    Stumps

    My method has been a version of that since I am working alone. Drop treees with saw and cut off the top. Leave the stump in the ground. Pile logs with machine near road, pile brush into pile to be burned. I can do these two steps now ( in the winter) easily when we are allowed to burn in...

    Stumps

    ripper Has anyone tried one of those rippers in place of a bucket? Combined with a thumb they appear to be a very slick setup (I have watched the videos out there). Of course the bucket works, but I have about 10 acres to clear hence a load of stumps. Looks like around 4K if you combine with...

    Track Speed Issues - Kobelco

    Progress Mr. Kobelco - Thanks for the help on the phone. Changed out the o rings on the front unit. Still need to inspect the back unit. O rings were certainly toast - dried and not working properly. Machine now seems to do OK in Reverse - still a difference in speed in forward. I...

    answers... Mr K - First, I have thrown up my hands on this one and have hired a local witch doctor to come have a look for 60 bucks an hour. He comes highly recommended so I will see what happens on 12/15 when he comes. In the meantime to answer your questions things run well just one track...

    kobelco sk 100 hydraulic problem

    i have the SK150 with this switch and since the throttle was disconnected long ago (now manual) I was figuring this switch did not do anything. I have not noticed any difference in the machine when i move the switch around but admit i have not played with it much. Is that true or is this...

    Track Speed Issues - Kobelco

    I have now switched the control hydraulics and the same track stays slow so the problem is not in the control valves. Also checked the tension on the tracks - no issue. I checked the motor before - nothing comes out the drain line, so no blow by. To me this leaves only the swing joint...

    Track Speed Issues - Kobelco

    dirthog your advice much appreciated. this machine only has 6000 hours on it so I am thinking I am going to go with the odds here and button this thing back up and save the joint rebuild for last resort. The lines have all been replaced in the past around the speed controls and one is much...

    Track Speed Issues - Kobelco

    removing slew joint OK guys, still plugging away on my track speed problem. Today I finished getting the motor in shape - no leaks and purrs like a kitten so i am psyched about that. So then it was on to the track problem. Checked the motor on that side an no fluid comes out the drain...

    Track Speed Issues - Kobelco

    well vice grips was not getting it done on the machine. This baby was stripped and tight. What worked on the bench was heat, a pipe wrench and a pipe on the wrench. Then she came. Guess I could have tried all that on machine - next time!

    Track Speed Issues - Kobelco

    i have been waiting for a gasket to get the engine going again. This machine was not well cared for before I bought it. When I went to change the oil, the oil drain plug was worn completely smooth. Shy of welding a bolt to it, there was no getting this off with conventional hand tools! So I...

    Track Speed Issues - Kobelco

    Chris - Very helpful advice, thank you. I like the idea of getting some data before taking things apart. I just got this machine and in the middle of getting the engine back together after repairing some minor oil leaks. Should have that done over the next couple of days. I also just got...

    Track Speed Issues - Kobelco

    thanks CPS - can you explain the logic around the motor test (not sure what the small line is vs the larger lines). Would like to understand it. If I crawl under the center of the machine and look up at the cylindrical unit that the pipes are distributed from - is that the slew joint? Is...

    Track Speed Issues - Kobelco

    I have a Kobelco SK150 MK IV that I recently acquired. I am new to the world of heavy equipment so bear with the stupid questions. This machine has an issue with one track running slow - maybe 70% or so of the other track. This is a problem on both high and low track speeds. At the advice of...

    "High Pressure" Grease

    I recently bought an excavator and the grease spec says to use "high pressure" grease No. 2. All the number 2 Moly based greases I look at do not mention high pressure. Is a standard Moly based No 2 grease OK suitable or should I be looking for something different. Happy to buy a case or so...
