AC clutch fell off

[SidneyW]

Has anyone had their hub fall off the front of the AC compressor? Mine did. Found on another site where it is very common. The bolt that holds it on breaks off. The AC quit cooling,pulled over to check it out. I heard a noise ,slid under truck,and find the hub resting against shroud. Went to my local AC shop and they said also very common. Something needs to be done to correct this crappy design. Truck has 44,000 miles.

I have never seen one fall off.

I don't know where you're at, but I've got a good used compressor off an '03 that you can rob parts off of or have the whole thing.
I've never seen one fall apart on a Dodge. I've seen several fall apart on Toyotas, off highway equipment, and medium duty trucks.

I am down in Dothan,Al. Thanks for the generous offer. I believe they are diff. I am gonna try to tack weld it back on. Don't feel like spending 800. 00 on a . 49 cents bolt.

I put a lot of miles on an '06 very quickly while I was transporting trailers. Mine developed a rattling noise at idle or low speed . . . at about 200k miles IIRC. When it was investigated we observed that one of the three rivets that held the clutch together was missing, one was stretched and loose with separation imminent, and only one was holding it in place. The compressor and clutch were still working fine but catastrophic failure was just one trip away.

I've been on this forum since the beginning of third gens and never heard of one just falling off. I don't believe it's common at all and if Sag2 hasn't seen one then it MUST be rare.

You know, I almost feel like some of you are almost calling me a liar! Why would I make something up like this? I have better things to do than that. Go on Cummins forum and search it. There are over 13 pages of this very problem. I am not the only one this problem has happened to. When I walked into my local auto air repair facility with my hub in my hand, they immediately recognized the issue before I ever spoke a word! Thanks anyway gentleman.

Not saying you are a liar, we are saying we have never seen it, guess we are all just lucky.

From what I have been reading, I believe it's around 2008 and 2009 year models. I may be wrong about that though. And around 40 to 50 thousand miles. I certainly don't want to say something that isn't dead on with accuracy !

OK, I read some of the posts at Cummins Forum. The only thing I can say is everyone that subscribes to that forum must have purchased all the bad trucks. I could not believe that the disparity could be that large. So off to the parts book, looked up clutch and compressors for 2008-2009 trucks. The catalog I used did not have just diesel listed, so the part numbers I looked up are for both gas and diesel trucks. And they fit more than the model years I looked up. Here are the results. I will list the PN and the average weekly demand for each for the nation.
Pulleys
5183899AA 1
68034537AA 0
Pulley bolt
68025879AA 0
Compressors (reman are R... . )
55056336AB 5
RL056336AC 5
RL111436AB 4
55111436AB 4
R5056336AC 6

So make of it what you want, but if half of the compressors listed above are gas, and half are diesel, the 6. 7 trucks go through 12 compressors a week, and one pulley every other week, and no bolts. I do not know how many 6. 7 trucks there are on the road, but the failure rate has to be miniscule. Again not questioning the other Forums validity, but the numbers just don't support the allegation that these compressors, clutches, or bolts are junk.

I have never run across it either. I do replace a compressor now and then but none that have fallen apart

I have to say that CF is laughed at quite a bit,the more time you spend there the more jokers you find.
An example would be last week I saw a poster giving advice to a member that his code is often caused by an injector wire coming off the injector. For background those that have never seen a CRD injector the studs are fairly long and the nut is captured on the harness. To remove one you MUST lift the nut off the stud after the nut has been loosened. This advisor had his own thread going on how to make his truck run after an injector replacement a short time back. Go figure. .
If it is on the internet it must be true.

In defense of the op here if I hadn't heard the rattle at idle my compressor clutch on the '06 I had at the time would have fallen off when the last rivet failed, probably on my next loaded trip out of IN.

CF has gotten ridiculous, I still go over there but my rate of posting and reading has greatly diminished.

Exactly my sentiments

I replaced my AC compressor back in the summer of 2011 on the '05 because it quit "compressing" / cooling but the clutch was still attached and working.



I have seen the clutch fall off the compressor on a John Deere 6420 when the bold came out. Best luck we ever had was the bolt was laying below the pulley on the compressor mounting plate. Go figure.

Thank you Sir for your support! Never the less, this problem did occur. My truck is like brand new. 44,000 miles. It isn't a problem with the compressor or pulley or anything like that. It is simply the bolt that holds the hub on the front of compressor. It breaks off and the hub comes off. Simple as that. Very small metric bolt. I think 6 or 8 mm. About an inch long or less.

I'm trully sorry if my post came across that way. It was only my intention to suggest that the occurance was rare and not that it didn't happen.

I've had freaky crap happen to me too over the years!
