Hello! I bought a double set of hydraulic remotes for my 240 diesel and couldn't get them to put out enough to raise the disk bine but my 3 point has been working good. I currently have my main hydraulic pump out and the tractor split and would like to go back with an auxiliary hydraulic pump. According to my MF-42 I&T Shop manual I would want the dual section auxiliary pump and the drive train to tie the two pumps together . Is there any advice on what I need to make this work?
My serial is v32123 and it also says 2773 on the tag.

I don't know about a 240 but I have a 245 with auxiliary pump that supplies two sets of remotes. The hydraulic lines for the remotes run through the left side cover. If your 240 will accept an aux pump you likely need the side cover and correct valving and lines to go with the pump and drive train. It doesn't hook up like the add-on remote kits that use the lift pump. It maybe in an accessory catalog somewhere, however not all the 240 parts catalogs on the AGCO site show having the aux hydraulics available.

Thanks to both of y'all for taking time to reply. I'll be honest I'm very green with hydraulics.Am I understanding it right that the hydraulic pump by itself doesn't put out enough to run 3 point and remotes at the same time? I was hoping to have both. I guess I thought the auxiliary pump would be dedicated to the standpipe specifically for your remotes and the main pump would run your 3 point all at the same time but I realize I may be quite confused.

Hello Nate welcome to YT! I am no expert on the hydraulic system for that tractor but it seems like a few things were over looked before you came to this point. Hopefully you did not split the tractor only for the purpose of installing this auxiliary pump that you imply will be the ..fix.. to your problem. So a few things that need considered. Was the actual output pressure the remotes you added tested with a gauge? What is the pressure that the discbine requires? I am looking at a manual for a 230 which I would guess is fairly close to a 240 and it shows the 3 point pump to be capable of 25-2600 psi and there are adjustments to set it in that range. My understanding is that you tap into the 3 point hydraulics to add hydraulic remotes. I would almost believe that a discbine would raise fine with 2500 psi. Now with the tractor all torn apart we are looking around for the smoking gun but we have nowhere to put the powder cartridge! If in fact 2500psi is not enough to operating that discbine cylinder it may be possible to change to a larger cylinder diameter on the machine to get the tractor to lift it. If you cannot get the required PSI spec for mower you could check it with another tractor capable of operating the lift. Then you would just tee a gauge into the lift side hose and see what it reads.

I don't think you want a dual section pump, because that would have a section dedicated for multipower which obviously you don't have. You will also need the internal plumbing to send pump output oil to (and through) the left side cover. The cover itself is questionable. You may be able to customize what you have for the fittings. Maybe look for a used package of cover, lines, and fittings? That would probably come with lever provisions for independent PTO, which is also something you don't have.
