  • Ford 660 loader hydraulic hose connections
  • I am in the process of restoring the 660 after it was in a fire.The cosmetics are done and I have it running.All the loader hydro hoses were burnt off and I need to know where they connect from control to loader.Any help would be appreciated.

  • Your loader has two single acting lift cylinders and two double acting bucket cylinders. It is also equipped with a valve with two double acting spools which requires some thought on the plumbing. The side ports on the valve are the IN and OUT ports for the pump and reservoir but I can't tell which is which from the pictures. I would expect the body to be stamped with some sort of legend indicating which is which. There is no indication of a front pump on the loader frame so I am guessing it was using the tractor hydraulics under the seat for the loader? If so send me a picture of that area.

    Before I go any further have you checked the valve and cylinders to see if there was any fire damage to the seals? Its pretty clear they got very hot.

  • OK - looks like you are using some variant of the Selectrol valve to power the loader off the tractor hydraulics. Your connections are as follows

    1. Pressure OUT on the selectrol valve goes to IN on the loader control valve
    2. OUT on the loader valve goes to the return on the selectrol valve.
    3. Each spool on the loader valve has two work ports on the top side. For the bucket spool one port goes to the base connection on the cylinders and the other port goes to the rod end connection. You do the same for the other spool and the lift cylinders.
    4. Since you have two cylinders on the bucket and lift arms you need to use tees to connect the cylinders together. Run the line from the each workport to the right side cylinder and make the connection there with a tee. Then run another line from that tee to the cylinder on the left side of the loader. You may find it more convenient to put the tee in the middle of thoise runs to keep the length of hose needed to a minimum. In the interest of neatness I would suggest someplace other than the work porstr on the top of the valve as you currently have them. I would also suggest you ditch those plumbing elbows and replace them with steel high pressure hydraulic fittings like the pipe swivels you have in the elbows. You can use high pressure 90* swivel elbows which will keep the fitting count to a minimum and make the installation a lot neater and more professional.

  • Upon closer examination using zoom it looks like the lift cylinders are double rather than single acting. Still need to know IN and OUT ports on the valve as well as the source of hydraulic power.

  • Start by identifying the model of the loader and control valve.

  • For some reason after many trys I can't seem to get Photo Bucket to work to send you photos of what I have.
