Loader Install on a YM3110D question

[PBee-HT]

Picked up a good used loader that was on a 2610D and plan to install it on my YM3110D. I have question on the hydraulic line hookups. The loader's control valve has three lines that need to be hooked up to support the hydraulics. I understand the small pressure line from the pump to the PTO must be cut and compression fittings installed for the hydraulic supply to the control valve and the third is a return to tank from the control valve. On the 3310D with power steering, There is a larger pressure line from the pump to a hydraulic block and then from the block a 3/8 line that feeds the PTO. Should the larger line from the pump and before the block be cut and used for the loader or the smaller 3/8 pressure line from the block to the PTO? The loader was pulled from a 2610 that a continuous steel 3/8 line from the pump to the PTO and did not have the hydraulic block in the line. Not sure if the loader supply should be installed before or after the block.

Just going to state how my 2002D with power steering is plumbed. Can't confirm yours would the the same. High pressure goes to diverter block and one line out of diverter block to power steering and the other out of diverter block going to the 3 point control valve. I am pretty confident this particular diverter block is one that makes sure the power steering gets enough flow before allowing the flow to go anywhere else.

The line has been cut coming out of the diverter block and going to the 3 point control valve. I have plumbed my loader in at that point and added a tank return line. Hope this makes some sense.

<E></E> Thanks, I was thinking the same thing. Is your line from the pump to the diverter twice the size as the line from the diverter to the PTO? I have a little confusion on the return to tank. All I have read, do not show this from the control valve, was not sure if it should be caped. I do have a fitting from the 2610 the replaces the dip stick on the Transmission fill to allow the return to tank hose to be connected there. I will assume it is needed. If I can attach some pic's you will see the steel line from the pump to diverter is at least twice the size. The diverter has an "out" feeding the PTO, "Tank" assume is going some where back to the tank and an "STG" Looks like steering and shuttle shift.

The in line to my diverter is larger than the other lines. Not sure it is twice as big. None of my lines are as large as yours. The extra 11hp makes for that. I have an opening on the side of my transmission I was able to use for the tank return. Shown in picture.

I am not understanding "Do not show this from the control valve, was not sure if it should be caped."

I would think the line on the diverter block labeled tank is a relief valve opening on the block.

I was trying to say, from all my reading and all the diagrams I have seen online, there has not been a return to tank shown for the loader control valve. You are the 1st that I have found that has one. I was not sure if it should be capped at the control valve or run to the tank. After talking with you, I am running it to the tank. Thanks, you have been a lot of help. I will cut the small line from the diverter to the PTO, add compression fittings to feed the pressure to the loader and run the loader control valve return (not cap it) to the tank. Thanks, again.

I think we are on the same page. Three lines from loader control valve. 1. Inlet to control valve coming from your cut line from diverter block. 2. Power beyond outlet from control valve going to other end of cut tubing line. 3. Tank outlet from control valve going to transmission sump.
