    Excavator experts?

    I'm welded to a 1.8t cat currently (Very keen to get back into the 12t) and I have broken it again.

    I went to tension the track and the grease nipple is not in line with the port. I can't seem to shift it, it has slipped down. Now I am at a loss. I need to take the track off to get the guard off, and I need to let the grease nipple go to get the track off.

    What has happened? Where I am about to go, I have no desire to throw a track. I had enough fun getting it to flat ground last time.

    desperate way is if you can get a cold chisel on to side of grease nipple and snap it off to release the grease .

    Yep either way you need to get the nipple out, undoing preferable obviously. Odd that the cylinder has rotated?

    Scrounged an old flat can of degreaser and I can see better. I think I can release the nipple through the port.

    I think I will track it to the workshop.....

    I'm going to bash it with something. If anyone wants to tell me this is a bad idea you have between now and when I come back with a chisel and BFH.

    Not trying to tell you how to suck eggs but rotate the bucket 90 deg, lift up that side of the track off the ground and rotate the track half a dozen times to see if it loosens up. Generally the track adjuster slides in and out along rails inside the track frame, the cylinder ram could be stuffed and jammed or there maybe a broken track adjuster spring.

    Its not a major job to repair but if you are out in Bumfuck Oamaru that's your main problem. Otherwise use the BFH and start from scratch.

    I have know idea how to suck these eggs, I taught myself how to operate excavators. I often wonder (like when I'm on a steep slope with the tracks tipped forward stuck on the boom) what it's like to know what you are doing.

    As it still tracks Ok I will break the news to the boss and put it on the trailer.

    I don't know mostly drove bigger ones, haven't seen that before. Just remember you don't want them too tight anyway, they tighten when fill with loose dirt.

    maybe try a bit of wire or rope around grease nipple and lift that side up off the ground to take weight off the track and you might be able to pull it up.

    300winmag is correct

    Elevate that side and rotate the track back and forth in the air

    The ram will then self centre in its channel

    I tried that. I will try it some more. Is there anything I can lubricate?

    Is this something a rough country type could cause with a shiny new 18v Milwaukee grease gun?
