Subject:      Rod journal size for a 2.0l?

 Hi all:

 I've been slowly, slowly working on the rebuild of two 2-liter
 Vanagon engines.  I recently got a set of outside micrometers and,
 never having used micrometers before, I thought I'd practice by
 measuring the diameter of a connecting rod journal on one of the
 cranks on my bench.  I got a measurement (more or less) of 1.968
 inches.  So, I looked up the "correct" measurement in my various
 manuals and here's what I found:

 Clymer's "VW Vanagon 1980-1982 Shop Manual":
      2.1644-2.1653 inches (54.95-55.00mm)
 Haynes' "VW Air-Cooled Vanagon 1980-1983 Owners Workshop Manual"
      54.95 to 55.00mm
 Tom Wilson's "How to Rebuild Your Volkswagen Air-Cooled Engine"
      2.1648-2.1654 inches (54.98-55.00mm)  (1700/1800 engines)
      1.9677-1.9687 inches (49.97-49.98mm)  (2000 engines)
 Bentley's "Official Factory Repair Manual"
      Not listed

 So here's my questions:

 1)  Who's got it right in the above list, and why the hell would an
 "Official Factory Repair Manual" (Bentley) not list such a vital
 dimension?  (Or, maybe it does, and I just can't find it?)

 2) If "majority rules" and the proper dimension is around 2.165
 inches, does it make any sense that I'm measuring a much smaller
 diameter?  Ignoring "operator error", (I'll go back tomorrow and re-
 measure this), is it possible that Tom Wilson's book has the
 dimensions backward, and I have a 1700/1800 crank in my 2000 engine?
 This engine was rebuilt by VW of Canada, has a "CV" code, and the rod
 bearings are marked "STD".

 Thanks for any help.
