Looking for 4 hoses for Case 580B backhoe. Part numbers are D55987, D55988 and 2 hoses D55989. No longer sold. Ideas?? Thanks!
 
Im guessing these are some kind of special ends that are
not available at hydraulic hose shops. At this point, you
would have new hoses made up with ordinary swivel
fittings. Then you would buy an adapter that fits the new
hose and braze it onto whatever special piece that was
discontinued. Or, the hose can be removed from the
special attachment and installed on the new hose using a
new thimble on the old attachment. The type of fitting
and/or length of hose will be dependent on how much
room you have. A picture of the hose would be helpful.
 

Looking at the 35 Backhoe attachment it looks like those could be the hoses from the hoe control valve, going into the boom, to the lines for the bucket and dipper cylinders. A shop that makes hoses should be able to match the old ones up if you take the old hoses to them. Depending on their stock level, they might have to order in some fittings.

The online parts book for the 35 on a 580B shows D50376 as a sub for D55989, D50377 as a sub for D55987, and D30378 as a sub for D55988. I don't know the availability of those.
