    Seeking advice on buying an excavator for clearing land.

    I have an ex60urg Hitachi. ~16k lb machine. I use it to pull stumps on my property. If I had to do it again, I'd look for a machine at least double the EX60. My machine will do it, but it takes time. With 2.5 times the property, you need a bigger machine.

    EX60URG controls

    Ok, that makes sense. I wondered how the hell that worked (assuming the function works at all). I'll play with it tomorrow and see. I appreciate it!

    Hitachi ex60-2 power loss

    For the URG (and probably the OPs machine), there is a screen on the inlet of the lift pump that is probably clogged. This is the pump that has the little plunger on it to prime the system. The fuel line comes in on the bottom of the pump. There is a screen on the banjo bolt. You will need to...

    EX60URG controls

    Hi all, Early/mid 90's Hitachi EX60URG grey market machine. Runs and works, but need some guidance. I use it on my farm/homeowner machine. Not a business. As I'm still a bit of a noob when it comes to the components, can someone please educate me on what the button/switch in the picture does...

    Building Bushings for Hitachi EX60URG

    I have a mid 90's Hitachi EX60URG (grey market machine) that is in need of some bushings & pins in a few places. I can get some of the bushings and most of the pins online between Ebay and a couple of websites that I've found that list the part numbers. Some of them I've run up short and appear...

    EX60URG pilot filter and hydraulic gremlins

    Quick question. New to owning an excavator. Early 90's Hitachi EX60URG. Essentially an EX60-1 but with a compact counterweight (doesn't stick out much at all) and one of those funky booms that can be offset for digging next to a wall. When replacing the main filter and pilot filters, is it...

    EX60URG Final Drive issues?

    I have about 6 hours on the machine including quite a bit of tracking around. No leaks! I'll consider it job done at this point. Thanks to everyone that helped out!

    EX60URG Final Drive issues?

    One final update. I got the thing reassembled and installed it today. No leaks (yet)! Was getting dark, so just had my son drive it back and forth for 15 minutes. No drips. I used three liters of 80/90 wt from Napa. The manual just calls for 90wt, but very few places sell straight 90wt these...

    EX60URG Final Drive issues?

    The second one was... anticlimactic. Took 10 minutes to install. I did use the freezer suggestion and some denatured alcohol. This is the side that came out in chunks (the side that was so hard was intact) and I'm thinking that its just a shade larger opening. Talking to their senior service...

    EX60URG Final Drive issues?

    After a lot of hate and some rage, one of the two is installed. I was going to quit for the night, but couldn't let it go. The steel ring sticks up from the housing about 11.6mm / .45" evenly + .1 or .2MM. I have to go to the dealer tomorrow to pick up one of the M14 socket head cap screws, so...

    EX60URG Final Drive issues?

    One weird thing. Attached is a clip from my EX60 service manual (the EX55 manual says the same thing). The thing says to apply grease to be bore of the housing and to the outer part of the seal. With all the talk about installing the seal dry and/or WD40/silicone spray I'm a little confused...

    EX60URG Final Drive issues?

    Cleaned up the ring sealing surface on both sides and commenced to attempting to install the seals. Several hours of cursing later... I still haven't been successful. Unbelievably frustrated and exhausted. if the damnedable seal wasn't $377, I'd have sent it sailing out the doors of the shop. I...

    EX60URG Final Drive issues?

    Some details I suppose. I used M10 bolts as the pegs. I drilled and tapped the plate (1/2") for M10 after laying out the pegs (by hand with a divider). I had bought bolts that had an unthreaded shank portion. I cut the bolts off to give a peg that would stick out by the right amount. I was just...

    EX60URG Final Drive issues?

    For reference, here is the tool that I built to get the ring off. Turned out pretty well frankly.

    EX60URG Final Drive issues?

    Built a tool with pins and the top centering bar tool and got the damned thing apart. The oring on one side of the floating seal was in about a dozen pieces. With any luck, I can get it put back together tomorrow. All the bearings look pretty tight and there are small amounts of wear products...

    EX60URG Final Drive issues?

    Got the hydraulic motor out. The D ring seals are indeed worn out. You pull the complete motor by removing the six large M14 socket head cap screws (part 48 above). The allen is an M12. Had to go buy one. Minorly messed one up removing them (they were on there), but the dealer was happy to order...

    EX60URG Final Drive issues?

    Got the final drive removed. Had to buy a 36MM wrench to get the pressure hydraulic lines off. Didn't have a 12MM allen socket either to get the hydraulic motor cap screws broken loose. I'll pull the motor off tomorrow. Interestingly, the manual says to 'grease' the floating seal oring surface.

    EX60URG Final Drive issues?

    Always read the manual. The case drain is for 'pump leakage' and doesn't function as a return. The other pressure line (rear when driving forward) is the return line.

    EX60URG Final Drive issues?

    Pulled the leaking final drive yesterday. It wasn't as difficult as I was thinking. I was expecting a gush of hydraulic fluid out of the drain line - but it was more of a trickle. There doesn't appear to be a casing drain filter on this machine. Am I missing something? Was I just mistaken that...

    EX60URG Final Drive issues?

    That's what I was afraid of. I ordered a set of these Service plugs. https://www.amazon.com/gp/product/B07KKQ222H/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 I'll see how it works out... As I'm a relative NOOB when it comes to working on hydraulics, any MacGyver options that you have...
