I went to local hydraulic shop today and got the one made, cost 40 bucks. But the gal said I had reuseable fittings on my hoses. I never knew they had suck a thing. All the hoses on my dozer have ends like this. A big nut screws on to hose outer via left had threads, and then the inner one screws on the inside with right hand threads. The gal said I needed a "mandrel" to use these fittings on bulk hose. Does anyone know what this "mandrel" tool that the gal was referring to?
When I got home I tried to unscrew the fittings, and the first (inner one) cam out with no problem, but the outer nut really wedges itself on the hose and if the hose is deteriorated like mine was, then it twists apart right at the back of the nut and leaves a splintery piece of wire/rubber left in the nut. I was able to drill out the center a little bigger which grabbed the wire and helped untwist it from the nut. So I am thinking the "mandrel" is to aid in removing the fittings from old hoses? Any thoughts?
