Bushings in loader arms are too small, so couldn’t pin it. But did cycle the cylinders, I’m guessing more RPMs will make them work together.

Bushings and lower pins arrived today. It doesn’t look like I’ll get to it though, supposed to snow Wednesday and Thursday. I’ll pick up and move down before then.
Unless you run some sort of tie bar between them they will always open and close like that. Same reason there's a tie bar/plate on a quick attach, keeps everything timed together. Not really a major issue in this instance as it allows for an odd sized object to be grasped by both arms vs just one grasping at the highest point and the other not grabbing anything.
Finally!
But had to stop just as we needed to jostle the controls to get the pins the rest of the way in.

It's completely installed now. I disconnected the hydraulic lines before tilting it all the way down, to make sure I didn't rip them out. They just reach, I repointed the quick connects to give a little slack. Then I resealed the quick connect fittings on the loader side, they were leaking. If the pins don't look right, it's because they were given to me, they're sticking way out to put the lube hole where it needs to be. No action shots/videos yet because the starter seems to have quit on me. It has 25V from the batteries, but doesn't engage when crossing the solenoid. Or work from the key, obviously. Starter ordered, will fell trees in the meantime.
A couple problems with that starter 1. There was interference getting the hex head bolts in there. 2. Once one bolt was in, the other 2 wouldn’t start. The holes didn’t line up. The original starter is now at the rebuilder, and supposed to be ready this week. I started a return on the aftermarket starter, but seller hasn’t responded yet. I’ve felled 21 trees, so I’ll have lots of logs to move once the loader is running again.
Nothing a die grinder couldn't handle 
Nice project! I converted an old Kubota tractor to accept quick tach attachments. Best thing I ever did to that tractor.

Yep, it's small compared to your loader, but it does what I need and that's the whole point. Call it what you will but it's pointless to have something you can't or won't use.
Grinding 1/16 to 1/8 off each for bolt head clearance isn't going to hurt anything but rebuilding the original is the better option anyhow. Local parts house has always been able to source anything I need for starters and altenators. Rebuilding them isn't brain surgery.

Not such a problem with the cap screw in your picture. But I get the feeling you already know that.
They originally should have had 12 point reduced diameter bolts in the starter. Someone at some point changed them out. Those starters were pretty universal back then. For some reason the aftermarket hasn't quite figured that out.
Nope, the Terex green paint on the hex head bolts tells me they’re original. The replacement engine was later, and it had those.
interesting, I've never seen a Detroit that didn't have the 12 point starter bolts in it.
Have you seen any that early, 1977?
possibly,we didn't keep track of when equipment or engines were made. Didn't really make a difference in fixing, rebuilding or machining them. Everything was done off equipment and engine serial number. Model year didn't mean much, they were (are) basically Legos of engines, designs didn't change much over the years.
Defiantly haven't seen them all, but that's something I would have remembered.
Mine originally had the emergency air shut off. The later engine swapped in doesn’t need it, different design. That might help identify if you worked on engines that early.
yeah, thats an earlier one, rebuilt a coupple 4-53rc engines for tow behind leaf vacs that had the air flap on them. Pretty ingenious for the time period. Most we did were 6-71 and lots of 149 series out of 60-100 ton terex haul trucks. Didn't see many of the smaller engines, so I guess i should make a cart blanc statement like I did.
