Lucky is the key word in your fan bearing failure. My coach with a 3126B Cat thru the fan into the shroud, busted it up, busted up the fan assembly itself. 1200.00 in repairs. I now grease my fan bearing myself and trust nobody I pay to do it correctly. Every 5000 miles.

Cat c7 fan bearing failure

Hi, probably a cat engine ? My 2005 phaeton had cat- c7 with 52000 miles when bearings seized and broke bolts securing it . No prior warnings or symptoms = engine temp light when belt got cut. No radiator damage . 17 hours labor and cornerstone warranty only paid 5 hours labor . No grease fittings . Good luck . Dean

$1,500 tow was due to you not having a ERS policy.
That $1,500 would have paid for over 15 years of a ERS policy.
In the next 14 years you could have had other problems that a ERS will be needed.

Not too late to get one now. One flat will pay for more then 1 year.

For the dealer to cover the fan cost.
Is it within the warranty period the dealer gave you on the buying date?
If not you are out of luck.

Did you tell the dealer that there was a vibration of some kind on the check out?
Did the dealer say he would take care of it.
Did the dealer offer to sell you a insurance policy on failed parts?
Did you turn down the insurance on parts?

You may want to think about getting a parts insurance policy now for future problems.
Don't forget the ERS also.

About the same for mine except mileage was around 50K (I think). No advance indications of anything going wrong until the bearing failed. As above the only damage was the fan bearing.

If you have nothing constructive to offer, and no direct answer to my question, is it really necessary to be snarky?

I explained twice why I did not write what my symptoms are. I'm a mechanical engineer. I want unbiased data.

I have some data now.

Triker56, thank you, yes I found vibration that the dealer explained away after the inspection as "idle is too low - these CAT engines need to idle around 800rpm, not 500rpm"

I recorded (audio) all of our conversations as well as the inspection (all three hours of it).

I think by the dealer increasing idle RPM a temporary correction was made to the failing bearing, thus reducing the vibration to almost nothing detectable. I was assured the idle was initially "set too low" and "the engine was cold".

I believed the dealer. I inquired about extended warranties and service plans, and was told to "go online and look for one" to buy.

Catastrophic failure occurred the second day I owned it as I was driving from Texas to Arizona. Dealer is offering $1000 towards my repair costs and that's all. I think he knew about the bearing (or at the very least, that something was amiss), I think that's why the coach was up for sale. I trusted the prepurchase inspection, thinking I covered all the bases. The plan was to purchase a service plan and roadside assistance as soon as I got home and had the means to do so. Perfect storm.

I have purchased AAA plus RV, as of last week, so all you guys' snide remarks about that are bouncing right off me.

I feel the need to reiterate, for those who don't have something helpful/useful to say, are you THAT old and miserable that you have to berate others in the forum?? Get a hobby...

Thank you Dean!

Vibration was my symptom. 148k miles (I'm guessing this has happened before, no way was that sealed bearing original to the coach). 21 hours labor estimated, treading water waiting for the final. # hours labor is more than the #hours I've driven the thing...

The reason the labor is high is they have to remove the rear radiators to access I would assume.lots of hours to do that. I had a cat 3126 ( c7) in my Winnebago and the bearing failure is a common concern on cat centered forums i followed at the time.
I never had a problem and don't remember any reported symptoms from others on the forum other than if you didn't lube the ones that could be ( some were sealed the replacements are not ) trouble was waiting As a matter of fact the sudden failure without warning was the concern
I would look for additional estimates
My opinion and that of many others evidently are that the dealer may or may not have known .. But you'll never prove it. What we do know is these things are great fun and very expensive to repair.
I was told a long time ago to set aside 10-15% of the purchase for repairs my current coach has met those standards ! :-(
Good luck

GearGirl !
Being a Mechanical Engineer You should know that we on here can't provide adequate (data) or educated answers to your questions based on assumptions without input and information on your coach. With that said let's move on.
If your problem developed in that short of time one would think you have a Legal issue with your dealer,You'll have to prove the problem pre-existed you may want research that.
On the issue at hand. If you in fact had a vibration at the Engine and discovered that the Fan Hub bearing failed and based on the year make and model of your coach, then Yes the estimated Labor to repair the problem is a legitimate number as Rear Radiator Coaches are extremely difficult to work on. When ever I read these stories, my first thought is that many first timers don't do enough research before purchasing a New or Used Motor Homes.
Please keep in mind that most all of us on here only want to offer assistance and provide support to You based on our experiences. If my prior comments offended you then I apologize and wish you lots of luck finding a solution to getting your Motor Home back on the road.
