I welded on something to mount the diverter valve, still need to drill a hole. I know it’s not a perfect weld, but it‘ll hold.

GMC Detroit (destroyt) diesels are ridiculously common parts and what not everywhere for them. Anything hydraulic is all LEGO parts (i.e. any hydraulic shop can get parts). Axles can be troublesome if they are weird, but you can probably get parts for them even if they are weird and its likely got a Clark or Allison trans so those are common enough. Brakes and clutch stuff can be relined as needed as long as the metal bits are hosed. everything else can be NAPA sourced, or fabricobbled to make do.
I had the brake power clusters (an air cylinder bolted to a master cylinder) rebuilt, the other brake components were available new or rebuilt, brake shoes were good, wheel cylinders are available new https://www.ebay.com/itm/334057898957?epid=74389887&hash=item4dc76703cd:g:1LcAAOSwVZBeVltB. There are 2 different wheel cylinder part numbers, this is one of them. Each wheel has two cylinders. The Terex dealer had about half of the other stuff I asked for. Other places have stuff too, some do have ransom prices. Overall it hasn’t been too bad. As the other guy sad, a lot of this is common stuff.
Plus I recently got confirmation that the transmission can be rebuilt, a place in Dallas has everything to do it. Exchange price is almost nine thousand, he said about $5,500 if in running condition. Allison doesn’t have the parts anymore, but they do.
A lot of what I’ve done with the machine is here.

Thanks for the info but I missed the machine by a few days. Person that bought it was shipping it to South America according to the seller. Asking price was a grand and seller stated brake and steering work was needed but the machine was operable. Probably just as well, I have too many projects going already.
I’ve been rounding up the log forks/grapple parts. They were here, but scattered. I just found the cylinder mounting pins today. Only thing left is the bolts to hold them in, and I won’t know what size until I go up there. I’ll take all the bolts with me. I need to go through the cylinders also. I did one already, but don’t know if I got the backup ring in right. I need to check. The other I couldn’t get the pin out of the tube/barrel end of the cylinder, so I dismantled it and brought the internals down. I need to clean those up and install new seals, then wrap and load for the trip up. I have new hoses too, I’ll install all that up there. This has been put on hold while I swapped in a turbo engine with 42 hours. It’s running now, only a few things to take care of and I’ll be using it. Still need to wire the diverter valve and controller. Snow could shut me down at any time, but even if that happens I’ll be ready early next season.
Turns out these backup rings are flat on both sides, so I didn't have to take it apart again.
Did that last fall.
Well, this is about ready to use. We put the one cylinder back together up there, and installed the other one. Then we put on the hoses. Still need to grease the pins, and look at clamping the hoses in place. I remember there being clamps, I’ll look at pictures.
Finally had a chance to try out the diverter valve yesterday, it didn’t work. Now I need to troubleshoot that.
It rolled forward when I released the parking brake, too much to pin it. But you can still get an idea of what it looks like.

Pin on buckets/attachments can be a real PIA to get hooked up. Hope you figure out your diverted valve issue. The one I have on the Kubota is pretty straight forward. 2 lines in, 4 out. Push a button and my curl function works the aux port on the loader. Don't know what style you got though.
It’s probably just not getting power, a friend told me how to test it. It’s magnetic, he said remove the magnet part and have someone pull the trigger inside the cab. If it magnetizes, it’s working. We might go up tomorrow and check it out.
I didn’t have pins for it either, same friend is offering these. They’re close enough to make them work.
Yep same way mine is actuated. The connector on the coil on mine has a tattle tail light built into it. Whenever it's energized it has a little red led light that turns on. Handy feature.
We tried to magnetize the solenoid by pulling the trigger, nothing. Then we put the wire that’s supposed to bring power to the solenoid directly to the battery 24v, nothing. Then we also put the ground wire to the battery, it magnetized a little. My son said when he really squeezed the alligator clip lead to the ground wire, it magnetized stronger. We put the solenoid back together and tried it with the grapple hoses connected, it still moved the tilt cylinders. I used the really tiny gauge wires that came with the controller, now I’m thinking it needs thicker gauge to make the magnet work.
Do you know the amp rating of the coil? Normally they arnt super high.
No I don’t, I’ll look into it.
The pin length will reach through, the bushings aren’t worn enough to get the pins through. One or the other will have to be machined, I’m thinking of opening up the bushings.
