<VV> Micrometers vs. Plastiguage

[Harry Yarnell]

You are correct. I believe the specs are TOTAL clearance; a.002 would be
.001 all around.

I use plastigage all times but, have a concern about both ways. If rotating
member is resting on bearing ( 0 clearance ), the plastigage measures the
total clearance, same as a micrometer... isn't it ?This means, at least to
me, that, if plastigage and/or micrometer give a total clearance of, say,
0.002", in fact when rotating there is a clearance (or oil film around) of
0.001"... isn't ?
Just trying to have this clear on my mind.

both sides.>>
