RD 3 Mini 50W O-ring
Hi,
I just dis-assemble my RD3 mini 50W return pump for cleaning, while i was cleaning I found an o-ring (OD 50mm) sitting on the sink, and i have no idea where i should put it back. Should it be place in the red housing or on the rotor? Thanks. 20180728_191849.jpg20180728_191858.jpg |

Thanks Slief, I think the o-ring that i mentioned is the one that sits on the red housing shown on the 1st picture. Thanks again.

Hi Slief, one more problem. I heard some straight noise after i assemble the motor, so i dis-assemble it again, both the rotating part of the rotor and the stator are good, without any foreign object inside. But when i rotate the rotor, i found that the flange can move not just axially, but also side way. I believed there should be a ball bearing / bushing inside that flange, so this kind of side way movement should be happened. Am i correct that rotor may have some problems?

It really was the buildup that caused the noise. After soaking the rotor in the white vinegar
, the motor is back to normal again. Thanks a lot Slief. You saved me hundreds of dollars, I was about to order a new rotor and also had my backup return pump ready to use. Thanks again. |
