    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...

Long story short we have no idea what the history of the machines is - don’t know if the torque converters were ok or no. We tore into one today and it looks ok to...

    We are working on rebuilding a 3306 for our 977 and got into trying to install the sleeves today and noticed 1. when we drop our sleeves in we have about -0.032" or protrusion. That is, the sleeve is not protruding like it is supposed to, it is actually sunk in the block over 30 thou. I know...

    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...

    Michigan 55 Torque Converter C272

    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...

    CAT 977L Torque Converter Leak and Milky Fluid

    Hey Guys, We have been making steady progress with the two 977Ls that we bought for scrap. We got the one motor free, put the head on from the other machine with the bad bottom end, and actually got it started. Seems to run pretty well. Immediately it started pouring fluid out of the TC that...
