OK, you are right around the time Caterpillar changed from grease zirk on the fan hub to sealed bearings. If greaseable, you need to VERIFY that it has been greased (access from the bedroom).
To see which you have, call Caterpillar Corp with your engine serial number: 877 777-3126.
Also, ask if their records show a valve adjustment. If done by a Caterpillar dealer, the corp should have a record of that.
If not, you are due for your first valve adjustment. ONLY from someone who works on the 3126 for a living-- NO OJT!
