Opinion? what is the best Ultrasonic Cleaner for injectors

[whunter]

Both of mine died:
* Stopped working.
* The casing disintegrated from garage chemical exposure.

Here is what I am considering at the moment.

This is the one I have...

Ultrasonic Cleaner - 2.5 Liter

A little bit more pricey than the HF one you linked but it's larger and works nicely. I did all five of my injectors with it and it worked great. I put some gas in a small container and then floated that in water in the ultrasonic cleaner. Didn't want to put fuel in the ultrasonic cleaner in case my wife wants to clean her rings or something.

I used a small brush and some gas to brush them off a little bit then let the ultrasonic cleaner do the rest.

I had the Smallest Harbor Freight Ultrasonic Cleaner and it worked but after about 4 years the circuit that is in the lid Hinge area had issues. I have never tried to fix it.

I bought the next Larger Harbor Freight Ultasonic Cleaner and it also works but I have used it to clean other Parts and find I wish it was bigger. However, if you want a larger Cleaner the Price jumps way higher.

I have been useing Water and something like Purple Power as the Cleaning Solution.

Go for the gusto and make your own 600W ultrasonic cleaner (5-7 gallons).

10x 60W transducers @40Hz with 600W generator. Costs around $450 USD for the parts and shipping thru Ultrasonic Cleaners*|*Beijing Ultrasonic You will need a 1-2mm (max) ss tank. Hit the scrap yards. Making mine right now. News at 11 ...

In ultrasonic cleaning you need to consider the size of the parts you are trying to clean / the size of the detailed bits on the part you are trying to clean. If you are trying to clean inside small crevices for example you need to be using higher frequencies. It isn't just about the power rating.

Here's some reading

Ultrasonic cleaning - Wikipedia, the free encyclopedia

I hope it helps with your choice. I can't give specific model advice as it has been some time since I used them in my work and I've forgotten what I used to use - sorry

The above is true, but 40 Hz is the generally accepted transducer sound wave. Look at the players who make these contraptions, and 40Hz is their rating. You can get different transducers, EG, 28Hz, 40Hz, et cet., but you will need a generator which sweeps thru the frequencies. That type of generator costs a fortune. The real key is the power. The HF you are looking at is no more than a "nominal" 35Watt. Compare that against a real 600W and apply the 1 gallon of liquid for every 100Watts of mojo.

I will buy one this week.
Still not firm on which unit.

Let us know what you get - I'm almost going to be in the market for one in the future perhaps!

i've been using the HFT one for some years now, the basket melted after 1st use, but it works as intended without it. gets everything very clean. i wish the stainless steel bowl would extend all the way up to the top since that plastic area is starting to melt as well

I plan to get one tomorrow.

Is there anything in the body of the injector that requires cleaning?

Or, in different words..........if the nozzle is replaced, is that process sufficient to fully recondition the injector or does the body also require some type of ultrasonic cleaning?

I need to make a plan to get the Monarks installed.

I imagine it's not a bad idea to clean everything. Think about how hot the injectors get, and the couple thousand of gallons of fuel that are pushed through in their lifetime. I imagine that some kind of glazing would build up at least.

More than a couple of things cause the Injector Nozzle to wear out.

The little Pintel is being pushed back down by the Spring that is inside of the Injector and beats on the Metal seat when it stops.

Carbon particles from combustion and particles that make it through that 10 Nominal Micron Secondary Spin-on Filter get between the seating area and when the Pintel is pushed down smashes them into the seating area imbedding some of it into the Metal.

Not unlike fast moving pressurized Water erodes through solid Rock the Diesel Fuel erodes the Steel including the seating area.

Combustion errodes the exposed tip of the Injector Nozzle. If the errosion is bad enough it effects the Injector Spray pattern.

And added to the above stuff Heat and temp change stresses.

It is entirely amazing an Injector Nozzle survives as long as they do.

Where I used to work We reserved the Ultra Sonic cleaning Tank mainly for used Direct Injection Nozzles because picking out the Holes to clean them could enlarge them and at the same time was time consuming.

Used IDI Injector Nozzles could go the US Cleaning Tank but We normally used Carburator Dip on them to disolve the Carbon.

In fact both types of Injectors were taken apart and went into the Carburator Dip and were then hosed of with Solvent.
Any exterior Carbon was wire wheeld off with a very fine wire whee. (but not the tip where the Holes are).
So Nozzles going into the Ultra Sonic Tank were already pretty well cleaned. Unless there was some unusal problem the Injector Bodies did not go into that Tank.

Unless the passages inside of the upper Injector Body are rusted inside there is no abosolute need to put them in the Ultra Sonic Tank.

What you really need to get out of the passages on the Injector are Lapping Compound or if you use abrasive Paper to lap with. That can be done with Brake or Carburator Cleaner and compressed Air.

With compressed Air it is best to have a Filter and at the very least something to separate the Water out of the Air.

I can remember getting ready to assemble an Injector dipping the Parts in Diesel Fuel and blowing it out or off with Air only to shoot a lot of Moisture into it because someone had not drained the Water Separators.
It just causes you some more cleaning time but it is better to think about it before it happens.

But, I had the littley HF Jewlery type US Cleaning Tank for at least 4 years and I used it more for cleaning other parts then Injectors. Limited of course by the size.
I have had the Larger HF one for at least 2 years and the Larger size helps alot.
One of the last things I used it for is I threw My original Ignition Lock Tumbler inside and gave it a good cleaning.

I think if a Person buys one of those Tanks they will find themselves putting all kinds of parts into it.

For those who plan to re-use the good Stock Bosch Nozzles. Even if you can come up with the right Sized Music Wire to clean out the tiny drilled passages in the Pintle tip that will not get all the Carbon out. But, an Ultra Sonic Cleaning Tank has I believe will.

I noticed most of the guys posting on this topic seem to be diesel. Can you put gas injectors into the ultrasonic cleaner,and what do you use for solvent?
