Broken Hydraulic Remote Manifold Help

Was discing with our Landini Vision 105 and snapped the hitch pin on the discs. They stayed and the tractor kept going. Stretched the hydraulic hoses to their limit, they didn't release and the top half that set of remotes on the manifold unit (there are 4 sets of remotes) broke free. Here are pictures of it. In the picture it is the pair on the far right. I can't find a parts breakdown for it.

There are 4 allen-headed bolts which hold the 2 halfs of the unit together, they snapped. If you engage the hydraulic lever for that pair or remotes, fluid shoots out but if not engaged, it does not. The other pairs of remotes work fine.

Can I still use this unit? Or do I need a new top half for the one? Or do I need an entire new unit? What do you even call it? Manifold? Multiplier? Each set of remotes has a line running out of it and there is a line running in/out of the whole thing.

If repair is an option:
Obviously, I replace the bolts that held the unit together. The bottom halfs of the bolts have just enough metal sticking up that I think I can get vice grips on them. If not - drill them out? Extractor? Any recommendations?

It looks like an O-ring or rubber gasket of time kind goes in that recessed circle on the bottom of the unit? Am I correct? If so - any o-ring that fits or something special? The middle part of the housing appeared to break a little - I assume fluid does not pass that area, so it probably is no big deal? Thanks in advance for any advice.

First, I expect everything is metric, threads and O-rings. You have nothing to lose by trying to fix it and reuse it. Plug the holes in the valve to keep crud out of the valve while you are working on it. Be sure the adapter block is clean before re-installing it.

I would try to remove the broken screws by using a fine point center punch and tapping them counterclockwise to turn them out. I would try this before drilling. Socket head cap screws can be hard, if you try drilling use a left hand bit, if you can get them. It looks like a locator pin broke as well replace that as well. The O-rings (metric) should fit the OD of the hole with out force and be just slightly proud of the surface. Too big can prevent proper sealing. I don't think the broken area in the center will affect it.

Thanks.
I appreciate the info.
“Locator pin”- little pin sticking out between the sets of
mounting holes? Would any pin that fits work? I assume It is
mostly for alignment?

Don't see why that won't seal back up with new o-rings and bolts. But those couplers are not set up to release when pulled as far as I can see. They would need to be relocated and attached with the outer ring and have hoses go to that block

I didn’t know if they were set up for a quick release...I know now that they aren’t. Lol. Hasn’t been anything I have tested before. Thanks for the vote on confidence in repair.

The one coupler that is top row second from left looks like it would be the correct style for that setup. Should be able to push the hose in and pull it out without touching the outside sleeve. The others are meant to be mounted by the sleeve to allow them to break away.

Be best to get new o rings from a hydraulic shop, they are usually a harder material in an application like that.

Yes, it's an alignment pin, a dowel pin.

It will be too hard to hand drill the broken piece in the blind hole.

Just have to try to line everything up when you tighten the bolts.

But just in case it will come out, (try blowing beside it with air pressure), if it's metric you'll probably have to order it from McMaster.
