[Tigers] Centerforce Clutch Shudder

[Jay Laifman]

>From what I understand, it is generally caused by burning the clutch.  This
is either from heat/friction or oil dripping on the clutch.  I don't know
how that type of clutch is adjusted and matched.  But the WORST time and
greatest risk for burning a clutch is when it is not fully off or on.  In
the slippage area.  The longer you are in the slip zone, the higher the
risk of burning.  Just one good slipped burn out can toast a clutch like
that.

And it's all surfaces that need to be checked: flywheel, clutch plate and
clutch.

Happy for people to tell me that's not all there is.
