Tonight my stream 6060 froze up completely. The pump vibrated and made noise when energized, but the prop did not turn. When taking the unit apart to clean, I noticed the magnet assembly spins freely and independently when you hold onto the prop end, and vice versa. Also, no matter what I did I could not get the brakes to extend. The magent was not cracked and there was not debris present. Do I need a new magnet/drive assembly?

It sounds like the brakes have something in them, maybe a piece of debris such as packing material or sand. Follow the dissassembly procedure outlined in the manual and you should be able to fix it. The brakes should smoothly ratchet in and out. when you hold the prop in one hand and turn the magnet back and forth, when they are out and you twist a little further they should pop out all the way and come free. You could try soaking the drive unit in vinegar and warm water mixed 50/50 overnight and see if that fixes it, wont work if it is packing peanut pieces.
Oh, I see the prop spins free of the magnet. You are not using this on a wavemaker are you? That would destroy the brakes and is prohibited in the manual. I think you got a spare allready, can you remove the top half of the one with the broken magnet including brakes and put it on the good magnet, the details are in the manual.
When holding the prop the magnet spins freely 360 degrees with no resistance at all and the brakes don't extend, regardless of which way you attempt to spin the magnet... Took the brakes out and they are clean as well as the white piece they sit in. This is very confusing because I could have sworn that the magnet did not spin freely like that.

No, it shouldn't this means the brakes are broken on the back half. I know that you got a cracked magnet and a new drive unit was sent out, can you put the brakes from the other unit or better yet the entire top portion which will pull off when the brakes are removed from the old unit and put them on the new unit. Please though be sure you are not using a wavemaker, this damage almost exclusively occurs with wavemakers.
I did not get a spare, the magnet on the prop drive shaft was cracked completely in two when I bought it. So I asked champion to get me a new one. Although I bought it new from champion, I could swear that it was used because of the condition of the unit and the packaging. Oh well...
I sent you the replacement unit, if you have the old one part it out and use the brakes. I can send you one but I am concerned as to why this happened, this is a very rare problem and almost never happens unless a wavemaker is used or a bad power condition exists like frequent brown outs and power surges, even then this takes a month to occur usually. This would only be the third incident I know of in three years with this drive unit. Please call me tomorrow 512-833-7546, i have jury duty tomorrow so if I am not in leave a message. I can send you just the brakes free of charge. Please check out the pic
I'm not sure that the brakes are the problem, I just scrubbed them real good with vinegar and water and now they will engage and extend when I hold the prop and rotate the magnet.
The white piece that is attached to the magnet, is that supposed to spin freely on the magnet when disassembled?
After reassembly I tried to power it up again, but it did not work. If you take the unit out of the water and apply a little bit of pressure to the end of the prop shaft / screw head it will sputter then spin at normal speed and vibrate a bit. The minute you put it back into the water it stops.
I was not running it on an on/off wavemaker, I ran the powerhead continuously but turned it off for about 5 minutes each day for feeding the fish by unplugging it. For the past couple of days at turn on it would sputter and vibrate a little but would start. Today after trying to turn it back on it wouldn't start.

OK, I think I know what is going on- wrong size propellor. It sounds like somehow you got a pump with a 50Hz prop, it is larger because it spins slower on the proper 50hz frequency and so the motor is not capable of running it with the resistance of the water. Do you have calipers or some sort of Metric measutring instrument? The prop should be 36mm and should look a bit unfinished as it is the 50hz 40mm prop turned on a lathe. Without the brakes the white piece should spin freely. I investigated the possibility of the pump being used- it seems unlikely as the timing just doesn't seem possible. I recieved the pumps on April 12th, they got to Champion around the 19th. The time frame doesn't really allow for someone else to have had the pump. Unfortunately European environmental regulations require a box have a weaker glue and be made of an environmentally friendly construction. They do sometimes come apart and this happens with alot of European products I have dealt with. Anyway, i think we have found the problem, the heat and stress could have caused the crack the first time and the strain of driving the oversized prop is just too much. This would further explain why you thought two were too much for a 75, It would be a lot but not excessive.
I'll have the person I sold the other pump to contact you if he is having any problems.
To test to see if the prop is the problem, I unscrewed the propellor and tried to fire up the pump underwater. However, even with the prop removed the shaft does not start spinning. If you fidget with the driveshaft a little it will spin jerkily and vibrate alot.
I could email you pictures of the parts or ship them to you if you need to see them. I don't have calipers, but I have a metric rule I could use to measure the diameter of the prop.

Use your metric rule and send a picture, please PM me your address, I already discussed this with Axel this morning and the parts are free. But I would like the old ones back and we do need to confirm the prop isn't the problem. Also, please change every part, these parts have to wear together and if you don't change a top bushing or lower bearing when you change the drive unit it can cause problems, I would still save the parts as small pieces like brake shoes don't matter so much as long as they aren't broken.
Thank you very much for all of your help, I really appreciate it. I measured the prop and the diameter is 37mm. As you said it did appear to have a rough cut quality to it, so i guess it is the correct prop. I will send pictures to you tomorrow from work and the original parts if you'd like to see them.
