Bob and Thomas,
 
    I= vaguely remember hearing the description of the 20B eccentric shaft tool f= rom someone a long
while back (probably= from Mark Steitle) but have not put my mind (gett= ing feeble) around it............
 
  A photo and o= r a sketch of this device would sure help myself and = others of the group that may
have this job in the= ir future.................
 
Thanks,

Yeah .... was expecting that = but it;s good to have the exact specs (threads, etc.)=20
Kind of like the 'dent puller' they have in body shops.

Crazy pricing for a once use tools.

Thanks.

Thomas,
 
Be sure you have the = means to separate the two parts of the eccentric shaft before you crack the= case.  It is a simple tool that the dealer wanted $800 for.  I m= ade one from parts in my scrap box in about 15 minutes.  It consists o= f a threaded rod with nut, and one end threaded to fit the hole in the shaf= t.  18 mm, don=E2=80=99t remember the pitch, but it is the same as the= O2 sensor.  and a heavy chunk of metal with a loose fit hole that the= rod goes threw it and reaches beyond the end of the shaft.
 
Of course you may kno= w all this already.  Good luck!

A little prep work bef= ore I start my rebuild.........=20
Is there any machine work that needs to be done to the eccentric shaft= (such as would be done with a crankshaft?)
 
How do I know that I am replacing the rotor in the correct position.
 
I won't crack the case open until this fall but these are just the nag= ging questions I have.
