10 gallons of gasoline.... We dumped 10-15 quarts of atf in the tank and got it out on the highway and switched over to that tank and burned it all out. This happened out of state while travelling...
Another truck, 7.3L PSD, started experiencing what appeared to be an injector hanging while out of state pulling horses.. We replaced the fuel filter, no help. Pulled the filter back out, dumped some 2 stroke oil in the filter base and another bottle in the tank, FIXED IT!!..
Drove the truck back to Texas without futher issue. After approx. 2 tanks of fuel, it started again. Gave it a shot of 2 stroke oil in the tank, problem went away!!..
The truck now gets a small bottle of 2 stroke oil every 2-3 tanks of fuel... If he forgets, the truck reminds him!!..
All that to say this, its been my experience that most diesels in good condition do not need additives, but if you have a unique situation or trying to get worn parts to last a little longer, then some additives will help mask an issue.
