Oil & Fuel Pour in fuel injector Cleaner

[nspec]

I apologize if this thread has been hijacked with a discussion about injection terminology. Getting back to the original discussion about fuel system cleaning...

I have to second Leonz advice about the Racor. Clean, water free fuel is of the utmost importance. There is always water in some amount, however small that may be, in diesel fuel. It can come from a variety of sources. My belief is that condensate is the chief culprit. Can form at the storage tank at the refinery, in the barge when it is being shipped, or even at your home storage tank or in the tractor itself. Water in diesel is where algae forms. In addition, cool water droplets sprayed through a hot injector tip at the engine can seriously damage injectors.

One last point on the injectors just to relate how terminology can cause confusions. There was some talk about how the Deutz's don't have injectors on their indirect injected engines.... My company runs (6) V-16 Deutz's - the model number is a TBD 620. They are indirectly fired and have a mechanically driven bosch lift pump. The pump supplies fuel to the rack which is timed mechanically and feeds mechanical injectors. I could take a picture of the injector for you if you would like - they are very conventional looking, albeit very large.

We have had some issues of late with diesel fuel dilluting the lube oil in the engine. There has been a lot of discussion about whether the injectors are leaking or whether the injection pump is allowing it's lubricating oil to seep into the fuel system. Either way, quality of fuel comes into play and with the new blends, a good Racor is very cheap insurance.

So I looked up some Racor filter systems. Web search lead me to the Mid Atlantic Engine Supply site. Was looking at their spin on series for off road use. It had a clear bowl at the bottom. The filters were available in 2, 10, and 30 micron.

The fuel filter on my JD 4520 is a 5 micron filter. Is there some other benifit to the Racor system that the "stock" JD filter doesn't provide? Don't know, just asking

The Racor 1100 model and others can be ordered with a fuel heater that is controlled by an automatic thermostat and heat the fuel prior to its entering the injection pump.

The stationary centrifuge spins the fuel and water and crap against the bowl walls using the pressure gradient created by the injection pumps suction and removes the water quickly as the water has a lower specific gravity and settles out quickly.

The 2 micron filter element will protect your fuel system and engine to a much greater degree and the engine will burn cleaner as well.


The use a of Racor fitration systrem at the dispensing tank will also accomplish this for you and remove the contaminants prior to dispensing the fuel for you so its essentially a protection vaue judgement where the filter unit mounted on the machine will protect it at all times and a Racor system mounted at the dispensing point will clear the fuel at the time of refueling,

You would be truly amazed by the amount of crap and water is removed by a Racor filtration system including weld spatter, algae solids, simple dirt and dust etc.

The Racors are water seperating fuel filters. The water settles out in the bowl at the bottom and can be drained off. This is accomplished by directing the fuel through a spiral type pathway similar to what a centrifuge would accomplish. The water and some solids are 'spun off' and travel to the outside of the filter housing then settling to the bottom. More than likely, the JD filter is simply a filter element. The racors have this cartridge filter above the bowl as well. Difference is that while the cartridge filter may trap water, once it does, it's all done. AND, you have no visual indication that it has. The Racors offer the advantage of both being able to see the water, and allowing you to drain it off, keeping water out of the filter element. This way the cartridge can keep on filtering sediment.

We usually run two filters. A primary filter of 10 or 15 microns and a secondary of 2 microns.

Yes, I have used a Racor Turbine filter for years, it did not have a heater, but to see the stuff that filter captured. The water would form at the bottom and it had a valve to drain it out, without losing prime. Unfortunately there is not enough room on my Kubota for this racor unit..I have always bought the injector cleaner that was made for the system,gas or diesel. But I was curious about the composition of it. I also know dirty injectors will plug up or pee...which really makes a knock on start-up..Thx. Jy

Can you run an 1100 on the ROPS and still be out of the way?

thanks to all for the replies and explanations :thumbsup:.

My Kubota B21 has a clear fuel filter but no drain. It is clearly just a fuel filter. My JD 4520 has a water drain under the fuel filter. On some JDs it is clear, on mine it is not. The canister for the filter is labeled "Final Filter Water Separator" and at the bottom it says "Drain Water Regularly". The tech manual refers to this as the "water separator" also. No explanation in the manual as to how it works other than pointing out that you should drain water off via the drain valve periodically.

In a good-better-best world, my B21 is good, my 4520 is better, and a Racor filter would be best ??

A retrofit on the JD 4520 tractor would be difficult. But if I ever did a fuel storage tank and dispenser, it's clear that a Racor filter system would be a must!

If you have room on the nose of that thing and it does not have a loader you can mount the racor 1100 or other model there using the four mounting holes on the filter canister or your rops as long as you can run fuel line the number 4 hydraulic hose is perfect for this application.

Okay, What is the major difference in the fuel injector cleaners, that are poured into the fuel? I have bought two differnent types before, Gasoline powered and diesel fuel type. I have never paid anyone to take them out and clean them on any engines. I did pay once to have the nozzels on my truck replaced and re-calibrated, with out noticable difference in performance or smoking?.{6.2 Chevy}.Jy

You should and use a diesel fuel specific additive. Do not use anything that has acetone as an ingredient.
There have been several studies done on fuel additives, and some of the results are suprising.

hope this link works..
Personally, I run KNOWN good clean fuel, and every great once awhile, I will add a small amount of Caterpillar fuel conditioner.

Hi can anyone tell me how to clean and what to clean fuel injectors for a case 885 diesel tractor (?1989 or so) thanks Tina
