ComancheStarFarms Posted May 30 Posted May 30 I’m having some difficulty in trying to determine which male coupling to use? Not sure if this 1066 has the original style remote couplings or some modification. Additionally I’ve never noticed a bolt & washer on the backside of the coupling but I’ve never had much difficulty in connecting equipment either so haven’t paid any attention before. Two photos attached to help explain what I haven’t put clearly into words. Quote
Chester5732 Posted May 30 Posted May 30 It has been changed to the pioneer 8700. My 1566 has the same setup but I can not get the hoses to connect with those rubber covers on there. Quote
acem Posted May 30 Posted May 30 ISO conversion. They can be a pain to get hooked up and unhooked. Lots of brute force and awkwardness... Quote
HydroTek Posted May 30 Posted May 30 Put the tractor valves in float before you connect will make it easier and any pressure on the male tips will make it more difficult -- lock the machine in transport before disconnecting -- or be sure the pressure is off the hoses before disconnecting -- levers in float will help in both cases 1 Quote
Matt Kirsch Posted May 30 Posted May 30 It surprises me how many people don't know about the float function and/or don't use it, then struggle with their hydraulic couplings... After the chewing-out I got for not floating the disc before unhooking it, I never forgot to float before unhooking ANYTHING again, ever. 1 Quote
Drysleeves Posted May 30 Posted May 30 Those ISO kits were originally offered by IH in 1983 when the 50/30 Series started arriving with those couplers from the factory. I still have a copy or two of the IH instruction pamphlet that was in the non-IH box containing the kit. Quote
Chester5732 Posted May 31 Posted May 31 Mine plug and unplug real easy with the rubber cap removed. I figured the opening just isn’t big enough that it causes a problem. Quote

Some tractors have the float blocked off with the bolt under the lever. Mine all were when I got them. Quote
HydroTek Posted May 31 Posted May 31 Then , shut the engine off and work the levers back and forth until the pressure is off Quote
ComancheStarFarms Posted June 1 Author Posted June 1 Evidently I mislead the participants on this thread - - I wasn’t complaining about the couplings being hard or even easy to connect. I was just asking about the bolt & washer setup on the rear of the coupler. Replies point to them being ISO. That brand is new to me. I’ve seen factory couplings from tractor manufacturers & Pioneer brand - - but never a brand by ISO. So now I’ll ask, which brand is preferred - IH, Pioneer or ISO? Quote
snoshoe Posted June 1 Posted June 1 ISO international standards organization. Not a brand but a standard specification. Most pioneer are ISO and the names are often used interchangeably. 3 Quote
Drysleeves Posted June 2 Posted June 2 Bolt and washer is how the coupler is retrofitted to the existing casting. Washer is stepped to fit the housing and the bolt is threaded into the coupler to retain it for use. Rubber grommet keeps most of the dirt out and is retained by a small snap ring appliance. You can either cut a small "v" in the bottom of the grommet to allow oil to drip or drill a hole in the center of the bottom coupler slot and attach a fitting with a drain hose. First couple sets I installed years ago were not in IH packaging but had the IH instruction pamphlet and an IH molded in the rubber seal to occupy the slot where the old lever once lived. Quote
stronger800 Posted June 2 Posted June 2 Yes I got two sets (20years ago ish) at the dealer and that’s how they are. Quote
ComancheStarFarms Posted June 2 Author Posted June 2 That helps a lot DrySleeves. I take it that ISO couplers are the “way to go?” Quote
acem Posted June 3 Posted June 3 They have their pluses and minuses. They accept the iso/pioneer tips that are now pretty much universal. It's much easier to install the conversion than rebuild the originals. But they don't last as long for me as the originals. I like to run one of each on my tractors. Makes it easier to keep track of the hoses. 1 Quote
806Jordy Posted June 4 Posted June 4 I just converted my 806 to the ISO couplings, the reason being that I had just recently bought a 2450 loader that was set up with the ISO tips. I helped the guy that I bought the loader from take it off his Hydro 70, I was impressed at how easy it was to connect and disconnect the hoses. So rather than change the male tips I bought the conversion kit from RedRunRight. It took a little time and a home made bracket from angle Iron to attach them so they didn't interfere with 3pt hitch but Im very happy with the setup now. 1 Quote
HydroTek Posted June 4 Posted June 4 The ring on those couplers are supposed to be inside the aluminum housing -- that allows them to be break away style some are even push pull style 1 Quote
806Jordy Posted June 4 Posted June 4 You know I wondered about that, they work the way they are but I will change them tomorrow. I had planned on taking that bracket off and welding on a cap and painting anyway. Thanks Hydro. Quote
stronger800 Posted June 4 Posted June 4 Must take two hands to work them now though, one hand pushing in from the back. They’ll be much handier, once corrected Quote
stronger800 Posted June 4 Posted June 4 I like the top hose marker zipties. I do about everything like that 2 Quote
