Maintenance and care on PC

**anson89** · 05-21-2011, 05:42 PM

I think it's time I perhaps grease up the parts or give it a little TLC. I see the the wear and tear on my 7424XP and because of that, it's generating a lot of heat causing my pads to tear up as well.

How do you guys do this?

I've never touched mine, what does Porter Cable recommend?

You gotta get it oiled a bit. They recommend just dropping it off at a Certified/PC shop to get a few work done on it.

Not having a PC or ever having one a part I'm going out on a limb here but I would guess that it has sealed bearings on the armature so there won't be too much you can do to it other than replace them. But that's not to say that you can't take it apart and give it a good cleaning and lubricate what can be, that in itself should make it run a bit cooler.

My original is still going strong more than 10 years later. No real maintenance either ...

Bill,

I think that this is just another way that manufactures add to their bottom line. I've had mine for about 12 years and all I do it occasionally blow it out with an air gun and wipe down its exterior................I do not detail it!

Was thinkin' the same, but couldn't get my fingers and mind to say it correctly...LOL.

I have a 30+ year old shop vac that has NUTTIN' done to it (just normal cleaning) and it still sux like brand new.
