HWH hydraulic lines

[Gregory OConnor]

Many Hydraulic lines have one end fixed and one end with a spin fitting
(like the female end of a garden hose). You may want to mark the
orientation of the old line and maintain it with the repair as the
inner ply may come apart if the 20 year old line gets twisted out of
memory shape.

The line holds ram psi when the jacks are down and the bus is perched
atop. The hose is working while the pus is perched

when mounting a close attachment point, your design should realize the
up and down position of the ram fitting if it changes at all. It may be
that some length of free hose is requires to accommodate a change from
up and down.
I wonder how much of the failure is caused by lack of support and how
much is caused by degraded hose. I believe degraded hose is a cause
that your repair will not completely address. You may find that the
airquip type of no crimp may fail next if the hose is brittle. I gave
up using onsite repair of lines because the second failure is complete
and messy (however predictable).
