    New to me 1974 TD8E Support Questions

    Sounds like you are in for a lot of maintenance. :) I expect what you have are 2-12 volt batteries giving you 24 volts rather than 2- 6volt batteries. 24 volts is much more common. At least from you description it starts and runs. It could be after sitting so long the steering clutches are...

    Fix it or put it out to pasture?

    If what you describe about the engine and transmission is as bad as it sounds, it looks like a lost cause. It might be affordable if you had the time, tools, money and skill to repair. But lacking those I would suggest seeing if you can sell it for what you can get or possibly some trade value...

    Critters making homes in your dozer

    Yes, I have to watch out for the Hornets in Spring and Fall. I have gotten stung when going to operate the dozer not knowing they had created a hive. Mice are constancy nesting and I will toss in some rodent poison every year into the engine area and battery box area.

    Here is the priming sequence for a 1981 D31 Not sure what yours is but the steps will be similar.

    Your thoughts on clearing right of way

    When you push a tree down, ride it down all the way. This will disentagle it from surrounding trees. You do need to select the direction to minimize hitting directly other trees. Than push out the stump in the same direction for a few feet to separate it from the ground. Before pushing other...

    Don't know how close it is to the D31 that I have but here is a Thread that I had when mine needed work. https://www.heavyequipmentforums.com/showthread.php?19175-Stuck-Track-Adjuster-Komatsu-D31P-16&highlight=

    Section for komatsu d20,21 and similar grey market dozers

    Could work, but I think it would be better if the unit was set to work like it was designed with just something else in place for taking up the slack. There should be some room on the push out rod for cut out and insertion. I have never tried doing this so it is just total brain storming. If you...

    You will want to leave the spring so that the idler can move back with loading. A bottle jack will not work in a horizontal direction only vertical. It would take a ram like you see on the 10 ton manual wood splitter that HF sells. Or heck one of those short rams from a porta power type kit...

    Just a thought. Use a horizontal hydraulic jack/ram between the spring and front idler yoke. You would have to cut away some things or you might even come up with a simple screw and pin setup. So long as the spring is left in to move for shock take up, something could be made up I would think...

    Couple pics of my little machine..in an odd place.

    Thanks for the story JDDozerman. I have been fortunate to avoid crippling injury (52 years old now) in no small part from people that relayed stories of disasters like yours. Young people especially need to hear how quickly things can go wrong. That way they have it in the back of their minds...

    Asking Price for a JD 450J LT

    Sounds like a nice dozer. The problem as I see it is not what the dozer might be worth but finding someone to buy it. As you get closer to Winter, equipment loses its appeal to buyers since they have less work until Spring comes. Plus the economy is in the dumps. I am sure you can look through...

    Komatsu D31P-16 Engine rebuild.

    As a follow on: I got the head rebuilt it was fairly inexpensive at the local Auto machine shop. Only $125. The gaskets total were $350 and with new coolant and oil plus sundries I finished out at $700. Got everything back together yesterday and this morning. This was not a easy job since...

    Komatsu D31P-16 Engine rebuild.

    Well the head is off but nothing obvious jumps out at me for being wrong. The head gasket was not blown. I am going to take it in and get the valves done on tuesday. Hopefully, when I put it all back together it will be mysteriously fixed and no more exhaust leak from the breather valve (plus...
