You start out with a 1" shaft and end up with this, you heard something!
Every customer you take for granted today will be someone else's tomorrow.
I fixed this one last year
also was told there was no noise
2-1/2" shaft 10 feet long with 1-3/8" bearing on each end
I had a new end with a collar made and attached it to the old shaft since replacement of the old unit was impossible.
This is what i have running through my head when i hear
"nobody touched it"
"It worked fine yesterday"
"We never had a problem until now"
"i always change my filters"
Call B***Sh** Man!
