I used to have a great Hydraulic guy who in 2007, when I tightened my bypass up too tight and popped hosed like candy, found a thread not exact but close enough that it worked to the Jinma (224) loader and even though the hose was too big for the ferrule, he would strip most of the rubber down to the wire and these are working to this day. He retired and even though i have one of the units I can’t get anyone to put them on a used hose. The ferrule of this fitting he used successfully has W03310-06 embossed on it but as its on the ferrule that probably does me little good as it could be used with multiple fittings. I really just need to find out the odd fitting that is on my loader. It may be different from most, I know the cylinders are definitely different from nearly anyone with a JL20 so its possible that the fittings are different also. I think the loader is a previous model year as when i assembled it did not work and the Chinese air freighted, yes, you read that right, air-freighted me a different part than the delivered on, that holds the loader to the tractor. Anyhow, if anyone know the thread , or has a part # I would appreciate it. Previous Hyd guy just called them some Chinese metric crap, don’t think googling that will help.

Once again the book is slammed shut. From the OP’s response, or lack thereof, one can only assume the OP is disgusted with the results from his inquiry.
Well, the OP is a bar near me, doubt they are disgusted or wish to respond to anything on this site. If the OP is me, then I guess my response to you was not read. I assumed that when I responded by email to you, which is how I saw your post, it would be posted on ctoa. Seems that is not the case but I would think that you should have received my email.

I did not receive an email from you. What email address did you send it to?

I don’t know what being trolled is, doesn’t sound good. I don’t spend my days on the computer. I responded to an email I received from CTOA assuming because I received the posts, my reply would be posted, if not anyhow you would receive it. If you don’t, I can’t change that, I assume only you can, being it’s your wordpress site? Below is what I replied to you, which you did not receive.

Pete,
I’m not sure what size/style your tractor has because Jinma seems to like to change things up without warning.
My 2006 284 front end loader uses European DIN fittings in some places and metric o-ring face fittings in other places.
The dealer I bought the tractor from doesn’t have a clue about hydraulic hoses and fittings so I had to go searching on my own. Caterpillar dealers can get some of the DIN fittings and custom make hoses with different ends. When I worked there, they had nothing in the metric o-ring fittings. However, you can find some adapters to go to JIC fittings. This is expensive, but at least you can get hoses with JIC ends made just about anywhere.
Here is a hydraulic fitting guide from http://www.discounthydraulics.com
If you can post pictures of your fittings and maybe measure them using this guide maybe we can figure out what you have and what you need.

If the cylinders fittings are welded in they will need to be dissembled to be cut out and new one’s welded in I would think (heat and hydro seals do not mix) . But if you have access to a machine shop adapters should be able to be made to convert what ever to what ever. But I have not had a lot of luck finding people with skills and or time to do small things like that around here.

I agree with David.
Strip down your cylinders and take them to a welding shop along with the fittings you want to use, but then you will still have to buy two new JIC hoses per cylinder PLUS one adapter for each hose. Or just buy the metric ORFS to JIC adapters for around $30 each (two per new JIC hose). It would be an expensive process to reinvent the wheel and change over all the fittings to JIC. Your best bet is to accept what you have and use the appropriate fittings. ORFS fittings are used world wide and very popular on heavy equipment.
