Interestingly, I started looking around for a regulator (and gasket) to have on hand because they are cheap and they do go out. Going to the CAT site (parts.cat.com) and putting in my serial number (8YL) the parts list for the regulator pulled up the following:
115-4223: REGULATOR TP - 126-5466: GASKET
119-3075: REGULATOR - 126-5466: GASKET
Both have the same size specs but no operating temperature listed. So I call my local Cat dealership's parts department and give them my serial number and get a completely different part number:
284-5421 Regulator 222-5915 gasket
What gives?

Call Caterpillar Corp with your engine serial number and ask: 877 777-3126.

Will do Brett. Thought a CAT dealer would be using the same database as CAT.
