That was my goof, the dia should be 6mm which I think is still too small. I also though of a mod, but with anything you modify especially propulsion and steering you need a long yardarm if anything goes wrong. The bolts I proposed are equivalent or exceed a grade 8 American fastener. No mod would be made, only improvement to a bad situ. Not sure the flange with tapped holes can even take much more diameter. FL should come to the table and make a proper modification they will stand behind.

To all of you who have been following my tale of woe, I submitted a formal complaint to NHTSA awhile ago. Wish I'd learned to do this earlier, but I needed to hear from others before I proceeded. Thanks to all of you. The web site I submitted on is https://www-odi.nhtsa.dot.gov/VehicleComplaint/index.xhtml.

Don't know if you can add an endorsement, but thought you'd like to know where it was submitted. The text of the incident is as follows:


At about 31,600 miles on my RV (2009 Forest River Berkshire mounted on a Freightliner chassis with Cummins 350HP engine), the engine suddenly overheated. During repair at a Freightliner facility, three of four retaining bolts were discovered broken on the fan hub mounted on the back of the engine; the fourth had backed out several threads and the fan tilted into the shroud and seized in place. Freightliner repair technician stated their facility had made several repairs on Cummins/Freightliner chassis RVs; the failure occurs with some frequency; the bolts and design of fan hub appear to be inadequate for loads applied by the serpentine accessory belt; and that failure of all four bolts could shatter the fan blades when it seizes in the shroud resulting in shrapnel damage to the radiator and severed electrical and fluid lines. Further consequences could include a need to quickly exit traffic flow to avoid becoming a collision hazard. From my understanding, the fan hub, fan, radiator and other accessories are added by Freightliner to the Cummins engine during chassis manufacture. Repair requires considerable and expensive removal of engine accessories. Use of this Cummins/Freightliner chassis configuration by other coach manufacturers is unknown. Technician on my repair drilled and tapped a fifth bolt to strengthen the fan hub. Online forum inquiry and interest from other owners suggests similar experiences. One other owner learned that Freightliner is aware of the problem, that they have no recall but they have a five bolt fan hub for purchase that evidently addresses a load failure problem with the four bolt design.

That is still less than a 1/4" bolt, 6mm=.236 and I would still try to go to at least 5/16" gr. 8. 5/16-18 root dia=.2403: 5/16Tap drill F .2570.

If it will take a 6mm, it will support a 5/16.

Correction and Update

Two things: (1.) I earlier stated that I sent my complaint to Good Sam's Club Hot Line. I was wrong. I actually sent it to Motorhome's Hot Line; and (2.) I also submitted the form for a vehicle complaint to the agency that was referenced previously. Perhaps if others follow up, we may see some results.

I just spoke with the NHTSA and they told me that I can't file a complaint until the I experience the problem. They then told me to report it to the Federal Trade Commission (1-877-382-4357), which I did. They in turn told me to file a complaint with the New York State (where I live) consumer protection. I am in the process of going to their websites and filling out their forms. If anyone else decides to go this route, the person I spoke to said to emphasize that this is a real safety issue where people may get seriously injured should this fail (either by shrapnel from the shattered component or by causing an accident). Also, I said that I contacted Freightliner and that they told me that they had a redesigned, 5 bolt hub available because they know about this failure. I told the FTC and NY State Cons. Prot. that Freightliner wouldn't repair this under warranty until it failed and if I was out of warranty at that time, I would need to pay for the repair. He said to make sure that I report this fact to them. He also said to detail what remedy would be acceptable to me, which is of course, for Freightliner to repair this under warranty before I experience the failure.

Hark, I agree that the more that register their complaint, the better chance of getting something done.

I don't know if the problem affects me or not since my my chassis was built in late 2010. I would probably be a little embarrassed if I "raised hell" over a problem that it later turned out I don't really have myself.

I plan to have the technician take a look at it next time I'm in a FL shop to see if I DO have the problem.

Boowho??

Hawk/Hark,
How long did it take Freightliner to make the repair to your coach? I am considering having it done on my next trip.
Thanks,
Tom

About 4-5 days.

Tom,
It took about a little over a week to get my RV repaired, but there were a couple of weather delays. Count on 4 to 5 work days. I was charged for 19 hours labor.
Regarding my submission to NHTSA, there was no response from them as to whether it was even received. I'm guessing it enters a black hole of statistics until enough similar complaints surface. No telling how many that might be. I'll look into an FTC submission as you did; sounds like a good idea. I live in Oklahoma, so I'll see if they have a process similar to New York's. I'd be interested in any feedback beyond what you've already learned.

Thanks - HD

Nhtsa

Hawkeye Driver,

I followed your advice and filled out the online form to the NHTSA. I filled out the form on either Friday or Saturday. Believe it or not, I heard from NHTSA (Tom Bowman) already on Monday. I filled him in on exactly what happened to me. He informed me thjat the emphasis on his agency is TRAFFIC SAFETY, SO YOU WOULD HAVE TO EMPHASIZE HOW YOUR PROBLEM COULD IMPACT ON YOUR SAFETY OR THE SAFETY OF OTHERS. He told me that he had never heard of this happening to anyone else before! Perhaps your complaint did not go through. Tom told me he will first contact the manufacturer (Forest River) and then the Chassis folks (Freightliner). He then said he would get back to me with his findings. If you send me a private email, I can provide you with Tom's phone number.
