Does the Griots use the same size wrench as the PC?

I am trying to swap backing pads and my wrench for my griots 6" seems too big. I slid it in on the opposite side of the counterweight and it seems about 2 sizes too large for the bolt in the middle. What am I doing wrong?"

I think they are all pretty universal, I know I grab whatever PC style wrench is closes to my hand and use it?

I'll be out in the STC for a few hours, I'll check and post back here...

The wrench supplied is roughly a 16mm. I can put it around the nut under the backing plate and it just spins freely. It is clearly too big. Is there something I am missing?

Yeperdoo...

Just used the Griot's wrench to remove a backing plate off all 3 tools...

Remember, don't over tighten your backing plates onto the free floating spindle, due to close tolerances the wrenches are thin and you can widen the jaws if you over tighten the backing plate like a caveman.

If you do ruin your wrench, you can find a replacement on the AG store here,

Porter Cable 7424 Flat Wrench

And it will work on all 3 style DA Polishers.

Mike, my wrench is brand new! It is not tight on the bolt at all (my griots in brand new as well). I can put it on the bolt and the bolt just spins loosely while the wrench is on it. Can you measure one of those wrenches? Mine seems to be roughly the equivalent of a 16mm opening. ( I held it up to a 16mm wrench in my garage).

Are you turning the wrench or the plate? I put my wrench on the bolt, then turn the backing plate to loosen or tighten. Seems like a silly question, but, I was trying to turn the nut at first, not the backing plate.

Also, my PC wrench is too thick to fit between the backing plate and the machine on the Griots.

In the picture above I pulled a wrench out of a Griot's 6" ROP and walked out into the Training Center and used it on all 3 polishers?

I can check again?

Kind of to build off of what t.4 Shelby posted,

If the wrench fits on the hex sided Free Floating Spindle Assembly that is correct and it should spin freely as it is "free floating" or "free rotating", you only use the wrench to keep it from spinning while you attach th backing plate.

I'm sure this is obvious but just to make sure...

Not sure what else to tell you, I can place the above same wrench on the Griot's Free Floating Spindle Assembly and take a picture of that too?

Do you have the washer between the backing plate and the Free Floating Spindle Assembly?

If so, then maybe I'm just using caveman technique?

I left my camera at the office, I feel like I am going insane. I can clearly see the wrench on the nut under the backing plate. When the wrench is around the nut, I can turn the backing plate with my hand and the wrench is too big and doesn't stop the nut.

Does your griots wrench have a hole at the end of the handle? I really think I have the incorrect wrench.

Long story short, I didn't get my wrench with my original purchase and autogeek just shipped me out a wrench, allen key and extra brushes for my griots and this has to be the incorrect wrench. I just can't get it to work.
