what hydrualic fittings do I buy?

Hi everyone, I'm new to the hydraulic lines and fittings world, my last tractor was an 8N so bear with me. I see lots of different choices on Amazon and they are too expensive to make a mistake. I need to be able to quick/disconnect this loader so can anyone give me the specific type or spec fitting needed to change these connections. The hoses are half inch standard hoses. With the tractor shut down and the loader on the ground do I need to do anything else before loosening the connections.

For generic coupling use a Pioneer coupler. Some tractors have their own proprietory couplers, so you"d have to use that brand. What tractor are you hooking up to? Pioneer would be the cheapest. To release the pressure after shutting down, work the hyd levers back and forth a time or two.
 
The actual hose into the swivel is almost always pipe fitting, it would appear that is so.

The swivel screwing into the cast body could be o ring or pipe fitting. I sometimes have a lot of trouble identifying those properly.

For quick disconnects as mentioned, use the Pioneer 'universal' pairs. They have become the standard. Other brands make that type, but pioneer is a good brand..... Note that quick disconnects do slightly reduce the flow of oil in a line, should not be a problem here but a consideration any time you add them.

So you likely will be getting new hoses, perhaps 2 hoses 1/2 as long as what your originals are, and replace the current hoses with a pair of hoses and a Pineer disconnect in the middle?

I think all hoses and quick connects would be pipe fitting.

If you replace the el swivel parts, thrn more investigation would be needed.
 
I'll agree,I have them on the bucket cylinder hoses on mine,BUT,if there's much movement in the hoses when you raise and lower it,it tends to wear out the O-rings in them when they turn on the male end and they'll start to leak.
 
It would be a good idea to mark each coupler & connection so you always hook them up the same way so the lever action will be the same each time you use the loader.
 
Simple Pioneer couplers are all you need. You will also need a short/close 1/2" pipe thread hydraulic nipple for each.

Thanks Bob, it's beginning to make sense. What type of nipples do I buy and are there special precautions with hydraulics like there is with air fittings and galvanized fittings that can flake?

Paul, I don't understand the reason for adding hose?

What do you guys use on the threads for sealant? The tractor is a Case 1490 with a 66 loader on it.

The 1/2" NPT 90 degree swivel fittings attached to the work ports on your valve will not accept high pressure NPT short or close nipples. The hoses presently attached have a reverse bevel at the end of the fitting that seals against the elbow. I have not seen nipples machined for that use. You may remove the swivel fittings and install 1/2" NPT high pressure street ells, then use the short nipples and ISO (Pioneer) couplers. The loader valve work ports appear to be 1;/2" NPT, if they are not, adjust your needs accordingly. Use only fittings rated for hydraulic systems of 2500PSI or greater. No galvanized or black pipe fittings.
 
Because they can be either pipe threads or o-ring, it can be a little confusing, but the parts should be available locally. Disconnect one of the hoses and take the el with you to a local hydraulic shop, tractor dealer, NAPA or even Tractor Supply. Show them the photos you have here and explain what you want to do. They should be able to provide the correct fittings, and you will be sure you are getting what you need.
It may be a little crowded around the hydraulic manifold, so you may want to add some short hoses so that the quick couplers are not all crowded around the valve.
 
You should have posted this on the Case DB forum!! Lots of guessing going on here from people who don't know anything about the loader you have. The two spool valve on your 66L loader remains with the loader when detached from the tractor. The two spool was powered two different ways. (1) from a remote circuit with quick couplers at rear and lever lock back. (2) a power beyond block on top of the remote valves. There will be hoses with a male and a female ISO coupling coming from PB ports on this set up. When these couplings are removed from the two spool They HAVE to be coupled back together to complete the circuit, or you will dead head the hyd. pump. Post some pics of the two hoses on the sides of the two spool and where they couple to the tractor down on the Case forum. We will help you there.

I went back and studied your pic, It appears that your supply and return hoses for the two spool are routed outside the rear fender and MAY be connected to the remotes. at the rear of the tractor. If so just uncouple them from the remotes and back out of the loader frame. Do you have the jack stands to support the loader??? All you have to do is remove the two big pins at the rear bottom of loader frame, uncouple the two supply and return hoses, and back away from it.
that loader couples and uncouples slicker then jelly ozzes from a filled donut.

No thread sealer. Just buy a Pioneer coupler with both the male and female end in the package.
 
Where do the jack stands come into play? It seems if I set the loader on stands and then back away I would topple them as I am backing away. Or do I set the loader on the ground and then support it with jack stands?

If I deadhead the pump as you say does that stop my hydraulics at the pto and lift arms or just at the remotes?

Listen to this guy. You may not need anything. Valve stays with loader when dismounted!
 
If indeed your 2 spool is powered by a power beyond manifold and you don't shut the tractor off to uncouple the valve you will deadhead and destroy the hyd. pump Expensive screw up. As I said, from viewing your pics. I believe your loader is powered from a remote circuit, but you have supplied no pic of the rear of the tractor, so I can't be sure,
See detail from my op manual for 66L loader. If you have the stands which pin under the boom during operation and are pined properly for detaching, the loader will set on the bucket and stands just fine on solid ground.
My e-mail is open on the icon to lower RH corner. Contact me via e-mail and I will send you this op manual.

These are the only two rear views I have on file as I'm currently away from home. I'm slowly learning and you have been indispensable in making things clearer, I can't thank you enough for taking the time Adirondack case dude! I however want to thank everyone who has contributed to this thread as every single post has somehow moved me closer to understanding and I'm taking it all in. I am unfamiliar with some of the terminology used but it is starting to come together. I was able to confidently order fittings with help from all of you. I'm beginning to understand the hydraulics as the IT manual arrived today and I read the hydraulics chapter first. Finally know what a friggin spool valve is and know my hydraulic pump is external and mounted near the front of the tractor. I plan on tracing all the lines this weekend. I have a very steep property and all of you have contributed to helping me remove this loader before I take this tractor up the hills and put the hurt on myself. Sometimes you may post and think it doesn't make a difference but I am grateful for everyone here who has taken the time to move me along the learning curve. I have followed up and made notes of your suggestions which have already saved me time, money and frustration. Can't THANK YOU all enough!

From the pics I have determined that you have a Power Beyond manifold. The fittings protrude up from it on the RH side of the seat. It looks like the ISO couplings are on the hoses rite by the bottom of the fender. That is where you will uncouple the two hoses going to the 2 spool valve, and be sure to RECOUPLE the two coming from the PB valve so you don't blow the pump wide open. I can't emphasize this point enough. You should not need any new parts or couplings if this PB kit was installed properly.
Loren
 
Yep , he was 100% right, You just disconnect the two lines coming into the spool valve and then reconnect theses line into one another. I have not disconnected the loader yet as all that remains is the mechanical part of supporting them but Adirondack guy has nailed it!
