Huh????? You aren't insinuating that a workspace consisting of a pulverized into dirt gravel parking lot with a stiff 15mph breeze crossing over a heavily traveled state highway isn't "sterile" in cleanliness are you????? Not having immediate access to "CapPlugs", I went the trouble to stuff a cotton shop towel in the spaces vacated by the solenoid assemblies while I used non clorinated circuit board cleaner to degrease the "bobbins", followed by an isopropyl bath to remove any residue. LOL. Most everything on this machine is a dirty, greasy, and gritty SOB from lack on any kind of maintenance as it's cheaper to dump oil in it than repair the leaks, ( I suppose). There are two hydraulic hoses from the top of the proportial valves leaking at their respective crimp(s) retaining their ends and the oil stream is right down the face and behind the solenoid valve retaining plates saturating the solenoid coils which are open at their front. This will require hose replacement(s) which I have but need to order additional ends for quantity required. Here again is a photo of the solenoid coils in the boom lift section:
These have now been properly repaired and operate well. I did not seal them and do not know if they originally were?
With exception of the auxiliary hydraulic pump, flashing beacon lamp, and back up horn, all functions appear to be operational. I have a plethora of jumper wires installed to complete circuit runs for broken, or compromised wire runs, and several wraps of friction tape to insulate formerly bare copper strands where the insulation has deteriorated, and broken/fallen away.
Now comfortable with the machine's operational status, and foreseeable future/tenure, I'll get it a good douche bath with the steam cleaner next week to make things more conducive to a nice working atmosphere. Couple of neighborhood kids need a job so going to have them remove the sheet metal enclosing the engine, and radiator surround, then sandblast the machine clean and get it painted. Hopefully with the boom elevation problem solved, I can extract the cylinder and have it rebuilt this next week too:
I need this lift to reinstall a panel taken off my building, (in the upper right of the photo) due to recent high winds. You can see the gantry I'll use to support the boom while I lift the cylinder out with my skid steer:
At the ready once the machine is cleaned and painted I have enough SOOW wire in quantity to rewire the machine complete. Also have all new P&B relays, sockets, circuit breakers, main disconnect switch, and several toggle switches to replace originals. So much of the original hardware is fragile from exposure over the years so better to rebuild this way and know what I've got in the end.
Really appreciate the assist "Off".
Thanks,
