View Full Version : 6055 clicking again??

Wondering if anyone else has had this issue. I have a 6055 that is around 20 months old. When I first got it (along with a 2nd) I could not pulse either of them from 0% power without it "clicking" every time it spun up. Had to keep them at 30% min to avoid the maddening noise (they are on an aquasurf) Roger hooked me up with the graphite discs and redesigned propellers which made them dead silent (YAY). Eventually got a good 1"+ wave going in my tank running 2 of the 6055's against a 6105 (6' tank)

Now, I maintain the pumps every few months and the last time I put them back in, I noticed one of the 6055's clicking again - but not all the time :confused: I disassembled, reassembled, checked the little graphite washer, even tried one of the old props (that clicked every time) so I'm at a bit of a loss - The 2 6055's run off of the same port on the aquasurf so I had to change the power from 0% to 30% to keep from going mad.

I'm not sure if I somehow have exceeded the duty cycle of the prop (It pulses 0-100 every 1.1 seconds for 12 hours and then 0-70% for the next 12) If so...I imagine I can just get new guts and fix the issues or should I not be pulsing the 6055's?

Also, is the aquasurf driving the Tunzes properly, or is there a functional difference between it and the actual Tunze controller?

Sorry bout the lengthy post - I'm just scratching my head on this one.

Check the prop, it should be stiff on the shaft, if it turns easily, it has just worn out.

It does not turn freely but it does turn. :( Not sure what sort of tolerance I should be looking for but it it likely that it's simply worn out?

If you hold the magnet of the drive unit in one hand and turn the prop with the other it should have a fair amount of resistance, if it turns freely until it hits the stop, then it is worn.
