Best ultrasonic cleaner....

[tkent02]

The one I use is a 30 liter unit, I can just fit a 16 valve head or cylinders in it.

Which unit are you using?

[tkent02]

If he does accept the make offer, let us know what it is since he has more then 10 available.

So far he has turned down $250 and $295.

works very well, I use a cleaning agent called Brulin 512 http://brulin.com/productdetails.aspx?pid=135&cid=49

It got here, or rather it's been here a week and I just got here. This one:

Cheaply made, the instructions and labels are worse than those with a 1965 Japanese bike. Says not to fill it above the line, guess what? There's no line. I'm guessing an inch from the top is OK, just so it doesn't overflow? Maybe I should measure 22 liters into it and mark the side of the tank? The power cord is some goofy foreign thing that I've never seen before, and I've seen a lot of them. At least it comes with an adapter, which works. The heat is slowly getting hotter, up 6 degrees C in 15 minutes. Not really that impressive.

Put a 650 head in the basket, it fits. A 750 or 1000 head will fit with no basket, will have to rig up something to hold it off the bottom. It's been in there fifteen minutes, the water is definitely getting murky.......

I need a way to carry 6 gallons of hot water out to the garage. OK in the kitchen this time because my wife wasn't home. If I dropped something heavy on her new countertop it wouldn't go well for me. Got away with living dangerously this time.



Fits the head, a lot of dirt came off in a hurry.



Didn't really get it all that clean, even after a lot of cycles. There is still a stain from the old baked on crud around the spark plugs, there is still some carbon in the combustion chambers. I think the mass of the head is just too much for it. It did better on a valve cover and some smaller parts like a master cylinder and some pistons.

Maybe a different detergent would work better, used the Simple Green professional stuff. Maybe need to soak it longer, maybe need it to be hotter, or more concentrated, not sure.

[Fjbj40]

Is it heated? The one I have will get to 80 cel easy. Once again I use a mil-spec degreaser/decarberizer. That may be the difference? This stuff cleaned every bit of carbon out of the combustion chambers! It also started lifting the paint!

bummer that you are not getting the same results?

[tkent02]

It's heated, I only went to 55 degrees C. Maybe hotter is better? It says it goes up to 80. I'll try it. Also I didn't use much of that detergent, maybe I'll try a lot more. You using 9-1 on that Brulin stuff like they recommend? I didn't go anywhere near that much.

Lifting the paint? Cool! If it could remove the paint that would be great, I want to powder coat all of the engine parts.

WOW that is a nice large unit. Mine is 300 W and almost like the first one in the top post but the name is different.
I must confess, I found some professional chem dip and haven't used mine since but wonder if I should follow up with the ultrasonic too.
I still am unsure of what to use in the tank.
subscribe to this one to see what you are all using for the cleaning agent??

[tkent02]

Using this stuff:



Got it hotter, added more detergent, did a few more cycles, the head is getting clean now. Not removing paint but the carbon is gone, it looks really nice....
One more cycle and........

Snap!!

Made a sound like a fuse blowing and silence. The timer is still counting down, the heater is still heating, but no bizzzzzzz.

Have to check into it tomorrow after it cools off.

[tkent02]

This is where the smoke came out....



For you electronics guys, where can I get one of these?

?????? Maybe 1 out of this set

[tkent02]

These look the same:

[posplayr]

I would google the part number to see if you find amatch the find an alternate from there; if you have an exact match then ok


the one you picked from amazon looks right.

[tkent02]

OK, whatever you do don't buy this one. Very poorly made circuit boards, can't do any soldering without tearing up the area around your repair. Pretty much garbage now.

[JTGS850GL]

Sorry to hear of your recent loss. It's one reason I either buy known quality or build my own. The two things that damages cleaners most is running it with little or no fluid or running it for too long a cycle or to often without time to cool down.

Let me know if you want to part with it. I might be able to use the tank and heater assembly to augment mine. You could replace the transducer driver board as well.

If you still want to consider repair then the part is a 400V .33uf Metallized Polypropylene Film Capacitor. Should be able to pick one up from any number of electronics supply houses. Might want to try digikey.com. Here's a search that came up with it: http://www.digikey.com/product-searc...=0&pageSize=25

You might want to consider going up higher on the voltage rating if that one blew. You can always go up on the voltage, just not down. Be warned that that component may not be the only thing damaged. It may have let the smoke out but other things were probably compromised in the process.
