Anyone wouldn't have a picture of the inside of a good transmission would they?

A good transmission would be even better  <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt=":D" title="Very Happy" /><!-- s:D --> !

With the trans in nuetral, what should spin if I rolled it around or jacked it and turned a rear wheel? Right now the gear train that is in the picture that shows the grinder work is what moves. No movement in the shafts/gears forward of that. I would like to prove out the &quot;siezed gear&quot; theory. 

I hadn't thought about the worked over with a bench grinder part having once been a gear. I bet Chris is right, it siezed a gear, stripped another, neaderthal with a only a bench grinder, welder, pliers, hammer, screwdriver, and a metric adjustable took this apart and molested it.

Poor little 550 has been victimized.  <!-- s:cry: --><img src="{SMILIES_PATH}/icon_cry.gif" alt=":cry:" title="Crying or Very sad" /><!-- s:cry: -->
