OC: Hydraulic Cleaning Questions

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic


   The other day, my neighbor gave me two Grove Silage wagons.  These are Hydraulic Drive unloaders through the tractor remotes, and can unload from Front, or the rear.  I want to test the hydraulics, but on one of the wagons, the hose ends are missing.  I am uncertain how long they have been missing, but am worried that there might be moisture, or mud wasp nests in the hoses.  
I plan to completely drain the systems, put in new oil, and then test them.  

But I am wondering if there is a way to protect the tractor that is going to run the hydraulic lines.  Just incase the drain does not removed all foreign objects.  Is there a way to put something inline to clean the fluid, or are there other methods?  

Thank you,
John

	One way to protect the tractor would be to have the fluid drain into a bucket instead of going back to the tractor. The other would be to have a portable hydraulic 'power pack' ( pump/reservoir/valve) and use it. Just be sure about pressure.... Final method, borrow a 'green tractor' and see what happens....... Jay

	You are on the right track insects love to find an open fitting and make it theirs. Anything they carry in will lodge at the first tight place and in a small orifice or screen then you are kind of locked up. It might be less trouble than you think to open the lines and clean with air and look into the hoses and valves and motors. then flush with a little oil out of the tractor before reconnecting them. You can rig up a filter in the line that comes back out of the wagon before it returns to tractor. It is a little special but Most hydraulic shops can provide them. also they may know of a service that will come to you place and run them with a set up made for decontaminating systems.
