l553 aux hydraulics

[downrigger]

HTH. I'm sorry about not saying what steer skid i was asking about for aux hydraulics it a new holland l553 thank you for the come back.

I would start with the dealer. They may have a kit for your machine. I know on mine, I looked at trying to pull together something myself (I used to design hydraulic systems) and there was really no clean way of doing it that I would feel confident in. So, I made friends with the parts guy at the local dealer and he looked up all of the parts that I would need (BC had discontinued the kit for my machine). Again, hope this helps.

SkidRoe has you on the right track. There is only one main component that you need for any aux hydraulic installation and that is the power beyond fitting. Everything else can be sourced locally. I think it was item 14 in the diagram SkidRoe referred to. This may not be the valve you want however, The way the hydraulic lines are run in the diagram this appears to be a single acting valve, in other words pressure will be available on only one coupler.

I have that hydraulic set up on my L553 and I only have the 2 lines with quick disconects on them. When I turn the valve on my boom and bucket cylinders won't work. What else is needed to add the lines to the boom. Is that tee in the line above the valve some speical fitting or do I just have to add 2 lines to get power beyond to the lines on the boom? I sorry if I hijacked this thread but if he hooks his up this way he will end up like mine. I have a snowblower that I would like to try on it.

Hi Ivan,
I would have to agree with Mike, I looked at that setup, and it does look to be single acting only, which you have now confirmed.
Basically, it you can get power beyond functionality out of your existing loader control, you would need to replace the aux valve (basically a divertor valve) with a 3-position, 4-way control valve - commonly known as a wood splitter valve.
Referring to the link for the aux. kit on the Messick's site (above) to plumb this control, hose # 12 would be your supply, hose # 18 would be your return, and tubes #22 & # 23 would connect to your control A & B work ports. You would not use the tee, item # 19.
Strange that NH would configure it this way. The only attachement I could see using with this is a backhoe, or some other attachment that you would only use when stationary, equipped with it's own control.
For general interest sake, my BC uses a 3 spool control. Too easy. I don't know if this is an option or not, as could require a lot of re-plumbing.
HTH.

The aux valve shown is not for boom hydraulics where the couplers are out at the end of the boom. In the linked page you need to go up a few lines until you see boom hydraulics. The basic plumbing is the same. You install the power beyond fitting into the present control valve power beyond port. This will supply pressurized oil to what ever control valve you install. You will then need to run a return hose from the return port of the new valve back to the loader control valve and tee it into the return line to the tank. Then it is just a matter of running your two work hoses to wherever you want your couplers located.

Ivan it sounds like you tee'd into the line from the hydraulic pump to the loader control valve for your oil supply to the new valve. In a properly plumbed valve the bucket has priority, then the boom and then finally your aux valve. That is because the bucket spool is the first one in the valve to receive oil from the hydraulic pump. If a power beyond fitting was not used it will also cause some strange things to happen since you are pressurizing the loader control valve in the return circuit.

thank you for all the infor.i'm thinking i might have it done.it sound like some thing that i could mess up real easy.thank to each and every one who got in on this.jim

Does anyone have a picture of the pressure beyond fitting that is used for the L553 skid steer?
