Ok... So I am in the middle of my winter prep on my final car of the year, and this happens. All of a sudden spindle in the head of my PC comes loose and drops out. Luckily it didn't hit the paint.

A little background.
- The unit is 1-1/2" old. I received it as a birthday gift back in August.
- The unit has only about a dozen uses on it.
- I am very careful to make sure I am not overly hard on my tools.


So my questions are this.
1. Has anyone else had this happen before?
A. If so what did it take to fix it?

2. Is there a warranty to cover this? My PC didn't come with a warranty card or anything.

This might be the first time I have ever seen an issue with the PC polishers breaking. I hope it was purchased from AG.

Dave, This did come from AG. So yes I'm very lucky.


Dwayne.. I want to thank for for being available to take my call and answer my questions. Thanks for the help.
 
I'm curious as to whether there was a type of circlip or snap ring groove that broke off of the spindle assembly or if maybe it was a pressed fit part that may have been cut just beyond it's range of tolerance and consequently fell out. I am glad to hear that Dwayne has you straightened out with it. Just another reason to stick with AG.
 
Looking at a parts breakdown of the 7424 it looks like its just pressed in.

The assembly in the parts breakdown actually shows the spindle and bearings as all together (sold as an assembly)

As mentioned it could have been the odd mix of tolerances or who knows.
 

I've never seen that happen with a PC. From just quickly looking at the pics, the spindle seems to be pressed into the bearing.




 
As we know ANYTHING can break at anytime (usually when we need it the most) but that is why I will only buy from Autogeek...simply because of the top notch service people who are at Autogeek. Thanks Dwayne for being so willing to keep your customers happy..no surprise though as you have been great to me as well. My PCXP is doing well now..but I will be aware of that possible issue in the future.

You are correct. I looked up the parts diagram before I posted. I can press the "sleeve" back in and it seems like it would stay but after starting the machine back up it came loose again.
 
Thats interesting, in the other thread mentioned it looks like something was broken/sheared off.

If anyone has one that has broken I would be interested in taking a look at it, possibly repair it
 
How cold was it when you were using it? The tollerances may be off, but what I would like to know is if you warm it up to inside temps if the pieces become tight again. Im wondering if its a case of metal expanding and contracting due to temperature.

I was working in my heated garage so it was some where in the 55 - 60 degree range. Looking at the diagrams and the broken part it did seem like it should have been a simple press in fitting. I took the PC inside and pressed the spindle back into the sleeve and left it there to warm up. But even after an hour or more the spindle was still loose and would pop right out.
 
The temp shouldnt matter if everything is the same temp (within reason)

Now if you froze the inner part, and heated up the bearing, then you have created a greater difference in the dimensions that may allow a slip fit.

We do things like that at work all the time. We have a small 2 stage freezer that goes down to -100 farenheight, and also an induction bearing heater.

With those two items you can take a bearing that normaly is a very tight fit and it will just drop into place.

FWIW the bearing like in the PC is a sealed bearing and is not used in an application where it would need heated up
 
Just found this pic nosing around. Certainly looks to be pressed into place.
I see no kind of retainer.

This just happened to me today, but the inside looked worn down.
 
If you need this to work now get some LocTite 271. This is specifically designed for securing shafts and bearings in place.
 
I had this happen to me recently on my UDM.

It looks like the snap ring broke, and now the inner piece that the backing plate screws into can slide around. The entire backing plate actually flew off while I was buffing - luckily I did not have the counter weight smash into the paint (I had a backing plate snap before while buffing my brand new $70k BMW Z4...counterweight proceeded to gouge the paint down to the aluminum hood...i literally felt like crying).

I believe there's a groove where the snap ring can slip in to secure everything. The question is - what size is the snap ring and is this assumption correct? Does anyone have an exploded view parts diagram for the original 7424? I only see one for the 7424xp on PC's website.

That was helpful - I determined the UDM (at least the version I have) is not a PC 7424 clone. The counter weight design is not constructed in the same manner.

After googling some more, it appears that it is a c clip that came apart. Looks like a replacement c clip can be purchased at any hardware store so I'll see if that fixes anything.

First time using PC, think it's broken?
