Hydraulic hose on front end loader problem

I have a four 3400 tractor with a front and loader. The hydraulic hose for the lift cylinder on the left side came off yesterday. I tried to reattach it but was an able to get it to screwback on. There doesn't seem to be any screw threads on the female screw. This is my first experience with the hydraulic hose. The hose appears in good condition I just can't get it reconnected??
 
Your post is really hard to understand, I went to modern view and it didn't get any better! Are you using a phone with auto-
correct and not proofreading? Anyhow, it sounds like maybe a swivel fitting pulled apart, otherwise there would be threads
showing. First of all you need to find out why it pulled apart, correct that, and then replace the hose. I think you need some
qualified help!
 
We don't know your experience/ skill level. So, I will start very very basic.

Be careful. Is the loader down on the ground, or blocked up? If it is raised at all, doing something with the hose could cause oil to shoot out and
the loader to come crashing down. Be careful!

Most loaders have a quick connect these days. You can move an outer sleeve on the connection and stick in or pull apart the hoses. Would this
have come apart? They can be very difficult to push back together if there is pressure on either side of the hose. Probably only a tiny bit of oil
would drip out if a quick connector came apart.

Did as someone mentioned a swivel break apart? Likely a bunch of oil would come out and leak and dribble if a hose broke like this. It would
leave the hydraulics open on one side, oil in the system would be free to come out.

A picture of the two ends that are apart would be worth 1000 words to us?

Again, if you are not experienced with hydraulics, be careful, we don't want anything to drop on you or shoot high-pressure oil under your skin.

Just like a bolt and a nut, hydraulic hoses and cylinders need matching threads in order to attach to each other.

The two most likely possibilities here are:

1. The threads are stripped out.
2. The threaded end has broken off the hose, and is still attached to the cylinder.

In either case, you need a new hose. Remove the old hose and take it to a farm equipment dealer or a hydraulic shop. They will make you a new hose to match the old one, with the correct ends on it.

It will be expensive, but if you want to own and operate old tractors, that is the price of admission. They are old. Things break. Repairs and replacement parts are expensive. Just as sure as the sun rises in the morning, death and taxes.
 
I was attempting to use photos from my phone but was unable to
get them to upload straight from the phone. I hope the pictures
upload from the computer.

Your 90 degree connector simply broke off. Remove the piece from cylinder with a easy-out. Take the entire hose off and have a new 90 degree end put on it. Or a straight end and a 90 degree elbow fitting, if it was too short.
 
It is just broke off. You will need an extractor to remove broken piece from the cylinder and a new hose or hose end. Find someone nearby who understands mechanics and get them to help.

Went out to tractor and was able to get both the hose and the
fitting off. Heading to town to get replacements.

Thank you all so much for your help,
 
To get the stub out of the cyl fitting- insert a punch, or bolt, etc., to fill the space inside of the fitting, then use a pipe wrench on the stub. If you put a wrench directly on the stub you will crush it.
