Older 6055 clicks on startup

[jscarlata]

roger
i have a pair of used 6055's in my 46, one of them constantly clicks when it starts. i'm using anew 7096 to control them in wave mode, so the clicking is constant. I recently bought 2 new drive units for each pump and it did not fix the clicking...what else can it be?

thanks
John

The disk, 6055.700. This is easy to change with the right tool. You need something like our 0220.707 to hook and remove the old disk at the base of the shaft and install the new one. Do not pull out the shaft, doing so will ruin the pump.

I'm not sure I understand. I put brand new drive units in each pump, 1 of the 2 still clicks. Are younsaying that in addition to the drive unit 6055.700 I need to replace another piece, a disc. Is the disc in motor housing where the drive sits? Ad that's why I need to pick it out

try moving the back magnet a little to the side.HHTH

There are two possible causes of a click, a loose or worn prop or the prop magnet slapping the back of the pump, the disk is essentially a shim that prevents this, last year they were upgraded to include a shock absorbing cup that will eliminate noise not solved by a new prop, the old one is a small black disk, about 1/8" thick and the diameter of a pencil eraser, it is at the bottom of the shaft, you need to hook it and pull it off the shaft without removing the shaft in order to replace it.

what happens if the shaft comes out? i went to check the pump last night to figure out the disk issue and when i pulled the impeller out, the shaft had come with it...i was able to get it all back together and the pumps still works...

It depends on the degree of damage, if the shaft can be pressed back in such that it doesn't easily pull out or fall out, it is fine, however, the pumps life will not be as long, the next time it pulls out, it is likely game over. The key will be to prevent the prop from binding to the shaft by regular cleaning. Eventually the shaft won't be firmly in the pump and will wobble, the pump becomes noisy and as it gets more extreme it won't run at all.

Hi Roger, as you described the pump started failing. I contacted the person i bought them from and he told me that the pumps I got were still under warranty. I asked him to get me a receipt or something, is there any info from the pump itself that I can provide you to check warranty coverage?

 

[rvitko]

Yes, it will have a date stamp so long as it was made after mid 2008. The date stamp is on the side of the polygonal motor housing under the front cover, the earliest ones from 2008 were week/year so you may see something like 1608, they later switched to a month/year code so 0808 would be August 2008, this was also about the time they switched to this date code method, the first 7 months of production had no date codes June 2007- Feb 2008.

This is a picture of the broken pump, don't see a date stamp, other than IP68? See pic.



The pumps were purchased in October 2009 from "champion", that's what the person I bought them from told me.

 

[rvitko]

Date is on the sides of that platform that houses the motor, IP68 is an international code which means "dust proof and water proof".

I reread the original post you made and the shaft pulled out by calcium binding it to the drive unit, this is an issue of maintenance and not a warranty problem. I am happy to work with you on a repair, but this would happen because it wasn't cleaned properly and the purpose of the warranty is to cover defects, not neglect. I would suggest sending it in, if I cannot repair it, we would discount a new motor. I am sorry, the thread title and starter led me to believe this was a post in regard to noise.

I understand, all I did was lift the impeller out to replace it, the magnet in the impeller must have pulled the shaft out.
Seeing as my tank broke this weekend, I can easily send the pump your way.
Should i get shipping instructions from the website?

Pump was sent USPS priority mail yesterday, you should see it by Friday.
Thanks. Fwiw, it seemed that the shaft could be re-adhered to the motor, it fits snug in the socket. I was close the mixing some epoxy, but thought it better to send in since I don't need it now. If it can't be fixed, let me know on the replacement motor.
Thanks for your help.

Will do, glues aren't a good long term solution, but if it fits snug, it may be possible to press it in with a hydraulic press and get it reseated.
