And then there was a 310...

[Toolslinger]

I prefer the separate ground as well. The lights are aftermarket up on the cab, so they're set up with 2 wires already. Running a ground line around will be simple enough when it dries out.

There are a lot of loose, or missing bolts holding the cab on/together. That's not the ground path, but it speaks to condition I guess. That's going to be a whole other thing, getting the cab to stop rattling... All the parts breakouts tend to show items in isolation, rather than part of an assembly. Only a couple of them have ghost images of their surroundings so you know how things relate. They're very nice drawings as is, but a little context would help in many cases.

I watched a video of someone working on a 410 last night. Deere went with a pretty complicated hydraulic system compared to what Case did. High, Intermediate, Low, and Tank pressure zones in the system, variable displacement pump that is demand controlled. I've got the full tech manual, so I am beginning to understand it. Supposedly, it is a very smooth running system that will handle multiple demands at once without dropping flow anywhere with no issue, but it became complex as a result.

And now I've got the "Getting to know you" song running loops in my head... Thanks... I did that musical just a few too many times over the years I was in the arts...

Sorry about that. Although I suppose there are worse ear worm songs you could have stuck in there!

Managed to get a few more things sorted out...

New seat bottom arrived. Much nicer than the chewed up remains that it came with...
I'd like to replace the back unit too, but it isn't completely gone yet. I do need to make some support brackets that are missing, but they're the same on the JD300, so I have something to work from.

The parts came in to finish up the wiring for the heater's blower.

Also managed to get the regular 6" fan running for ventilation. Don't know how long that one will hold out, but I'll keep working some oil back in the bearings...

Got the new wiper, and arm installed. I need to change the angle a little, but it's ok for the moment.

While I was up there, I pulled the front work light apart. There's a reason they're dim... 17 watt, 28 volt bulbs. Obviously they have to go... I had one 20 something watt 12v on the shelf. Far brighter, but that's never going to be of any use. I expect I'll just end up replacing all the fixtures with LED units. I can get some hot LED's to put in what I have, but they cost as much as a complete fixture, and I have to replace the crushed one anyhow... That will come together when I do some of the re-wiring. I'll be putting some big LED's in place that will draw more than the existing, and the current wire isn't going to be up to it. Probably have to make a relay bank with diodes to make the 3 lighting options work. I also found where the wire is supposed to be for the loader tower mounted lights. They're all MIA. I ordered a few 100' rolls of different color wire as this is turning in to a complete rework... Of course, I'm doing all this because I can't do much else with missing hydraulic lines... The odds of me using the lights is pretty slim. I've used the lights on the other tractors only a handful of times my entire life.

Pulled the floor panel over the battery. Going to need to do something there... Battery is just sitting on a shelf, loose. The parts machine is a bit older, and has more of a box setup. Strangely, sitting on the shelf in the barn is the kit with the hold down hooks for the earlier setup. I thought perhaps they were from the JD300 we've had for years, but I don't think so, and that's the only Deere we've had... Strange.

Monday, I got a hold of the guy that was making my replacement hoses again. I hit him up after 3 weeks, and he hadn't done them, but swore he'd take care of it that week. Monday was a week, and a weekend after that. Still no hoses. That was it. As much as I want to support a local shop, that's some bullshit. My neighbor picked up my old lines from him since he was heading that way.

I brought the hoses with me to work this week in NJ. Ran over to a hose shop, and handed them over the counter. Guy asked if I was going to wait, and I told him I'd run out for coffee and be back. He told me not to bother, he'd be done before I got back. 15 minutes later I had my 12 new lines. What a complete waste of 4 weeks waiting for the other guy to do anything. Lines are never cheap, and these were no exception, but lesson learned... Don't bother with the hobby shops, just go where they know their business. Picked up coffee on the return to work. The guy was right, the coffee shop was 10 minutes away from his shop.

My upcoming weekend is kinda ruined already by a wedding taking up most of Saturday... Hopefully I can at least get the lines on if I hit it hard Saturday morning.

Toolslinger I’ve found the same in my area. There one shop that will make them while you wait but they are expensive. Harry

And I'm back at the 310 today... Just in time for it to be 34 degrees outside.

Apart from the cold, it was pretty nice out. Clear skies, and no wind to speak of.

There aren't many photos. Apart from not wanting to touch my phone while covered in hydraulic oil, I was busy questioning the lineage of the JD engineer that designed things here... At the spools, I had to disconnect, and reconnect 10 fittings.

I would like to see the wrenches used during the OEM assembly. The mess of tools I ended up using was ridiculous. You have to think several moves ahead to put the hoses on in the right order, or you will not be able to get a wrench in at all.
The cab gator was packed with tools. Had the generator with me to throw a charger on the battery, but strangely, the battery was fine.

Second gator was making runs back to the barn for more tools, or the odd bolt for hose clamps.


So, 12 hoses... 7 hours. The two long ones out on the boom only took 10 minutes.

Those hoses are going to make me nervous forever. No other way to do it though with the extendahoe option. Like to replace that mangled steel line, but I've only seen one, and it was sold for just shy of $300...

End result is... It works. And, weirdly, I didn't see any leaks. Something will leak, as it always does, but so far, everything is good.

[JSinMO]

Looks like a fun time! Glad you got them all done. Fingers crossed you can ruin it for awhile with no leaks.
I don’t know what to say about that steel line, really going to have to keep an eye on it.

[Toolslinger]

Yea, it bothers me... I need to call the local breaker yard, and see if they have one.
I'm not actually worried about it failing as the bend is actually pretty smooth. No kinks, so it's just bent badly. That's not to say I'd try bending it back.
I'm really more concerned about catching it on something while telescoping out in brush. Doesn't help that it has to pull that long line through the guides all the time as well. (which is another poor idea... I should probably get some armor for them.)
I wouldn't say it was Deere's finest moment of engineering. Even when it's in the correct shape, it's kinda exposed. On the other hand, I'm sure they weren't thinking of operating in heavy brush with a unit they figured would be ripping up streets, or digging on more open lots.

[Toolslinger]

Huh... And just like that, a NOS unit hit my Ebay search...
Should have it in hand in a week or two.
That factory paint is going to look out of place on this tired old warrior...

On a lark, I checked to see if I could get the plastic spacer that is associated with it, and to my absolute amazement it too was available. I would suspect that failed at some point due to age, and the use of a hydraulic breaker on the machine. It was never replaced, and with that line loose, either a branch got under it, or the hose got caught on something and pulled it back. Ordered one of those as well. The associated hose clamp that supports it all is not an issue, I've got those (just not painted a pretty yellow).

Next up is figuring out the backhoe bucket mess. The 12" that is mounted is not a JD unit. I really wouldn't care, except it wobbles around on the pins enough that it might become an issue. Also, when they put the mounting ears on (it was a QD unit) they got some geometry wrong, and the bucket can't curl in as far as it should. I'm not loading dump trucks, so that doesn't matter, but that also means the teeth can hit the boom bottom, and that isn't right. It's in good shape otherwise, so I imagine I will add some bushings to fix the wobble, and keep it for small trenching.

The 24" bucket is beat pretty bad. I expect that was on the machine for the majority of it's life when not running a breaker. The two outer shanks are worn down to nubs, and will not hold a tooth. I had the same on the 646 buckets, but my welding can hold up to that machine. I don't think I could get a tooth to stay on either of these via weld. So, either I have to do shanks, and likely the cutting edge, as well as possibly some patching on the sheet metal, or I have to pick up another 24". My feeling is the 24" is what I'd want to have on for most applications, and since I have to have the specs on hand before I order the Amulet HoeClamp, making those decisions is going to be high on the list as I'd really like to get that thumb on there to deal with another project in the near term rather than years down the road.

The 36" bucket also has badly worn shanks, and cutting edge. I might just cut the shanks off, and put a straight edge on there. If I ever use a 36", it would be to do some dredging in the ponds. I don't need teeth for that operation, and probably would be better off without to keep a smooth bottom. The machine really isn't heavy enough to be digging with a 36 unless it was silt, sand, or loose gravel. I have silt in the ponds, but everything else here is rock, and high clay content. Smaller buckets will work, just take a little longer. 36 is at the bottom of the list, and will likely just get set in the woodline for a future year.

Finally will need to get some more hydraulic lines for the loader. I should have pulled them with the last batch, but I was thinking of a quick turnaround then. They're a little harder to get to, and in a horribly filthy area under the machine. I had hoped to powerwash it, and then get after them, but the delay in hoses means the water lines out to the fields have been drained, and winterized. I don't want to wash this thing right in front of the house, so I either have to haul a tank of water out to a field on a nice day, or wait on that until spring comes around in lateish April when I turn on the water.

Backhoe control valves were never nice, regardless of using pilot control or old school mechanical linkages to move the spools.
One thing to consider (if you don't already have a set) is a crow's foot line wrench set...

If you are lucky the hose and fittings are smaller than the nut on the end, and you can wiggle the crow's foot down the hose, and then use a long extension and ratchet to spin the nut. Choice words are usually spoken regardless - especially if you have to remove hoses starting at one end so you can get to the leak in the middle.
