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. --------------------------------------------------------------------- Tom Young young@sherlock.SIMS.Berkeley.EDU Lafayette, CA 94549 '81 Vanagon --------------------------------------------------------------------- |
