New injector pump in tractor

The last time I knew of diesel the only difference between "pump" and off road was the dye and tax. I buy off road for my tractor because I don't have to pay road tax on it. I have also used "pump deisel if off road wasn't available.

Glad they covered you.
I run Power Source... the white bottle. Run it year round for the X-tra lube.

You can get it at wally world.

ATF works well too.

+1 on the Power Service.
I also like to run B20, for the added lubricity.

off-road + one ounce of marvel mystery oil

In the old days, off-road diesel had some modest amount of sulfur - which acts as a lubricant, while pump or on-road diesel had low levels of sulfur hence low lubrication. (OK - actually in the really old days all diesel had sulfur, then there was a transition where on-road had low sulfur and off-road had sulfur. Now, most all diesel is low sulfur or ultra low sulfur - regardless of on or off road and the only difference is dye and tax as pointed out earlier.)

This is probably what the dealer is talking about running pump diesel vs off road diesel. Either way, all the standard tricks work for adding lubricity...atf, marvel mystery oil, actual diesel lubricity additive, biodiesel, etc ...what ever your religion dictates.

I also own a Kioti, a 30 hp version, and run exclusively off-road diesel that is labeled as 500 PPM sulfur. Sulfur isn't what provides the lube but the process to remove sulfur for the current ULSD on-road fuel also strips the lubricity from the fuel. Despite the gov't claims that the lube is replaced by some fancy additive at the refinery, it is not. The ULSD is too dry and will ruin your engine over time unless it was designed for the ULSD as modern pickup truck engines seem to be.

In my Kioti, with 850 hours, I always run an additive. I am using up the last of my grey bottle power service but then I will switch to ashless two stroke oil made for water cooled engines. This two stroke oil is what I use in my ford diesel truck with excellent results at a rate of 1 oz per gallon. I'll do the same with the tractor. Do not use ATF in your engine. It is not made to be burned and can gunk up the injectors and combustion chambers. Biodiesel, even as low as B2 (2%) provides all the lube you need but it is hard to find.

So how old is your Kioti? Was it out of warranty? Mines a 2005 model and has no fuel pump problems, yet. Your owner's manual doesn't require off-road diesel and even if it did, the rules for off road diesel allow pretty much any diesel so long as it is dyed red and non-taxed. "Off road" is not a formulation, it is a tax structure.

I don't think that the sulfur actually provided the lubricity needed. It is just that the process that removes the sulfur also affects the lubricity. However, the producer of the diesel should then use their own additive pack to correct. As mentioned above, often the only difference between on and off road is the dye and the tax. Kioti's story sounds like a far fetched cover for "we initially sold you a bad pump". You can add back in whatever makes you feel better. I usually run the white bottle Powerservice in my tractor, more for antigel than any lubricity issues as my off road diesel usage varies enough that I might be running off road in December that was bought in July. The truck gets a shot of Powerservice once in a blue moon or if I have issues that I think may be related to fuel.

Kiotis have been having issues with a stuck "rack" in the pump. Apparently there is some plastic gear that is loosing teeth and so the fuel rack won't move. Hey, they can blame the cow farts for all I care so long as they replace the pump.

I had to take my Kioti DK45 in for service in September because it quit running. Found out that the Injector pump went out. Kioti covered the cost of the pump (over $1000.00). I had to pay 1.5 hrs labor. They said it was because I was running pump diesel instead of off road. They also said it wouldn't hurt to use an additive for lubrication, the low sulfer diesel does not have enough.
One of the reasons I bought the Kioti was the warranty.

Unless their warranty only covers parts, they should also cover the labor....off road is cheaper and likely has no additives for gelling, and if its stock is rotated it likely has the same formulation of the pump USLD. Sooner or later as long as the off-road isnt sitting for years, it will be replaced with a ULSD formulated version...just its dyed a different color (for indentification purposes) and there is no levied tax on it so its cheaper....

Nothing wrong with adding additives, especially during the winter - when the USLD first came out they didnt have the right winter blend, and there were many reports of gelling (trucks, tractors, etc)....looks like its fixed but you never know

Lucky. I have a old oliver 55 with a worn head in the injection pump. Its an american bosch pump that hasn't been made for years. Last time I checked they wanted 900 dollars for a rebuilt pump with the old exchange. I can get a used pump for 350, but theres no guarantee. Even then I would rather have a diesel than a gasser. They run forever on a tank of fuel. My engine has been rebuilt, but I need a pump. Just right now too much.

My Kioti is 2yrs old. It only has alittle over 200 hrs on it. The dealership was going to see if the labor was covered, since it was only 1.5 hrs shop time I just let it go. I started with a dk35 and upgraded to the dk45. I haven't found this tractor lacking anything yet. I have a Farmi winch, backhoe, brushcutter, disc, forks, backblade. I had a case skidsteer but found the tractor much more versatile. I picked up the additive at wallymart, cheap insurance.

Kioti's are great machines, thats why Bobcat sells them under their name - which I think is great especially with the extended support/presence they have.... as a whole injector pumps are ridicoulsy expensive on any brand....Im glad you got it under warranty
