Looks good.. how did you end up doing it?
Looks really good. I've been gradually replacing all the same hoses on mine. Wish I'd taken more time to replace the grease lines that are in there, too, because now one has broken off. I used split 1.25" Pex tubing for pads at the clamps where the 2 piece steel ones were missing.
i stretched the boom n dipper all way out onto the ground pulled off the three on one side off first .. the fittinges on valve side broke nicely but i had the put the torch to the other ends to crack the hold . you may have to undo the 2 pipe tube clamps inside the boom pull out one tube to the side reclamp the other tube back in the clamp to get room to fit and hold the tube in place so it don't twist and put 2 claw sockets on both fittings i tried useing one wrench but it just turns the entire hose and or pipe . one to hold one to break the nut . then i did three on other side . all hoses are different so if you get one mixed up you quickly find out hard thing is that the sleeve clamps on the hose in left pic are just a bit off on the hose so you got to manhandle them in and tighten them down in the holder with only two hands . the worst is the bottom four hoses go from 2 up side by side to four across then into a horizontal clamp at the base of boom a real pain you can just bareley see it in the right pic .. and also seems the hoses on the right sick out more than the left ? and i slide the tubes up some more on that side to and still . so i tested them out pulling a stump and the they got scuff ed up allready . that coil stuff pretty neat too 30$ 25 foot amazon but they'll get caked up with dirt fast.. got some welts on forearms when the nuts broke free . maybe lost gallon oil total . just cycle the stuff to get air out slowly at first also trying to tighten down the fitting with the elbows a pain . to keep the elbow orientated properly without turning as you tighten next im gonna try to do a gland rebuild for first time . only thing the after i pulled the hoses off the valve control for the bucket it wouldnt stop dripping oil out the connections o rings bad ? or the pressure reliefs or it it normal for a steady thin stream to come out ?? upper n lower
I can't say for certain about that control valve, but that's typically the result of anti-cavitation valves in the control valve sections, which would make it a normal thingy to leak. If you plan on owning/servicing that machine for years to come, best be to invest in the proper JIC plugs and caps for those fittings, that way you stop oil loss and prevent ingress of dirt. BTW, nice work.
