1966 FORD 3000 Gas throttle question

i bought a decent 3000 over the weekend, has some wear and tear but seems like a solid machine, except for needing rear tires pretty dang soon.
i am making a list of things that need attention before i stick it down in the woods on bush hog duty for the foreseeable future clearing my home site.
the throttle needs some work, i have the shop manual on the way since this machine is different than the two N series i have. i want to replace some of the throttle linkage rods, and most of the locking clips for the linkages are missing.
one thing i noticed right off the bat, the throttle has an arm that pivots on a center bolt that appears to attach to the intake manifold the bolts is loose, and the hole it fits into is wallowed out, causing the arm to cock sideways and is wearing a groove in the intake. i suspect that is wear some of my throttle issues are coming from, plus if its broke it needs fixing now.
the bolt has some sort of locking pin on the back side, but i cannot get a good look or feel it well enough to see what it is. hoping i don't have to pull the intake manifold, but i may have to to make the repair

can anyone recommend a fix, or give some ideas?

i was thinking i may be able to add some sort of bushing to the hole to repair the wallowed hole.

i took a look at the New Holland parts site, and it seems one of the springs i have is not original, its a very large heavy duty spring. could be the wear on my pivoting arm is coming from with such a high tension spring. i am guessing, maybe the friction discs are worn out, if i take that odd spring off, my throttle will not stay where i set it, goes back down to idle when i let go of the throttle lever i will snap some pictures after i get home this evening
 
Here are the pictures. The large spring is the one I am not sure about. And you can barely see the bolt behind the spring that is loose with the wallowed out hole.

(quoted from post at 15:16:39 06/15/20) In 3rd pic that tin piece with rib come off and behind it is a nut with compression spring. Titen it cork disc may be gone/wore out. That spring is too big.
So a spring should be there? Going from the parts diagram on the new Holland website it does not show a spring.

It has a huge amount of tension. I had a very hard time getting it back on when I took it off. Dang near a trampoline spring!!!

Ill take a closer look tomorrow and look for the friction disc.
 
Yes, there should be a spring in that location, but it is a much lighter spring. That one looks like the spring from a bunk bed me and my brother had when I was a kid. The support underthe mattress was a rectangular grid of heavy metal wires that was supported around the perimeter by dozens of springs, similar to a trampoline.

According to the parts drawing, the correct part number for the spring in that location is C5NEB464B if you don't have the optional foot feed throttle pedal, and C5NN2472C if you do. partspring.com claims they are both in stock, so you should be able to get them from any New Holland dealer, but they are fairly pricey. The first one is listed at $57.00 a piece, and partspring only sells the second one as a "Package of 2 (cannot be sold in single pieces)" for $252.00. Messicks will usually sell individuals of the things that partspring only sells in multi-packs, but usually for a couple bucks more than the partspring's individual prices based on the multi-pack price.
 
for that price, i think i will find a comparable spring local. i am not about to pay 50 bucks for a spring. it better be a space shuttle spring for that kind of dough. i think the friction disc is gone, and they used a bigger spring to compensate so the throttle would stay i one spot
 
FWIW: here are some pix of our 65; the spring seems pretty stout though Ive never removed it. Carb is a Zenith replacement for original Holley.

no worries, i just put my computer on its side and the pics looked just fine.
the spring does seem to be about the same as mine in size and thickness.
 
finding parts for the old N series is MUCH easier than this 3000. to buy the friction washer for the throttle i would have to buy a pack of five. so i found a dealer way up in New York that had them in stock, bought one from them. found the misc clips on Ebay for the throttle rods, bought parts, operators and shop manuals for the tractor. and i just realized i did not notice the bell crank yesterday, so i may need to order one of those as well.
once the manuals come in, i should be able to sort out the throttle issues, looks like i will have to pull either the starter or maybe even the intake to get the pivot bolt out for the throttle pivoting arm. i may just make due for now. i need to work this tractor for a month or two clearing my home site and surrounding acreage. once she's done her job i will work on getting her mechanically right, and then work on getting a fresh coat of paint.
