A friend called me was wanting to add double remotes to a early series D17 with a single remote can someone tell us what we need to do and if this is doable The tractor has a flywheel on the torque housing also. I haven’t been around a D series since I was a tiny fella in the early ‘70s |

If I understand, you want to use your D17 on a 2-way cylinder correct?
Im in the middle of this same project myself

I can send you a picture when I'm done. If the D17 has a transport valve you're almost there. The transport valve has a pressure and return line. Get yourself a 2-way hydraulic valce wiht about 2000PSI relief. Feed it from the standard remote. Put a T into the return line and plump that into the valve return. A D17 has a high pressure (3000PSI+) low volume system. So this setup will get you 2 way hydraulics, buy they will be much slower than a standard low pressure high volume tractor. |

your NEW hydraulic valve should be OPEN CENTER so that the pump can recirc back to the tank ( case ) when not feeding the cylinder UP or DOWN... Dave, i assume you put your FACTORY valve held OPEN position and feed constant flow to your NEW valve, and use it only ? something like this ?  ------------- Like them all, but love the "B"s. |

Thats how I have it Steve. The hydraulic lever on the quadrant would need to be up all the time to keep supplying oil to the new valve. My "New valve" is actually an original Allis valve off an old d17 wiht this option. My setup will be like original, but an aftermarket open center center valve would be the same.

Picture of my valve installed as promised. Original Allis valve and bracket. Thanks to Lonn for the valve and Orange Knight for the bracket, transport valve, and return line!

Not sure I would hose clamps for that much pressure.
OOPSY, that line is the return line. Me bad.

| Is the clamps I’m sure on the nonpressured return line |

I have the factory set up but there is still pressure on the booster gauge. I checked the lines for damage and checked the valve to insure it is open center. I would think there should be no pressure when the valve is centered. Is this normal to have pressure? It has a transport valve. ------------- http://lonsallischalmers.com |

There is a fair amount of work to do and at the end of the day the low volume system means your cylinders will move very slowly. You will also not have any hydraulics when you have your foot on the clutch. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

I just finished the plumbing this weekend. My disc is in the middle of what looks like a pond so I haven't actually tried it on a cylinder. I'll have to look at the Traction boost gauge when I start it next time. I put a gauge on both remotes and only got 900PSI. I wanted 1500 so I'll have to pull the valve apart some time, but it'll work for now. Mostly I wanted it to hook to our tandom rake hitch. Hydraulics just swing the hitch soo 900 should be fine for that. I has having trouble trying to figure out a return line. It was too close to make a hydraulic line and I didn't want to mess with trying to bend a 3/8 or 1/2 steel tube only 5" long. So i finally decided some fuel line with hose clamps might work easy enough. Replaced the worn seat bushings and spring to while I was working on it. I don't bottom out now on every bump! Sure rides nice.
