new to me FP1 gear moving

Hi all,

Recently acquired this 1951 FP1. Had to ship it across the country since there are next to none of these available in Seattle. Still waiting on UPS to deliver me the tooling...which is ok (for now) since I can't fire it up yet anyway (no wiring for it). It's a 220v 50Hz Siemens motor, which I assume is 3 phase. The paint job is well worn but other than that seems to be in serviceable shape. It's just the right size for my shop!

I was testing out the functions prior to attempting to wire it when I noticed when I shifted the upper left most gear lever to the position closest to the table that the spindle would no longer turn from the handwheel. Pulled the cover and saw one of the driven gears seems to have wandered down its keyway over time and the dogs won't engage at all.



The drawings I have seen don't mention how this gear is retained along the keyway, but I do see what looks like a pin through it. Or a cover for a setscrew, I'm not sure. Anyone removed the gears on the driven shaft before? Here is the "pin" in question.




Thanks!
