@Vetech63 I absolutely loathe parts guys right now. I have the parts manual for this machine. Found JLG has a seal kit for this dump cartridge (p/n 7010560). Local JLG dealer said price is cheaper if I order that seal kit direct off JLG's website. $31 after shipping and they have 1 in stock in Georgia. I received package, removed valve block from machine, opened UPS package and found this:

Package clearly states correct part number and and item description, but the only thing in the bag is a M'F'in sticker!!!!
LMAO!

I my experience when the CORRECT o'ring is blown there is often an under lying issue. It is common for hose flange ends to be cracked in high pressure applications (6000 psi) .

Update:

I have 2 hydraulic shops near me. A father owns one that only works on big hydraulic stuff, the son owns an equally sized shop that only works on small hydraulic stuff. Both shops are large, an employ lots of people. Big shop says my valve body is too small, go see the other shop, 5 miles away. I go see the owner himself of the little shop. He examines it and says basically my part is scrap and that there is a machine shop in Marne, MI that specializes in building one off replacement valve bodies and hydraulic manifolds, but it isn't cheap.

I talked to a close friend who's dad owns a modern machine shop. My buddy and his dad looked it over and sent me to a fabrication shop nearby to have it ground out and welded up. I got the welded part back yesterday and dropped it off to my buddy at their shop. They actually have the cartridge tooling for machining manifold and are going to try and salvage my part.

Not to throw shade as I wish you luck in repairing your block, but that crack extends all the way to the pressure port, not just what you see. Have you searched for a used block, do you have the part number of the block?

The machine shop that did the welding chased the crack with a mill until it stopped in an adjoining port. Is this a surefire fix? I don't know. We'll see if it turns out. The part was scrap before, and if it stays scrap, that's a bummer, but I'm no farther behind for trying it.

As for a used part, yes, I called many equipment dismantlers across the country and nobody has one. JLG's p/n is 4640716. A search on machinery trader shows 3 dealers with 4 parts in stock. A call to all 3 dealers showed nobody actually has that part anymore and Machinery Trader's advertised inventory is incorrect. That said, this part was installed on 9 different models over a 8 or so year period in the early 90s, so if you have a lead, by all means send it to me. I'm losing money by not having this machine running right now.

Haaaahhhhhhh!. I'd be peeved if that was me, but its not me- so its hilarious.

Sorry your having trouble getting it fixed. Call the rental house until you get yours up?

Edit: I saw you've been renting. The joys of old cheap equipment, means you can afford to have 2 pieces of old equipment, so you have either a parts machine, or one you run when the "good" one is down.....:D

I have to laugh about your last comment. I saw another JLG for sale fairly local, 40H instead of a 45HA. Slightly smaller machine, straight boom, but was priced under $5000. Machine was complete and operable, but had a bad leak from the boom. I considered it, talked to seller and discussed it with my wife and then decided I didn't need a project machine right now. Fast forward 6 weeks, that machine would have had the part I need today as they share the same accessory valve body. I could have swapped valve blocks and been right back to work.

Long over due update:

Lift is still broke down for the same part. Part was welded, machined, and installed back in July. I ran it for about 10 minutes in my yard and then had a geyser of fluid coming out. @partsandservice was spot on. It cracked right through the weld.

So, valve block went to a machine shop in August to have a new manifold block made. I went there this morning and retrieved my parts, still sitting in the bucket I dropped them off in. That shop is slammed with work and can't hire enough guys to keep up with the workload for their big contracts, let along side projects. So, I picked it up, and headed to a hydraulics specialty shop a ways away. They specialize in manifolds, custom cylinders, etc so this is their thing. They said they would have me a quote by next week, and if agreed, could have me a new block in 3-6 months.

At this point, I've been renting a lift as needed, climbing when it makes sense, or turning down some projects that didn't make financial sense. I'm looking to get this lift operational so I can trade it off on a 65ft bucket truck.

I see bucket trucks around here pretty cheap. I'm west of Peoria, IL about 25 miles. You purchase a running something, I'll go get it and have room to store; no problem.

I always used ductile iron manifolds usually made by Daman in Mishawaka IN. The expansion/contraction rates of steel vs aluminum due to heat /cold cycles will always create issues.

I just got off the phone with BMH Hydraulics. They quoted me about $1100 to make me a new manifold out of ductile iron with an estimated delivery in 6 weeks. I said get it done. So, if all goes well, I should have my lift operational by April.

BMH came through big for me and completed their end of the project mid March. I picked up the part, but it sat on my bench for about 3 weeks until a nice day came along to install it. New block is made of ductile iron, cracked block is on right. These guys even took the time to replace all o-rings, and clock the fittings. Install was plug and play, not fighting hoses, etc.

Lift is on its first job in 9 months because of thos block. Glad to have it back.

I dunno about becoming some parts king. I think most guys would have scrapped the machine or parted it out before they dropped coin for a new valve body on this old of a machine.

I paid $5000 for the lift. So far, I've replaced 3 of the controls for $480, a final drive for $900, this valve body for $1100, a thermostat for $10, and some PM work. Counting my labor, I've doubled the purchase price on this machine in repairs. Now, I've got a quote from a tire guy for $2000ish for 4 new tires (8.75x16.5, foam filled). The tires are in very rough shape, but keep going around for now. I'd like a wider tire (9.5x16.5 was a factory option), but they aren't any cheaper.

You may have dropped some coin in it, but at least you know what you have and what kind of shape it's in compared to purchasing either a new machine or another used one, that broad as it is long question, but again, at least you know what you now have. In my experience, age and hours on a machine mean less than the condition it's in. We have two old Gehl DL-10H telehandlers, one with over 10K hours, that I maintain and keep in service because the boss won't pull the trigger to replace them. And that's what sucks for me, I hate DL Gehl machines, didn't like them when they were new, from a mechanics point of view that is. But here I am keeping two of them going and the damn dinosaurs refuse to die! And therein is the rub, as much as I hate them, for me, as the employed wrench bender, like the line from the John Wayne movie The Train Robbers..."something to do".
