I replaced the clutch for the first time in my 15 year old vacuum. Amazing how stretched the original belts were. New clutch is working properly. However, it seems to be working “too well”, if that’s possible. What I mean is that if I vacuum wall to wall carpet, all is fine. When vacuuming area rugs, I get the clutch ratcheting noise, signaling that the brush bar is jammed. Presumably because the rug is lifting enough to stall the brush bar.
Is there a break-in period to be expected for the new belts/clutch?
