75 5000 pto and pump questions

curious about a couple things.
reviewing the manuals, I see the pto brake can be adjusted externally.
Above the left floorboard, I see the slotted stud with locknut.
But, there are 2, right next to each other, both slotted studs with locknuts.
Which is the brake adjustment? and what is the other one?
looking at the part diagrams, I just can't make it out.
I see in one diagram, it says one is the locating bolt, but both slotted studs.
(just curious and learning, pto and pto brake work fine)

Next question,
main hydraulic pump is tired.
(PO didn't have the remotes set up right and the loaders gravity down was thru the relief valve, I fixed that)
I'll get around to swapping the pump someday, but until then,
can you physically reach the inlet screen and filter surface
from the left inspection plate?
I'm going to clean/flush the chamber and would like to physically scrape the probably there muck off the screen.
(pump is always noisy, not a relief noise, more like a straining to get its fluid noise)
Thanks
bad pic of the 2 adjustment screws, I can get a better one if y'all need it

Do not turn those screws. The pto brake can only be adjusted
after being removed from the tractor. Those 2 screws you were
referring to locate the hub that supports the pto cluch hub. You
have to remove the pump to get to the suction strainer. As long
as the tractor does not have load monitor you can remove the
lift cover to remove the pto clutch.
 
Those are the locator screws that set the position of the slip ring arm... don't move them unless you want trouble.
Pull the lift cover if you want to adjust the PTO.

Gary is correct, those 2 screws are not for adjusting the PTO brake, however they are ADJUSTABLE, and the proper adjustment is critical for proper long term PTO operation.
