I removed the unit as best as I could (given that I've never done any work like this before) and I'm trying to figure out:

A) if the unit can be salvaged/what might be the problem. I don't see any obvious cracks, just some gaps and some rubber/putty? in a few spots.

B) if I should try to find another servo at a salvage yard.

C) ?


Also, obviously, there's a rust issue somewhere and the unit could use some cleaning. Should I remove the lower unit and clean it out? Any help would greatly appreciated. I'm new to this stuff.
