'64 C-60 with pto driven hydro pump and twin two stage lift cylinders
I blew a hydro line for the dump bed and opted to redo all the lines together given their age. In the process of removing the lines from the lift cylinders, I noticed some crud in the sump of the cylinders so I went ahead and dropped those as well to drain and clean them out. At that point, I took every last fitting and joint off the hydro system except for the reservoir and under-mounted pump itself, figuring I may as well replace everything since im in this deep.
During standard operation, the bed never stays in the raised position, and slowly drops back down whenever raised, but there are no external leaks in the system anywhere. I figured while everything is apart I might as well attend to this problem. Question is though, is it likely to be the cylinders causing this, or the pump? Additionally, assuming I just go ahead and have the cylinders rebuilt (they likely need it), is it worth rebuilding the pump as well?
Curious on your guys input. I haven't gotten a quote yet on the lift cylinders, but I cant imagine that twin stage cylinders are going to be cheap to rebuild.
