Subject:      2.1l main bearing - the whole story

2.1l main bearing set:
Just bugged a couple of VW dealers some more, and
finally found out the whole story.
It goes like this:
There were 3 different STANDARD main bearing sets originally
installed by the VW factory when the engine was built.
(These are NOT oversized bearings for machining the case or crankshaft.)
025198461A  That's the most common bearing installed.
025198461A004 (red dot)  It's  1/4000 next larger standard size (smaller
than blue).
025198461A001 (blue dot) It's 1/1000 larger (largest standard size).
You don't know what bearings you have or combination of bearings until
you split the case and look for red or blue dots or no dots on your
crankshaft.
The first standard size is the smallest. So if you see any dots, blue or
red,
you need to get the corresponding larger size bearings. (See Bentley).

In addition to these 3 standard bearings, the VW dealer sells
oversized bearings (.25 mm and .5 mm) for those engines
that need to be machined.
