As for the Zerk fitting in the fan bearing, the 3126E version was pretty much the last of the zerk-fan bearing motors. And, although there's a tad bit of controversy about the actual change-over date, the last of the 3126E engines, in the Freightliner chassis, were installed about July to August of '03. Then the C-7 came along and, with that, the permanently lubed fan bearing. Our '04 Itasca Horizon with the Freightliner chassis has a chassis production date of Sept '03 and, as stated, is sporting the 330HP C-7.
That's what I thought about the change over, but within the last month someone on this site posted that their C7 had a zerk for the fan. I'll have to see if I can find the post and read it again.

Hey Bill,
As of this moment, I can't remember on what specific document or, printout, or CAT spec that states the C-7 was the new generation "Zerkless" fan bearing. I have heard and read in the past where some C-7 owners were a bit skeptical of permanent fan bearing so, they ordered up the 3126 parts and, installed them on their C-7s and they now had zerks to lube.
But, there may in fact, be a few early model C-7s out there with zerks but, the general consensus is, no zerk fan bearings on them. In some ways, based on advancing technology, a permanently lubed bearing if reassuring. But, to the sort of, diehard maintenance dudes, not having one is bad juju. I'll take my chances, I figure they've must know what they're doing in redesigning a part like that to be permanently lubed.
