Here is a picture of the injector pump attach bolts, see the screwdriver flat?
While getting ready to install the thermostat, I noticed an extra hole in the gasket. Sure enough there was a hole in the housing that was blocked with corrosion. I took a drill bit and cleaned it out. In years past we used to punch a small hole in the thermostat for an air vent. This tractor comes with a built in air vent. What this hole does is allow air/coolant past the thermostat so it will fill completly without warming up the engine until the thermostat opens.

The slotted threaded stud that you have seems to be different than what I have, or in my case the slot might have completely been filled with gunk. Next time I'm there will check it with a pick. Your stud seems to protrude more as it seems longer. My impression was that the injector mount is somewhat like an alternator as you loosen the pivot bolt to adjust and tightening bolt to keep all in place.
