#35 Loader Hydraulics

I sent you a picture. Hope it comes thru.

You got it. As I recall the connection at the bottom of the dash between those two lines is made with a double male brass fitting with pipe threads. Take the line off that goes to the touch o matic (tom) and throw it up on the shelf. Screw a 45 degree pipe elbow onto the open end of the pressure line and plum your feed line to the loader into this pipe fitting. The 45 makes for a better lay around the shifter hump. This should feed the in for the spools. Take the plug out of the tom on the right side and put it in the left side. Now route the return line into the hole where you took the plug out. This saves you plumming and makes a neater hook up.

Each valve has to have two hoses coming out of it to go to the cylinders. One is for up and one is for down. I don't know how they came from the factory but I like to push down on mine to make the loader go down. Those two lines can be swapped depending on which way you like to move the lever to make things go up or down. Just make sure you use one pair (two from one valve) to go to the same cylinder hook up.

Got your pricture, it was a big help. The loader is mounted and working great. It is a little tight on the left side adjacent to the orchard muffler, but beyond that it went on without much difficulty. Thanks for the help.

I am only guessing but you should be able to get one of those loader manuals from JD for a nominal fee. They are a little scrawny book but have all the diagrams in it on how to lash it up with the 420/430 - for both trip bucket and hyd bucket.

I am assuming that your loader may have the antique valves on it. If it does, my book shows two return lines because the bypass in the valve/valves did not have an internal passage to return by passed oil to the touch o matic.

If they haved been replaced with modern spools it should only have one return line.

As I recall, that plug you are referring to on the right side is just the other end of the galley that was bored thru the housing and goes into the same place as the one on the left that the pressure line is going into. So with an open center and routing your supply oil as stated earlier - it would go from the connection at the bottom of the dash to the lift and then the supply that has to flow out of the open center valve/valves on the loader goes into the now plugged side on the right and the port where the pressure line goes into now on the left gets the plug put into it. Now after the oil flows thru the loader stuff it goes back into the supply/pressure galley on the tom (touch o matic)for use there. That oil is actually flowing all the time around and around and as it goes into the tom it goes thru bypass valve/valves until there is a demand put on the tom by the operator changing the position of the control levers for the three point.

Dang, I rambled and also I have my loader and tom off the tractor in restoration and will be putting it back together with a remote valve - so no pictures.

If you want, I could later scan a couple of shots out of the manual and try emailing them to you.
