    The 7775 project

    Today I started on a new project. A John Deere 7775 was brought over for me to do some work on, and I can say it needs it!
    Tires do not match, one new, one 5%, two 30% tread. The poor drive-train must look awful.
    Ignition switch does not cut the engine, you have to put it in park and jamb it in drive to kill it.
    Needs oil changed bad, hasn't been changed in at least 200 hours
    Pins have a LOT of slop in them from many many hours of run time (supposedly 7k hours on this machine)
    QA plate has one locking pin that sheared inside the shaft, to remove the bucket you tilt it all the way forward and use a chisel & hammer to push the pin in.
    The seat had seen better days, today I got that swapped out
    All of the safety locking devices for the pedals have been removed, the pedals are always live when you get in and out of the cab
    When the key is turned off the computer stays on and drains the battery, I switched it to service mode (separate switch) so hopefully the battery wont die.
    It does run and operate, it doesn't have much power though, it is not capable of filling the scoop with gravel and it bogs a little when you make sharp turns.
    In my case, I will fix a few things, mainly I need it functional so i can sell it for the customer, he wants to upgrade to a skid steer like my 317, something more reliable.
    I will post as I make progress, so far my Grandpa and I have only swapped out the seat which was a project all in it's own.
    More to come!

    Thanks Kenny! Yes, the owner wants me to keep track of my hours as well, so far I have an hour and a half in it. It was definitely rode hard, it was a former manure scraper on a dairy farm back when it was new. It was beat 10 years ago!

    Made some more progress on the 7775 this morning.
    Started off like this:
    Went out to start it and no start. So we jumped it with another skid steer and got it going. Grabbed the bucket and brought it over to get it pressure washed. Once I started washing it I got mud/manure everywhere. However after an hour and a half I got it pretty well washed. I also washed out the bucket which was packed with manure. Finally, I put the seat back in (took it out so it would stay dry) and tried to start it. No go again. Tried hooking another battery to it, still no go. So now I have it on the charger for a while, hopefully i can get it started so i can clean up the muddy mess on the pavement. For now, I am going over it to determine what parts I will need for it, I did notice one hydraulic hose that badly needs to be replaced, the muffler is loose, the roll pin for the left side locking pin (to lock the bucket on) is missing, thus it cannot be locked/unlocked without a chisel and hammer. The ignition switch needs replaced, the fuel gauge is not hooked up. It goes on and on. More to come later!

    I finally got it started again. Moved it out of the way so I could clean up the mess on the pavement and lifted the boom so I could get to the battery. I also did a good walk around to see what all this thing needs in parts. You can see that I am missing the groove pin for the bucket lock. Also, for those who thing 1/16" is a lot of slop, look at the pins on the lift cylinders! I can see through to the other side! This machine also has a considerable amount of rust, not a big shock as it was a former manure scraper on a dairy. So far on my parts list:

    Ignition switch #MG641833
    Oil/Oil filter #M806419
    Fuel Filters #T111383 & #AE29052
    Hydraulic Filter/fluid #M124541
    Air Filters (Primary and Secondary) #RE45825 & #RE45826
    Roll pin for bucket lock #25H829
    Positive+ Battery Cable #MG86502198
    Plug #MG618118
    Grease

    This is just the start list, I did notice some hydraulic hoses in pretty sad shape but I'm not entirely sure how you would replace them as they go down under the cab. Therefore I cant see getting to them without removing the boom and the cab.

    Well, this morning I went back to work on the 7775. Today it fired right up! Maybe the battery just needed to be charged. Anyways, something that really bothered me was the loose muffler. So I decided to tighten it up. Turns out the top left nut has stripped the threads on the nut and wouldnt allow for it to snug up. However there were good threads further back, so I put a second nut on it. Ended up shearing the bolt.

    At least I got it tightened down, no more rattling muffler.

    My next step was cleaning around the engine. I don't like the thought of pressure washing the engine so I used the air compressor to blow the dirt out of the engine compartment/radiator. I can say it worked out pretty good, it isn't super clean but the majority of built up dirt is gone.

    Next on the list was doing something about the right side tires, one was close to bald and the other was brand new. Fortunately I was able to swap that out with the 7775's spare which is also new. It wasn't as easy as I had expected, the rim was on so tight that after removing all of the nuts I had to use a 6 ft bar to get it pried off the hub.

    With no new parts on hand yet, I decided to do something about the grease build up around all of the pins. It took a while but I got it pretty well cleaned up. (example shown)

    Today I finally picked up some stuff from John Deere and placed an order for numerous other parts (hydraulic lines, ignition switch, hydraulic filter, etc.).

    I also uploaded this video of the 7775 running yesterday, it sounds much better with the muffler tightened down.

    So as for today, I have yet to decide what to do. It is snowing and cold, not ideal weather for changing oil outside. Wish I had a heated shop to pull the 7775 into, but it is what it is.

    Today I made more progress on the 7775. It started right up this morning (28*F outside) and I let the oil warm up before I shut it down. Next I grabbed the new oil and put it inside by the stove to warm up as well.

    Pulled the oil plug and drained the old oil out. I also pulled off the old filter and replaced it with a new one. Then refilled with fresh oil.

    Next I lifted up the seat and checked out the main linkages bellow. The plate that connects to both control arms has 4 small screws that attach the arm linkage to the plate. Those 4 screws were loose which meant there was slop in the controls. So needless to say I tightened them down. Once I started it back up I noticed it now creeps in reverse on the left side. Since the left side brake is gone it will drive backwards in a circle if you were to leave the machine unattended with the park brake on.

    And finally, I replaced both of the fuel filters. The mess of fuel lines under the second filter made it messy to remove, however the diesel fuel made it much easier to clean the dirt off the top of the fuel tank.

    Well, after recently taking a new job I got back to working on the 7775 today. A little while back I swapped out the ignition switch, still will not shut off at the key. So I asked a technician down at Deere where to look and he suggested cleaning the ground cable between the cab and the frame. So today i did, still no change. I cant say Deere put the ground cable in the best place, it easily collects dirt and moisture plus it is very difficult to get to. After further inspection the wiring through out the machine is good, so that leaves a solenoid to be the culprit to not shutting down via the key as well as displaying stats to the computer and gauges.

    Next I flipped the seat up in the cab and checked out the linkage to the left side brake. The linkage looks good, my theory that the brake must be worn must be right, that or something within has broken at some point in time.

    I also managed to remove the side fenders to access the hydraulic hoses, tomorrow I plan to swap the bad hoses (outer layer of rubber is long gone, wire mesh is exposed and some is corroding). I also plan to flush the hydro fluid and replace with fresh fluid as well as a new hydro filter (Deere wa$ very proud of that hydro filter). The area around the hoses was loaded with dirt and debris so i gave it a good cleaning and used the air compressor to clean around the fittings that the new hoses will attach to.

    I also installed the new groove pin in the front left QA lever which is so badly corroded that the pin is not tight, it is loose enough to fall out however since the bucket is almost never removed from the machine I don't see it being cost effective to replace the entire QA system for the convenience factor. The owner of the machine recently stopped by and likes how the machine is coming along so well that he has decided to keep it. Wish me luck for tomorrow's project, the hydraulics...
