C-7 fan hub bearing

[tinkerer]

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.:@

If I had to change it, I don't know if it's possible, but I'd look at installing a greasable bearing with a hose that goes to the bottom of the engine to grease it.

Bill,

Yes, it can be done. Just make sure to purge all the air from the hose before screwing it into the hub. If you have, say, 5' of AIR in the hose, you could blow the grease seals and still not know if you have grease going into the bearing.

I have about 45k on mine with the original bearing (sealed/no zerk design) and have had no issues. I do remove the belt and check the bearing at least once a year for excessive play and drag.

I will admit this is the first I've heard of this as our Cat had the fitting and we have a Cummins now.

Having said that, if this is a known issue I'd sure be taking care of it at home rather than on the road. I'd a lot rather work on stuff in my garage than on the side of Rt 95.

Just read on another forum this morning where someone had a failure at 49k miles and cost him like 2k for repair. He said Cat gives that a lifespan of 40k miles. If I had that I certainly would replace it.
