I think the "grinding" sound may not be coming from the brush roll, but rather from the motor unit.
If it is the motor making this grinding sound, here are two possible causes: 1. Dirt or debris in fan case. REMEDY: Inspect and remove. 2. Bent vent fan striking field screw. REMEDY: Straighten fan: tighten or replace field screw if loose. If you still think it's the nozzle - and you said you already replaced the belt and brush roll, then you may need to inspect the rug plate gasket for wear; if worn, order a new rug plate gasket (154881S). I hope this information will help you! ~Ben |

Some early Heritage 2 models were produced with the Extended-larger Heritage 1 nozzle So I don't think that would be the cause of the noise, Like Ben said try replacing the rug plate gasket, also look to see if the two locking lugs for the rug plate are tight and that there is no movement in the rug plate, some times the locks can bend slightly resulting in the rug plate not being tight against the nozzle.
Away from the nozzle have a look to see if the backing on the handle is screwed up tight, sometimes you can get a horrible vibration from this when the Kirby is running if its not done up tight enough. Those are your likely quick fixes, If your impeller is fine then you could be looking at something harder to repair like possibly the front and rear motor bearings. Craig |

If the new fan came with different hardware, ie. different or missing washers and gaskets, then you most likely installed the wrong fan kit. The proper fan kit would have come with the exact same hardware that was already in the machine,
Re using the old parts is not a good idea because they will wear out prematurely and may also have been contributing to the noise in the first place. |
