    Front idler flange height measuring 0.60 (new)
    Top roller diameter measuring
    6.00 (new)
    Bottom rollers measuring
    6.85-6.75 20%-0% life
    Idk if this is my problem but I don’t think new rollers will hurt anything except my wallet.
    The book tells to shim the front idler wear plates to .06 and that is all, so they want the idler pretty much down on the track frame, but there is no procedure that I can find center the front idler to the sprocket? It has shims on each side under the “thrust plates” I believe the book calls them, but the only instructions I see are to put the shims back like you found them? It looks like at the moment the shims are split, the same amount on both sides, but should I be checking to see if that has it in line with the sprocket? And if so how to I go about doing that?

    stringline under the bottom from sprocket to idler and then over the top if the carrier rollers on this model are adjustable to adjust them and measure center of sprockets side to side and center of idlers side to side measurements should be the same this last should be done after making sure the roller frame pivots are tight to keep it from toeing in and out.
    Question someone else might know a long track has 6 bottom rollers and wouldn't a lgp have 6 also

    Hatch I know what you mean thinking the lgp would have 6 rollers but i don’t believe it does, I think they came in a standard track, wide track, and lgp, then long track, and the long track is the only 6 roller frame, the others are just different pad widths, with the wide track and lgp having the wider crossbar and dead axel to move the frames out for the pads to clear.
    Somebody feel to correct me if I’m wrong on this

    In my world they are the same thing.
    But the only way to know about JD's TD8g would be in an OEM parts book.

    Boy you sure like doing under carriage the hard way.
    I'm getting old enough I don't like crawling under little tractors so I jack the tractor up ,split the track and take the track frame off.
    Turn the track frame over and set it on heavy steel saw horses, much easier to work on.
    When you put the new rollers on you can center the front idler.
    When you put the track frame back on you center the drive sprocket to the back roller.
    Looks like you have too many shims in the idler wear strips.
    Good luck
    Bob
