Something you really might want to consider doing. The two hoses that feed the boom cylinder and the ones you replaced, you might want to remove one end and slide some nylon over them. That will do two things. Protect the hoses from ultra violet light which destroys the outer cover but most importantly, the sleeve will defuse the stream of oil in case of a failure causing the oil to spill to the ground and not to your face. I lost a finger to oil injection. You get shot in the face and the oil enters the eyes under force, you lose you life.
I have an older JD 310B backhoe that is exact as your backhoe. Do you know how to add an auxiliary line for a Thumb? Btw, I used to have my hoses made at NAPA and one day I went to Tractor Supply and their prices are a lot cheaper for already made hoses and they got different sized to choose from. Thanks
Excellent video mate! I have had extensive experience with hydraulics on similar gear. I agree with washing everything down as best you can before starting, definitely don't want dirt etc getting into the system. If I have to run pipes through tight spots I tie a rag on the end so no crap gets in there. If I have the time, I use a high pressure pipe sealant on the connector threads too - it's ok if both connectors are brand new but if you work with one new and one old or otherwise, leaks and drips can develop over time. The sealant will either give you no leaks for the life of the hose or at least a longer time to failure (failure being a leak, weep, etc). Hydraulic oil is also very flammable! On things like tractors, grass and dust from work duties settles on leaking or spilt oil and makes it a whole lot easier for a spark to ignite the oil - i've had enough stuff catch on fire while welding or grinding I do a check of everything now and either get it off with compressed air etc. and shield it from sparks. Another tip for others, when you have a hydraulic hose go for whatever reason, when you replace it with a new one, the system runs at a little bit higher pressure as there is no longer a leak, and the hose is a little more rigid being newer, and other weaknesses in the system have more pressure put on them thus more leaks or failures! It was definitely the right decision to replace all of them. Be prepared for other hoses to go, or rams to develop leaks, soon after you replace one or change the system in any way.
You never put ANYTHING on those threads. The fitting seals on the 30 degree flare and if you contaminate the flare on the sealing surface you'll have a leak. The only time you use thread tape or dope is if it's a npt into a female npt port. You are correct about the transfer of pressure to the old hoses because of less expanding of the new hose or hoses. The system is only as strong as it's weakest component.
I have same backhoe and one of the hoses on bottom (the same one you had problem getting loose) just busted? I can not get to it with my wrenches, how did you get to bottom hoses so easy? Any help would be appreciated!
The Amazon Hose company in Tampa made these hoses hand did a great job. The hoses were @ $30 each. You can also buy custom made hoses from Discount Hydraulic Supply. You pay wholesale for the hose and fittings, $10 assembly fee plus delivery. Check 'em out.
Any chance you can send me pics and locations of the short hoses from controls to the metal block? Had a guy come out and started working on replacing them, didn’t mark where they went and he never came back. So kinda screwed me
Flare wrenches will NOT work on this. The hose is too large to get a flare wrench (they are for Metal Tubing) on AND those large wrenches are Extremely Expensive. On Backhoes, it would be a good idea to chain the boom to the dipper to keep them from sliding and wasting more hydraulic oil, there are NO back flow preventers in the system. Putting Swivel fittings on Both ends in the tight fitting places is a great help. If you have power to your work, using a Hot Air tool to heat up the stuck fitting can help, do not use a torch or a fire is likely and it will ruin any o rings.
in a case like this i like simpal masking tape and a sharpie pull 1 hose at a time and lable 1st outlet on tractor 2nd the inlet on the hoe with same # then when reinstalling just put hoses from #1 to#1 wo a diagram hehps when you hahe diferent length hoses or should i call it a list hose#1 22in. #2 24in. ect.......
Good video. Thanks for posting this. A hydraulic hose on my Farmtrac backhoe burst today and this will help me replace the broken hose.
One of the greatest uses for a cell phone!!! Love being able to take a before picture!!
how do you stop the hydraulic oil from coming out of the hoses?

Nice job, I'm thinking by the looks of them you would have had to replace them all in the near future anyways good call on doing them all at once.

thank you for this helpful video i have on old Leyland tractor that has a broken hydraulic hose on the loader.
I usually mark them all with numbers.
beautiful! i'm not used to digging into a repair project without a chain effect occurring... perfect scenario.
how do you replace the hoses inside the wall cylinder of the backhoe????
I have same backhoe and one of the hoses on bottom (the same one you had problem getting loose) just busted? I can not get to it with my wrenches, how did you get to bottom hoses so easy? Any help would be appreciated!
Your probably going to have to remove some of the other hoses to get to that one.
typically florida, the bird sounds and the foliage. fl boy right here
What was your source for the new hoses?
