This Week's 356/912 Porsche Problem:



     OK, guys. You think you're so smart. Try diagnosing the following
itty bitty problem that cropped up today on the Maestro's Telephone.
     First one  with the right Experimental Approach gets a free
Spec Book. First one  with the right ANSWER also gets a Spec Book.
      A Customer calls (408) 727-1864. The Maestro answers. The Customer
has a 1960 356B Super Engine that came, already rebuilt, in the car he bought.
      The Customer had removed the Flywheel to surface and balance it
as part of doing a clutch job The Right Way, the First Time.
      The Customer, before sticking the flywheel back on, checked the 
End Play like a good mechanic should.
      Lo, a good thing too, for the  end play is Not Right. With a .035" shim
in place the  End Play is over 12 thou (0.012"). Since the End Play spec 
for a 356/912 is .004-.007", (and the Maestro likes .0055"), the Customer
figured he needed about a 0.042" shim which he ordered from Stoddard.
      The .042" shim arrived. The Customer installed it and  torqued the
flywheel to measure the End Play.  As the flywheel nut got tight,
so did the end play! As the  flywheel nut got really tight, the 
engine SEIZED!
     How can this be, asks the Customer. A .035" shim has .012"
End Play, so a .042" shim should provide .012-.007= .005" End Play.
But the  engine seizes instead! 
      The Customer  wracked his brain trying to figure out this puzzle
wrapped around  an enigma, but to Know A Vail. So he did the only
thing he could Under the Circumstances- and called the Maestro to
ask:  How come, Maestro?

      So, guys. How come? And how could you tell how come, given that
the guy has the two aforementioned end play shims, and two soft iron gaskets?

KEEP THE 356/912 FAITH!
The Maestro
