Ugh...the never ending PC saga

OK. I have my PC 7424, have my counter weight on order, and picked up a W64DA backing plate and a few pads.

Problem now is I recall that the PC didn't have a bolt in the mandrill (I am at work now) and I just picked up the backing plate and it doesn't have a bolt either.

Sooooooooo......how do I go about attaching this puppy now?

If I have to get an adaptor bolt I am having visions of the backing plate flying off anf the bolt screeching across the finish on the car.

Help!:nixweiss
 
I called Meguiars support line and thier rep said it is supposd to come with a bolt in the backing plate.

Either there is two versions or I just got hosed and will be returning the backing plate.

I hope all this effort will be worth it.:confused:
 
Only rotary buffer backing plates come with a bolt. Plates for orbitals screw into the machine and are held in place buy the factory installed clamp style bolt, that's why they give you a wrench.



Put on the new plate the same way you took the polishing head off.
 
Showroom,

I probably shouldn't post until I get home to look at it (A type and too impatient) but I thought the 7424 pad had a bolt in it?
 
Nope. No bolt. The center shaft of the PC screws into the pad, and there is a retaining nut which spins around and has to be held by the thin wrench they provide you with you that it butts up against the back of the pad.
 
Yep, I have a Meguiars backing plate with a bolt. The backing plate screws into the pc and the wrench they provide is to keep the shaft on the pc from spinning. I just place the wrench on the pc, spin the backplate on and tighten.



There are probably a variety of plates on the market. CMA, griots, meguiars, PC, ect.



PS, if anyone is interested I can take a picture and post when my new digital camera arrives! :D
 
Sam,

I pic would be great.

Maybe I wasn't clear but by bolt I meant a male end.

I got back to my car the package was actually a labeled as a W64 not a W64DA and clearly states for a rotary buffer on the packaging.

They gave me the wrong part- partly my fault for driving away and not checking.

I think paul e is right - so by bolt I meant male not female end and it does screw into the bolt on the PC.

Sorry Showroom but you will have to supply a pic to convince me otherwise.

The guy at Meguiars was right.
 
I can post a detailed picture on Friday. The link that was posted above shows the threaded stud, but it is difficult to see.
 
If you mean does the backing plate have a stud, then yes it does. I thought you ment a bolt that actually holds the plate to the spindle from underneath like a rotary buffer plate.



So yes, you backing plate should have a threaded stud on it.
 
Ok, I think we resolved this, but I promised a pic so here it is:

Yep. That would be the "bolt" I referred to.

It turned out that the guy gave me a wd64 istead of a wd64da.

Thanks for the pic regardless!



I almost all of the basics to get going except for the 6 counter weight - and patience isn't one of my virtues.

I will bug the girl at the Porter Cable warrenty parts source tomorrow.:wavey

I will also get a few more pads from the group buy.
