6025 noise after cleaning

[coseal]

i have some noise issues after cleaning my pump today. i think i might be missing a spacer as there is none on the shaft.

my other pump has a metal one that looks like it is maybe starting to rust? i looked in my 6055 and there is a plastic one and a metal one. i must have lost it when i took it apart. it was really quiet before the clean. also the prop tries to "jump" foward out of the motor block if that makes sense. thanks for any help you can give me

Did the shaft come out? The shaft should be permanently fixed in the pump. Older pumps had a white plastic disk and a stainless steel disk, newer pumps have a single black plastic disk.

no both shafts feel tight. one 6025 has a metal disc and the other has none. they are older ones i think. now my 6055'sboth have black plastic disc. i might have lost it when i disassembled but, i am not sure. was quiet before i cleaned it. now it is so loud it is un-useable...

Here is what I have seen cause this-

SS disk is free in the pump and grinding against the pump and drive unit.

The drive unit is worn so the bottom white plastic piece has come off.

You are welcome to send in the pumps and I will get them fixed up ASAP.
