Griot's Garage 6 Gen 2 DA accident

[originalgoods13]

Yes, this one was bought back in 2011 and it had the recommended speed setting 5-6 for polishing and I have religiously followed that since.

I am glad no one got hurt and it flew away from the vehicle and into the garage door.

It separated so fast that I did not even see it fly off, I just heard a loud bang

The only tell-tale sign that I saw was the nut was easier to access with the wrench compared to the new GG, I would assume that that piece was slowly pulling away and separating itself off from the rotating body/bearings up the failure.

Notice that backing plate has score marks in black from the shield cover of the rotating assembly

I'm glad YOU didn't get hurt!

My Gen 2 also went flying on me and GG PROMPTLY replaced it with a Gen 3, which I agree with you was night and day. Mine sheared off at the stem and the counterweight just went flying along with the backing plate

for anyone who has or used both the 2nd and 3rd gen GG6, are the GG6 3rd gens as or more powerful then the 2nd gen?

[MarkD51]

Would it be correct to assume-guess, that it appears that machines like the Griots, and PC (and perhaps others in this genere) rely on simply a press-fit of the Backing Plate Arbor Shaft?

If so, then my take is that in essence, every one of these machines is a ticking time bomb, that it's not if it will or will not happen but when? And at what cost?

Me, I surely wouldn't be worried about the machine, but worried about vehicle damage.

Seems to me a poor design, where perhaps something as simple as a C-Clip or another minor design change-upgrade may have prevented such?

I don't think I've read of such yet occurring with machines like the Rupes, or Flex?

Did you notice if the inner race of the ball bearing assembly turned freely? I wonder if this was caused by the spindle twisting inside the inner race because the bearing was tight.

[jakeru]

Probably caused by ball bearing failure in the eccentric spindle.

These bearings have tough lives, as the high centrifugal forces of their eccentric motion can tend to sling out the grease past the rubber seals. Once all the lubrication is gone, it's just a matter of time until the bearing freezes (no longer spins). When the bearing is frozen, the steel shaft of the eccentric spindle can spin against the inner race, resulting in a "spun bearing" type failure as your picture illustrates - with metal-on-metal wear.

Is there a serial number breakdown for each generation of GG6 polisher? (Or some other easy way to differentiate?) I think mine is a Gen 2, but am not really sure.

You can tell by looking at it.

• First generation
• Second generation
• Third generation

the 3rd gen, which is the one currently sold is this one below...


2nd gen is the one without the rubberized material on the top of the head, ergonomic moldings/placings on the body and on/off switch on the top...


you'll also notice that on the 2nd gen GG6 that the sticker
on the side reads polishing 5-6 and waxing 3-4, where as
on the current 3rd gen it reads polishing 4-5 and waxing 2-3...

some have also said the 3rd gen isn't as powerful as the 2nd gen,
but GG assures that the only thing different is the exterior and the motor still remains the same...
