Question about Riccar Vacuums
Vacuum noise increased significantly...still functions...slight burning smell. Same conditions with belt/brushed removed...certainly seems motor related. Can/should I DYI the motor replacment...looks like a replacement available form sub-$100
I am looking for a new motor for my 8920 Ricaar Vacuum. Can you lead me in the right direction. I can put it in my self. I replace them before. I used Ricaar for 25 years. Love them

SOURCE: burning smell
Unlock the sweeper brushes and take them out. on each end is a cup bearing and should be free of debris.
then check around and under the belt and likely there is debris wrapped around it.
the post is getting hot as your pulling too much of a load.
though if it continues the motor may have a bad set of motor brushes (inside the motor) or bad wiring (kinda unlikely).

Hi! Highly unlikely that you need a new motor. Highly likely that you need new carbon brushes. The smell is caused by excessive sparking between the worn brushes and the copper commutator segments. Most carbon brushes (and from memory I suspect this includes Henry's) have a copper wire buried in their last few millimeters, and you really need to change them before that becomes exposed. The longer you run it like this, the more likely you are to damage the commutator, so change them sooner rather than later. When you change the brushes, you can smooth off the commutator with very fine abrasive paper (the objective is to smooth it, not scratch it!), and then blow all the dust away (or **** it away if you have another vac, of course). Incidentally, you don't say if you are using a paper bag in your Henry. Some people, because the top-hat filter is so good, try to manage without a bag. This is false economy! You should always use a bag. I hope this helps! I value feedback, so please remember to rate this response.
