Lots of teeth missing on the ring gear and the new starter motor's not faring too well anyway. The motor has to come out. Here it is all jacked up, ready to lift the engine. A bit later on, the engine's out. Might as well do a bit of housekeeping in there while it's out. There's a few other things that can be done, too, while you can get at things, like putting the guages in the dash where they belong.
