Re: Help with my 7424xp
I have a similar problem with my 7424xp. The brushes are $6 apiece and you need 2. Just google carbon brushes for porter cable 7424xp. There are 2 models, type 1 & type 2, just look on the badge it says that very clearly. Mine was type 1
I have mine on order but they shipped to the wrong location or otherwise would have them installed already, go figure. Mine started to make more noise and the rotation was very inconsistent.
Just take off the 4 torx screws on the handle, it will split in half. You can see one brush easily, the other is on the opposite side. Didn't look tough to replace at all, just fiddly.
When mine finally arrive I will update you.

What happens if you plug it directly into the wall socket?

Great thank you! I'm ordering mine today.

Do you have the compression washer between
the machine and backing plate, just a thought.

Re: Help with my 7424xp
When my PC 7424XP was brand spanking new, it ran like crap at first. The speed would vary a lot, all on its own. I would set the speed control to 6 and while free-wheeling it, the speed would be all over the place. It would speed up then suddenly slow down, then speed up, then bog down again..... I put a backer plate and pad on it anyway and tried it again. Just as before, it was running really slowly and then all of a sudden it puked out a bunch of white grease from all the vent holes. It seriously blew grease all over the place. All over my apron, the backer plate, the car I was standing next too, etc... I shut it off and wiped up all the grease, cleaned up everything and then used a Q-tip to get the rest of the grease out of the 7424XP's vents. Fired it up again and it has ran like a champ since. My 7424XP just seamed to be way over-packed with grease at the factory, so much so that the machine was bogged down by all the grease. Once the machine had flung it all out the vents, it has been fine since.
Could this be the OP's problem?
Has this happened to anybody else? Is this common?

Good advice.
Although MarkD51 has great mechanical advice in some above posts, and he is most likely right, I'd first plug the tool into a wall socket like dlc suggested. Just to eliminate the simple & obvious. A bad extension cord can deliver erratic voltage which would also make the machine act as you described.
It is no coincidence that man's best friend cannot talk.

I have not had a chance to use it since then, but I plugged it directly into the wall and it ran smoother. I did not leave it running long, but I have a car to detail next week and I will post an update.
Thank you for following up!
