    Nice job. Some of the dummies I work with wouldn't know what to do with the cab on the opposite side like the machines of today.

    Wow, awesome looking machine!

    I have a P&H H312. Owned it for a few years and it has paid for itself probably 5 times over. I used to drive it up the road to my house from the shop. One time a track link broke while at my house. Haven't driven it on the road since. Rigged the link back together. A month ago another link broke. I crutched the excavator into the shop. Now, my plan is to fix the tracks. It's going to be a lot of work. But, it needs it. While it's in the shop I am going to put some lights on the boom and under the house. Lots of odds and ends need fixng on this. The generator doesn't charge, the rotate brake doesn't work. Various pins are worn, cab heat doesnt work.
    I stumbled onto this site while searching for track parts. Any good sources for rollers and links?

    Here is my 1973 P&H H312 doing some clean up. The truck is a Brockway 361.

    Gosh, it seems whenever I mention my P&H the thread becomes a ghost town. Awwww, is my P&H too ugly?


    thanks,

    P&H = tumbleweeds blowing by and the sound of squeeky hindges on an old wooden fence gate moved by the wind.

    This is a 418 i found in a field one hour drive from where i live.By the look of it, is has'nt moved for several years.
    Not that long ago, i went back to this machine.I took as many pictures as i can of all the main components, along with some measurements of everything on it.
    Eventually, i am planning on building a scale model of it.
    Thanks for showing your 312.
    B-t-w, does anyone know if these old P&H had the attachment painted in black or yellow when new??
    Max.
