After reading the post about the bearing failure on the C-7 fan hub, I was just going to take a poll who has had a similar problem or is this a more isolated problem. I know forums bring out people who have problems but would like to hear if there are more who haven't has that problem. I happen to be running a C-7 that was built in 2006 and is approaching the 50,000 mile mark and was wondering if I should be more proactive at getting it changed while I am not traveling. By the way mine does not have a grease zerk.:@

tinkerer,
This is NOT a known issue. As you have stated, we read on these forums, of primarily ones who've had to replace that bearing. What about the hundreds or, thousands of the motor homes with the C-7 that are running all over this country and NOT having any issues with that bearing. Not to mention that, the C-7 was installed in many, many kinds of trucks our there. Fire trucks, cement trucks, over the road trucks, local delivery trucks and more. So, while it is smart to be aware of the potential of failure of it, no one really knows or, can predict a failure, at any particular mileage.

It can go at 20K, 30K, 80K or, anytime in between. We presently have 62K on our '04 Itasca Horizon 36GD with the C-7 330HP. Yep, it might be time to me to think about it but, it may go to 80K or more, no one knows. And, as Brett indicates, you can order up the older style ones that were fitted tot the C-7s predecessor, the 3126 version CAT. Then, just make sure you do lube it, every now and then. Good luck.

I tend to disagree with you. When we were researching for our coach purchase, it became apparent to usthat this was an issue with early 2000 C7s, enough so that we looked to coaches that didn't have the Cat engine. There are lots of threads on all RV forums about the fan.
