    Everything was finger tight. Odd. Maybe the big flux in temps lately lossend things up

    Mine started making a lot noise. Kind of a laboring and squeaking. I loosened the screws that go into the center brace rod that goes between the brushes. Noise is gone. Don't know what would cause it to become to tight. I had never touched them before.

    I never believed in Santa Claus, but I have come to expect Murphy has evil little minions.

    I forgot to tighten things up. I need to do that in the morning before I start my day of abuse and pain.

    The gears are plastic, ZERO need for grease and it won't keep them from wearing. The gears go when you seize the brushes all of the sudden by running over the cord or a spotting rag etc. Normally it's just the one gear that will strip.
    Grease is the last thing you want dripping out of a CRB.

    You can use a hack saw or grinding disk to cut a slot for a screw driver in the screw head. Sometimes pliers work.

    You should be able to get hex head screws at local hardware store to replace them. Worse comes to worse hit them with a chizel and use pliers to get get the screw out.

    Or send it in.

    But get get hex cap screws to replace the Phillips.

    I still say it wasn't meant for residential carpet but only low level commercial. Too much stress on the gears etc.

    Maybe a little more but even on commercial it pulls down pretty hard.

    Keeping crud out from under the bearing cover is key I think. That's why it needs the hex caps so it's easier to maintain.

    No room to swing a hammer and the sides can crack. Granted I wailed on mine but I did crack it.

    Easier to pop the heads off the screws. The shaft will screw out easily unless it's been in there a long time and is corroded.

    Using the right screwdriver helps too. Use a #1 Phillips or smaller.

    with you on using proper fitting tool/bits
    be it hex, nut or Philips

    but pretty sure you mean #3 phil head??
    Only place #1 Phil head belongs and should be used is on the plastic battery lid on kid's tiny toys

    going "smaller", ain't the answer

    If the screws are steel in an aluminum frame, they have corroded.
    Replace them with stainless. Larry is exactly right with the impact driver, it takes a momentary shock to break the corrosion.

    Barely any stress at all if you lubricate the carpets sufficiently.. the CGD is just as much stress, it pulls more so with stiff brush.

    I have been running Whittakers and Brush N clean units for 18 years. Have owned over a dozen of them in all that time we have had one stripped gear and that was operator error. Tough machines

    One way to save the gears and save the motor from overheating is to just tip the machine slightly on end when starting it.

    It pulls the brush out of the carpet and lets them come up to speed before taking a strain.
