I've been looking through threads and doing google search for a while now but figured I would just post up whats going on and see what responses i get. It seems there's some VERY knowledgeable people here that could probable direct me and help me out. So this will probably be a little winded but i'm going to try and provide as much info as i can in this initial post...
Purchased the backhoe and brought it home. Knew the front loader lift cylinder was leaking but didn't know how bad until i saw the puddle and line of fluid on the trailer. Got it home and ordered seal kits, figured if i'm doing one i should do both. Drained the fluid through a plug under the op-side of machine into a pan. Fluid came out like a milkshake looking substance. Removed the cylinder rods, leaving the housings on the machine. Re-did both with all new seals on cylinder and gland. Reassembled both and filled with fluid from tractor supply (I believe the premium hydraulic fluid)
Started up, operated the bucket up and down slowly to work the air out and then added another gallon of fluid. I will admit i did NOT check the level in any way shape or form, simply added back in the amount i drained out. Fired it up and everything seemed to work great. Started digging and moving dirt and rocks on the property.
Eventually using the backhoe i found the dipper cylinder start leaking pretty bad. Replaced with same seals, did not drain fluid just replaced what i figured i lost changing the seals. Continued digging and moving rocks and such until one day shortly after the bucket curl on backhoe line decided to burst. Pulled that off and replaced that and another line that did not look so good. No problems just took a little time working the air out of the system after this.
Continued using the machine and every so often noticed power seemed to be down or i was just getting used to it.
I then noticed when using the stabilzers that when i would raise the right one it operated fine (just leaks more and more) but when i operated the left one (When seated facing the backhoe) it will NOT raise at all unless i move another level along with it. Anyone ever see this before? I can move any other lever with it and it will raise but will not raise on it's own. It will go down and lift the machine (sometimes seems to struggle) just fine with that single lever.
By the way it has the stick setup from left to right: bucket curl, dipper in/out, boom up/down left outrigger, right outrigger.
The boom cylinder seals started leaking pretty badly then. I ordered seals from a different place on ebay and when they arrived and i went to do the job I noticed they were very different than the other kits i installed. I needed the machine so i installed them and reassembled. They did not come with great piston seals and the others seemed like crap. Well the one cylinder still weeps fluid out so i will be redoing them as soon as the pole building goes up.
By the way, that's what i'm mainly using this for is to excavate a site for a new pole building.
Well i cut the trees down and dug out two stumps, the third tree came down and i started digging the stump yesterday. When starting to dig i noticed the dipper was jumpy and operating in a jerky fashion when retracting the cylinder, when extending it didn't seem to have a problem but moved slower than before. Then trying to lift the boom it was jumping and shaking. I tried operating everything with no load to try and warm the fluid and help things out. It did get smoother but then came back a short time later. I noticed that it seemed to be down on power when all of a sudden i went to lift the boom and nothing happened, no movement. I left go of the stick and tried again, holding it open, the boom began to move and i got movement back. I continued digging and had power to even break roots of the poplar stump i was digging out (not small at all, tree was about 105' tall) but this came back 2 or 3 more times. I stopped digging and shut her off for the day before causing any further damage or problems until i get this sorted out.
Whew, that was long and i apologize but i wanted to provide the story and see what everyone thinks my problem could be and what i should do???
Thanks ahead of time for anyone that took the time to read ALL of this! :rolleyes:
