Problem: PC Split in 2

[eyezack87]

Posted in various forums btw, just want some input thats all :faint:



Well, I'm back you guys and I'm definitely not happy yet again. Yet another thread about my PC problems, in which my first one was about 6 months ago (Problem: Melted Backing Plates). I'm starting to feel that my PC is cursed or something because of all these unfortunate series of events .



Anyway, my PC is less than one year old and I take amazing good care of it. Never dropped, only placed down gently on whatever surface is available at the moment. At most, I have only used the thing 6 months out of the whole year I had it so age is definitely not a factor think.



Story Time! (I know you like these)



On Saturday, I was detailing a red 08 Volvo C30 for a client who wanted my standard 1 day correction package with my friend, Brian N, who was using his Flex. We were doing this Volvo tag-team style to make it easier on us. Thank god we did that since my PC decided to explode on itself 3/4 finished with one stepping the vehicle. That meant I had to finish up my half of the car with M105 and a foam pad by hand sadwavey



There is a rod that spins in the PC which ties to the counterweight and other parts which make the PC an orbital. That rod has snapped at the base for who knows what reason during the detail. As you can imagine, the backing plate (grrr) and the PC internals blasted out of its holder. Thank god that it did not hit the client's vehicle and I was only spurring the pad!



Now I am left with a broken PC and unable to polish anything (again! :grrr). Feeling sad and frustrated too



Pictures

(The pad is off center due to the force the whole thing hit the ground. Was perfectly center before it blew up :wow

Now for the REAL question...

Anyone else had this happen to them or hear of another person having this problem????

Thanks to Greg @ DI for trying to help me right now. Really appreciate it man :up

should be able to get and install replacement parts. have it up and running again in no time. looking at the parts diagram there is supposed to be a screw that holds that flange plate (w/ counterbalance) to the center shaft.. did it shear the screw?

I believe the the mfg. warns against running the PC when not in contact with the working surface. Is it possible that spurring doesn't provide enough resistance? I'm not blaming you but it would be good to know for future reference.

I didn't pull my schematic but it looks like a broken fastener to me. The problem is going to be getting the broken part out of the shaft, may have to replace the shaft which will be a bigger deal.

Screw? Iono, it could be the shaft. I'm taking it into the PC repair bay this friday so hopefully they can do it all for me

Interesting, I have never heard of this. I know quite a few people who spin dry their pads using the PC since they have a rotary but they don't have problems :shrug:

I'm thinking it is the shaft as well since it broke off right at the base where it meets the inner workings of the PC under the plastic cover. I would haphazard a guess that it should be an easy fix BUT, the counterweight and company got dented pretty good by the fall so I might have to get the entire assembly replaced by PC

Yikes man....that sucks! I'm actually considering putting mine up for sale. Not because it's a bad machine or anything, but I really don't have any use for it with two rotaries around that work faster and better at getting the paint work done.

That sucks. I've had mine for about 2 1/2 years now, and no problems what so ever with it. I don't like to spur on it, though. With the velcro backing, I'll take an extra 30 seconds to put the pad onto my DeWalt Rotary, spur it and then put it back onto the PC.

eyezack87- Yikes, glad there wasn't any damage to the car



FWIW, I don't spur my PC/Cyclo pads, I rub them clean after spritzing them with Meg's #34. And no, I don't spin pads dry with them or otherwise run them unloaded either (although I *do* do those things with my other machines).



I can't help but wonder if the pad size also had something to do with it it...that pad weights a lot more than a single sheet of sandpaper :think:



But no, I've never had that happen with either of my PCs and they've been through a lot ob real *abuse* over the years.

I'll prolly have a rotary soon due to this. Having a Flex sounds a bit...unnecessary lol

Well, to be honest, this was my first time spurring with a PC. It was a brand new orange spur thing too. Could be the off pressure combined with the rotation that caused the shaft to break off or something. We'll prolly never know :aww:

+2 to that. The customer was watching too so I couldn't blame it on the neighbors :nervous: lol



I just find it weird it keeps happening. The only real abuse I put it through is polishing wetsanding marks out, but that is still relatively easy on the machine :sadpace:

Bringing it in for service hopefully tomorrow. Also hoping that the guy can explain to me what went wrong :bigups
