    Yes I had a mechanic come out we checked the spool in the valve body then we’re gonna check the line to see if anything had gotten in it when the mechanic realized my open side hose was going to my return so when I changed my thumb sylonoid I mixed up 2 hoses. 600 bucks for him to tell me I...

    I have still been using my machine. I replaced all the fitting and hoses on the conversion and that fixed my leaking issue so off to work I go. I also equipped 120 with led lights all the way around. A stereo and a new belly pan. Happy digging my friends

    Not sure I unplugged mine and it fixed the issue with not being able to stick in and boom up at same time. But mine wasn’t bogging the machine it was just very slow or would almost stop. If the fuse is pulled it should be same as in plugging

    I think that’s the jist of it. Cheap fitting cheap o rings. I broke one just tightening it. But absolutely I have been out ripping stumps and ripping rock. Machine runs great. And remember before conversion I couldn’t even hardly use machine without it bogging down.

    So after running my machine for 10 hrs or so some or most of of the fittings on the conversion are leaking. Will keep you guys posted on what I do to fix it. If any one has any insight feel free to chime in

    Travel speed doesn’t change. Fuel gauge and temperature gauge work. No hr meter but that was a issue before. It seems like when pvc was plugged in travel speed would change. But I had to unplug it to get stick in to function properly

    So anyways I had a machinest look at my machine and is gonna build me a new pin. I have 6 new bushings coming for bucket stick and thumb. I also installed my manual throttle which was very easy to do and works great. Machine continues to work well with the conversion kit. Very happy

    Yeah after running machine a little I noticed that my stick in. Is very slow and sometimes can only do one function at a time can’t boom up at the same time. Thinking about putting more shims in conversion any input ?
