    TEREX 82-10 6v71T Detroit Revival

    I am in the process of trying to get a TEREX 82-20 running that has been sitting for maybe 30 years. We got it started after freeing up the racks and it initially ran on 2-3 cylinders all on one bank for a few minutes before taking off on the other side and sounding pretty good. Ran out of...

    Cat D6D Front Idler Part Numbers

    I have a Liebherr 731c that has a cat D6D (?) undercarriage on it and I need the shaft and bushings for the front idler. Can anyone identify these? Looks close to 5m005 and 2P8048 to me. But there look to be a few variations on the bushing. Thanks!

    Miller Bobcat 225NT weak arc

    Not sure if there are any welder guys on here but figured it’s worth a try… Bought a 225NT that the history wasn’t really known on. Runs great, seems to generate AC power great but when I go to weld it just can hardly sustain an arc. Makes 120 and 240v. The field coils on the rotor have about...

    We are putting a new undercarriage on a Liebherr PR731CL and the supports for the front idlers are worn pretty bad. Thinking of just cutting off the existing shim or wear plate , veeing out the steel and welding on a 3/8 or whatever we need thick plate of AR400 or AR500. What do people like to...

    Michigan 55A Spool Valve Leaking

    We have what I think is a Michigan 55A series 2 loader that has the spool valve with detents for the arm and an air release for the bucket. It started pouring oil out from the air release area for the tilt so we took it off and it basically exploded in our hands. Wondering if anyone has any good...

    TD20E general maintenance

    Hi everyone, We bought a TD20E some time ago that we are going through. Seems to be in great shape but I want to make sure we take care of it right to keep it that way. What should we do for the coolant system? Flush and replace or just test and put additives in? Any suggestions on...

    Liebherr 731C blade won’t work

    We just got a Liebherr 731c that had the blade chained up. We bought it from a lady who’s husband had passed and with him the knowledge of it went as well. Originally it wouldn’t move but it turns out it just leaked out a ton of hydro fluid from sitting for so long. It seems to move and run just...

    Liebherr 731C won't move - diagnosing or loading it on a trailer while dead

    Somehow I keep finding myself with dead dozers. I am thinking about buying a D600D Terex and a Liebherr 731C. Both nice looking machines with near new undercarriages and the price is basically scrap so I will not get burned too much. Basically, the owner sadly passed and no one around knows...

    Moving a non running TD20E

    I am looking at buying a TD20E that is currently non running. I think riggers will pick and load the machine onto a lowboy then I will be responsible for unloading. It's at a pretty tightly restricted facility so I cannot try to start it or really work on it or even grab pictures to post here...

    Michigan 55A air filter

    Long shot here but for the life of me I cannot find an air filter for this machine. I don’t have an official model number or serial number either but here are some pictures. Filter in the machine was the wrong one, looks like someone cut the fins and it’s about 1.5” too long. Also there’s...

    Hi, We have a Michigan 55 loader with a 3-53 Detroit in it. Not sure the exact series of the loader we can’t find a tag. After sitting for 15 years we got it out and used it a touch and after a few hours one day we started it up and it ran for 10 minutes or so and then would not move. It was...
