If I can''t find the exact OEM brushes for a motor (vacuum cleaner) at ceahp enough price, what are the disadvantages of substituting a generic which might be undersized? I don't care if it lasts only half or quarter than the original. Original lasted 35 years; so if the new only last 10 years, I would still be happy. Surely, it must be better than stuffing couple of magnetic disks there to force the brushes to make the contact again! That is what I have done right now. I have had few spare brushes from HF tools but the end caps are different and they will not fit. I am planning to go ahead and order cheap different size brushes from ebay and see if I can somehow fit them there. Can I grind the brushes if they are too long or that would create huge big mess with the carbon dust flying all over? Can the brushes have lot of lateral play inside the housing or they need to be snug fit?
I bet bunch of you have lot more experience with brush swaps on motors and I would like to hear from you.
