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

Crazy pricing for a once use tools.

Thanks.

A little prep work before 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?)
=A0
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= nagging questions I have.
