View Full Version : Life Expectancy of the PC

Feb 28th, 2005, 11:34 AM
Here is a question I have never seen being asked before. What is the life expectancy of the Porter Cable DA polisher? I've had mine for 7 years. I only use it on my car and sometimes other family members' cars. It seems very well built compared to cheaper orbitals so I get the impression the life span is very long!

Lowe's has them on sale for $80 and I was wondering if I should get another one. Mine works fine so it may be unnecessary to get a backup.

Has anyone ever worn one of these out? I have never heard of it.

I know I've worn one out as has 2hotford, mostly an internal bearing problem. Starts to make more and more noise while you're using it and vibrations increase. I worn the electrical cord to the point the polisher wouldn't run unless the cord was jiggled all the time.

They are well built, that's for sure.

I figured if anyone wore one out, it would be you with all those weekend clinics and multiple users. Are the bearings replaceable or is that option not cost effective?

Mine is still going strong. It only vibrates when the speed is set to 6.0. And I just read yesterday that I'm not supposed to be doing that. I only run it at 6.0 when using #83 on stubborn scratches. At that speed and with a little bit of pressure, it actually generates a slight amount of heat. Almost works like a rotary. Very effective for swirl removal and the Meguiars pads hold up just fine. I realize this is something I shouldn't do on a regular basis though.

Every part of the machine can be replaced. This website has a complete breakdown of the PC as well as all of the parts.http://www.toolpartsdirect.com/cgi-bin/schematic.cgi/portercable/7336

Hmmmmm.........I wonder why everybody's Lowes store has them on sale except the Lowes in my town?:wall:

As a matter of fact, does anyone happen to know where I may be able to find an add stating their Lowes store has the PC Polisher on sale? Maybe I can use it as leverage for my Lowes to sale it for $80.

The closest Lowes near me is... Piscataway (isn't that where Meguiars hold their clinics?) It's a 20 minute drive for me. And I went there once and they still had it at $100. Wasn't too thrilled.

But, I recently got a new PC7424 with an extra pad (wife ordered, didn't know the pad wasn't needed) for under a $100. So I beat the store's price and certainly beat the Lowes.com price which needed tax and shipping.

Amazon.com was the name.

We use and abuse them and they run forever. I have three. Two in use and one back up. I replace them every five years if it runs good or not.

I just bought one at lowes for $100 and will be ebay-ing the old one soon.

You can always wait for Mike to put THE G-100A on sale here. I bought mine and it came with the backing plate and 1 polishing pad for $150. The best part. LIFETIME WARRANTY. :xyxthumbs

Do you know when the G-100 will go back on sell???

Did anyone of you ever send in their G-100 or PC for service?

I'm in Manila and I'm concerned about it's maintenance regimen (if any). They're not locally available so I need to import. :(

I'm bent on getting one but I may need to order some parts that may need to be replaced.

The brushes for the motor are user replaceable and you can get them from Porter Cable.

I never got mine repaired; I replaced it with a new one. I figured that it gave me excellent service over the years. Plus, if I wore out a part, other parts must be showing wear as well.

Truthfully, I would not worry about spare parts etc... The PC is a strong tool. But like anything, will wear out with tremendous use. However, for most people, I really doubt that would happen in many many years! :)

Thanks for the input guys. I'm still curious though if detailing masters like Scottwax, Jimmy Buffit, Deltman, Superior Shine, etc. who use the PC more than any of us need to do any maintenance for them.

Ouch....well...I am not sure about the Masters, but I never had mine serviced, though it was used for over several hundred hours of use.

As a master (:D EGO BOOST), LOL!!
I do nothing in the way of maintenance for the PC. It is a tuff tool. We use ours at least 4-6 hours a day 5 days a week for a good 4-5 years with not problems.

They fall out of the van, off ladders, get wet, dropped and still run strong.

No offense meant 2hotford! ;)

I had you and Mike Phillips in mind too but both of you already gave your valuable input. :D Thanks for the extra encouragement though.

Now I can rest assured that the G-100 / PC will give me years of faithful service. Thanks everyone! :xyxthumbs
