The jackshaft seems to only have an up/down tilt range of adjustment via the wiggle room around the 4 bolts that mount the pillow blocks. And 1 tensioning adjustment bolt above the rear pillow block. That range of adjustment won't help the angle that my pressure pump pulley is skewed. Maybe I need to bore out the 4 open slots on the pressure pump mounting plate to allow it more left/right wiggle room to align it with the jackshaft pulley

To heck with that, I don't want to touch my jackshaft, the blower belt is lined up perfectly!
This has to be an adjustment on the pressure pump. But there simply isn't any more range of movement within the slots that surround the 4 bolts on the mounting plate. I suppose I could just remove the pump and file the mounting plate slots to be a little larger on the side that counts that would do it, but why wouldn't the factory mounting plate (with an identical spec pressure pump to the oem pump, I'm certain of it) already have the proper range of movement?

Ok so now as long as you dontneed for the pulley to go closer to the pump , you should be able to pull the pulley out and lock it down with it's set screws wherever it needs to be on the pump shaft. Unless its at an odd ball angle( / ) then i don't know what to tell ya .a cds owner need to weigh in and give ya some advice
By this picture. If thats the pump pulley (big closestin pic) than it needs to be moved out. Does your new pump have the same footprint as the old??

Yea the pump has the same footprint. The pressure pump pulley would need to go in toward the pump not further out, but it is as close to the pump on its shaft as it will go, it hits a raised edge and thats it.. I adjusted the jackshaft backwards a bit, and then used a dremel to widen the slots on the pump mounting plate, got it lined up pretty good.
Then as I was watching it run I noticed the pump pulley has a wobble to it!
When I was first prying the old pulley off and the armature got jammed, it seems that it quirked the whole pulley. The dang thing looks wobbly when it is running now, not just the flanges but the whole thing. Which I imagine will probably fry the bearing or something else in my pressure pump if I don't address it soon. I was trying to find a simple vbelt pulley with no clutch to replace this wobbly one online today and so far it is difficult to find a 24mm bore 7in OD vbelt pulley that takes an A class belt.

The closest pulley in the pic is the jackshaft
Well if you need a good used clutch i got one. I don't think it has much time on it at all. Magnet looks new
