<VV> 1966 turbo

[FrankCB at aol.com]

Seth,
    Define "spin freely".  <GGGGGG>   It's never going to spin as freely as 
the fan that blows air around your  kitches/den/bedroom, due to the drag from 
the carbon seal.  But it  SHOULD rotate with one finger moving it, but with 
some resistance.
    Since both the turbine and the compressor wheels  are attached to the 
SAME shaft, they should spin with the same amount  of drag.  If they don't it's 
possible that the nut that holds the  compressor wheel on has become loose.

Can some  one explain how the  turbo should spin when removed. I took mine 
off 
and got  the  propellers on the exhaust side to move  but does not spin like  
it  does on the carb   side.
_______________________________________________

Define  "removed" - If the exhaust housing is still installed onto  the main  
bearing carrier with the stock V-clamp, and tightened up, the wheels   should 
spin freely. The tightening of the clamp onto the housing  compresses an  
area 
under the wheel, which allows the turbo to spin.  When the exhaust housing  
is 
removed, the seal expands underneath,  adding a bunch of drag to the spinning 
 
assembly. - Seth
