Recently purchased a Guilin (LW-6) backhoe attachment with a subframe. The "face seal" connectors at the end of the backhoe hoses did not match up to the metric threads on my tractors' quick connects. No one had metric size face seal adapters. Spent many hours on the net and called almost every hose fitting company out there, including Canada, to no avail. Took the hoses and quick connect to 3 different local hydraulic hose repair shops. They said they couldn't put hose ends on a metric hose (16mm), they said their ends wouldn't fit, it would be too dangerous, too much liability, etc. etc. Went to one last place. The owner, an old-timer with 41 years in the business, took me in the back. He put the hose in a vise-like setup, brought down an abrasive cut off wheel and cut the end off in a small cloud of rubber dust. He took a 5/8" crimp type hose connector X JIC and after grinding some rubber off the outside diameter of the hose he crimped on the new end. Did the same to the return hose. Two connectors (crimp end by JIC), two adapters (JIC by metric), one new quick connect, and after 20 minutes and $56.00 I was on my way home. First problem solved. He said he guarantees his work---if I have any trouble bring them back. Got home, set up the hoe, greased all joints, connected to the tractor and presto, my new backhoe came to life. MORAL OF THE STORY-you gotta find the right guy. Now to get the subframe brackets welded to the tractor and I should be good to go.

George,
You should post those pictures you sent me so you can show it off. The hoe location you picked is super good, mounted close to the tractor like that. Just get your sub frame connections welded in that position and you should be good to go.
BTW, the way the old timer treated you should be an example of how every business should view their customers. My hose guy won't work on used hoses at all.

Hey, I just use Aeroquip SAE re-useable fittings. No crimping involved.

I had the same problem with my YW-6 Hoe. My hydraulic shop crimped a fitting to my return hose but was affraid of the pressure hose. I didn't use the Jinma pump and it had bolt on flanges with o-ring seals.
I took a piece of 1/4" steel, drilled a hole in the center and two mounting bolt holes. I then welded a 1/2" pipe nipple to the fabricated flange. I filed the face of it smooth and bolted it to the Jinma pump flange, I had an adatpter that is metric on one side and 1/2" pipe on the other.
I'm using the YW-6 on my 3510 Branson and it works great. I'm using the tractor hydraulics with no problems.

I also like the Aeroquip reuseable fittings.
The process of reducing or removing the outer rubber covering on hydraulic hoses is called Skiving (with a long I). It use to be required by some fitting and hose manufacturers. It allowed the outer sheath of the crimp fitting to grip the steel braid instead of the rubber outer covering this was considered more secure. Having made lots of hydraulic hoses in the past I would not be afraid to skive a hose to get a reuseable fitting to work as long as it still fit quite tightly into the outer sleeve.
