Mark from the fort 09-27-2009 20:56:11 74.97.225.100 75938 Report to Moderator	I am thinking about "tinkering" with a loader on my TO35 and use the tractors hydraulics. I couldn't find it in the older posts, BUT, I remember reading about being careful when putting the fittings on the tractor. Could someone tell me the correct thread size of the "test ports" on the TO35s. Last thing I want to do is cross thread and screw something up. If I stick with a trip buckets, can I just run one pressure line from tractor and the split that into two lines to run both lift cylinders? Will gravity return fluid back into tractor via same supply lines? or will I need a return line to a different location on tranny? Thanks to all, Mark [Reply]   [No Email]

A single line is run from a pressure port on either side of the front of the transmission cover, with a tee to feed both of the lift cylinders. The allen head plugs are standard pipe thread - forget whether they are 1/4 or 3/8". The system pressure could be 2700 psi, so it's safest to use hydraulic fittings rather than the very much cheaper iron pipe fittings. They have a working pressure of 300 psi or so, and could rupture. The single line will feed oil back into the transmission when the control lever is lowered, just the same as the three-point lift ram in the internal system. Cheap and dirty, and works! The next step would be a switch valve feeding a control valve to operate double-acting cyls or two separate functions such as lift and bucket tip. There are two- and three-spool valves that fit onto the top of the transmission to do this, but very expensive. It's cheaper to mount a switch valve on the transmission and feed an appropriate valve bank - ours is up on the loader right side, a bit below shoulder height.   [Reply]   [No Email]

You place the Position Control Lever on FAST and use the Draft control to lift and lower....   [Reply]   [Send Email]

This explains exactly how to do anything with the hydraulic system in a much simpler way than the tractor instruction Book, which is a bit of a novel when you try to read it. I will email it out to you...John   [Reply]   [Send Email]

You can plumb from the one pressure outlet- you can charge a 4 way valve control. So you can have all the pressures in all directions on your loader- but you have to run another line into the case, 'cause no, that pressure out to the valve is constant, so a return from the valve to the tranny will have to be sorted out. You will also need patience, this will not be anywhere as snappy as a pump off the front pulley or pto. As far as the threads? I don't know about fergies, but the allis was plain plumbing pipe threads- not bolt 'sae' or whatever. so yeah, do some finger tight milk runs first- good luck- tony   [Reply]   [Send Email]
