If you want to keep them working as long as possible, change the brushes on a schedule.

Just found out my factory motors are model # 8055EM. They're $90 on amazon. KR has the motor listed in the link for $30. Is the 8055 a better motor? Which one would you go with?

What do you guys typically clean the inside of your vacs with? Is there anyway to remove the odor that comes from around the hose when the vacuum is started?

The VMK19 is the motor that J.E Adams uses, it's made by Electrolux. It's an OK motor, someone gave me some to test about 5 years ago and they are still running today, just keep the brushes changed. I'd buy 3 motors along with brushes and change the brushes on the other motors.

When we get bad smells from the vacuum we suck up some "Love my Carpet Lavender Dreams Carpet & Room Deodorizer" from Dollar Tree after we clean out the vacuum, some times I'll toss in a air freshener into the clean out.

Each of our location has 2 sets of vac bags. We ask for them to be cleaned quarterly. Guys remove them and put on the spare bags and take the dirty bags into one of the bays and was them down with HP. Once those dry they go to the next set of vacs and do the same thing.

Randy, would I need to replace the 2 working motors with the KR motors? I’ve read on the forum not to mismatch motors.

I would. Buy 3 new motors and some brush kits and you'll be set. How many vac's do you have? I'd buy brushes for all of them.

I only have 3 vacs each with 3 motors.

I've seen mismatched motors many times, doesn't seem to cause an issue but the vac is a lot noisier.

Rfreeman,

Count me in ... along with Noob ... when it comes to finding out your notes on your Vacuum Suction Readings ... that you mentioned in a previous post.

Update: I changed all my brushes but am still having issues. The video below shows a motor that the fan start running and slowly ramping up after the other motors have already been activated. There is also little to no discharge of air from the motor out of the motor shroud. Do I have a bad motor? Any other ideas?

I would have to say you have a bad motor or there is something obstructing the flow off air into the motor. I'd replace the motor.

I think that motor is turning backwards, which tells me it isn't running at all. It is being spun by the suction from the other motor, hence the ramping up.

Noob,

You need to look at motors running with the door open. Otherwise suctions from good motors will cause bad ones to spin.

Exactly these. I can see it turning backwards when it comes on. More often than not, if you let the brushes wear all the way down it will arc and burn the commutator which ruins the motor.

Try slipping a piece of cardboard under the bad motor and see if you can tell a difference in the suction vs the ones with all three working.
