PC 7424 dead, what is a good replacement?

[marvinsdad]

I bought a PC 7424XP kit from Autogeek quite a few years ago...in 2007.
I use it to buff out my car really well once a year and the occasional detail on the wife's and some touch up throughout the year. It wasn't heavily utilized.

I noticed the last few times I used it that it would get hot and smoke...I would let it cool down for a while and continue to use it.
It finally died a couple weeks ago so I took it to a Porter Cable authorized repair shop. They kept it for the past couple weeks siting they were waiting for a part. When I went to pick it up they said it was un-repairable...because there are no parts available.
It feels as if the motor is locked up. When plugged in, you get a hum, but no turning no matter what speed setting you have it on. Manually turning the shaft does nothing as well when turned on.

Two Questions:

1 - Is the PC 7424xp from 2007 indeed un-repairable?
2 - What would be a good replacement...unsure if I want to go back to a model that died, unless they have made some major changes to it.
I read a few threads when trying to diagnose the smoking that there were a couple models that people were suggesting...one had a lifetime warranty (that sounds good about now).

Thanks for reading, appreciate any suggestions or help.

I'll take a shot at this.

I assume that it is indeed repairable, that every part for this Machine can be bought online.

The big question is, at what cost? I'll guess and say the main Motor is probably the most expensive part of all

Just to comment...

The XP version was introduced in 2009.

So if you purchased your Porter Cable in 2007 it would have been either the 7424 or the 7336.

The XP is the upgraded version of these earlier two models.

I'd recommend getting either the newer version, the Porter Cable 7424XP or the Griot's Garage 6" DA Polisher which is the Griot's version of the PC.

You got me, I was trying to get the "porter cable 7424 hd-plus" - I think basically it had a different counter balance and maybe a longer cord. But apparently I ended up getting the vanilla PC 7424. (now that I have looked back at old emails). Sorry for the confusion.

I haven't used a Porter cable with a 5 inch plate in a pretty long time.

I used it with my cousin teaching him, and I couldn't believe they night and day difference between the griots 6 inch and then pc7424xp

Saying the griots has more power is a under statement, seriously speed 3 on the griots is like speed 5 on the Porter cable .

On the PC speed 1-3 Is virtually identical, you even have to spread wax on speed 4 for it to properly rotate.

4-6 on the PC to fix paint.

If your not looking for a major upgrade I would go with the griots 6 inch.

I forgot how beastly that tool really is

Lots of "obsolete-not available" parts when I look online. So guess it is dead.

Based on your experience and apprehension about possibly buying the same problem, i would get the Griots machine. Lifetime warranty as well.

Another vote for the Griots DA

Another vote for the GG 6". Lifetime warranty. Work great with a 5" BP. More power too!
