    Looks like I finally need to replace the drag chain on a Meyer/Diamond MDV spreader. The current one is too loose and I cannot tighten it anymore. Any tips on how to remove the old one and put the new one in?

    Grinder to cut off the old one. The new one will have a master link on it that ables you to put the chain on the spreader

    Thanks, what I was looking for was tips on getting the new one pulled thru. Such as, can I attach the new one to the old one and run the conveyor and have it pull it thru?

    I just used a rachet strap and feed it through and pulled the chain thru, very easy

    Just remove a link or two and put in another master to shorten it up. No need to replace unless its worn out.

    I wasn't sure I could remove links. If I can, then that would save about $6 or 7 hundred bucks. The problem is that I can't tighten the tensions anymore. The chain touches the bottom in the first 3 or 4 inches back from the front. Manufacturer says minimum of 8" and maximum of 20".

    THANKS

    Site unseen, never worked on one but I'd imagine you could loosen the tensioners up to a point where you can cut a few links off and have more then enough adjustment to snug the chain up to proper tension.
     
  8. Yes take a few links out will work. We just did that on a few of ours

    OK...managed to remove a link and get it tightened back up. I think I have the drag chain a little too tight now though. Chain will only "jerk" forward an inch or two when conveyor is turned on. I will loosen off the rollers a bit and see if that fixes it.

    Make sure your Clutch belt is tight

    Does the chain flex ok

    I did put a new belt on as well. I don't think the belt is the problem though, when the clutch is engaged and the drag chain won't move, the belt stops turning as well. So its not just spinning on the clutch, that's why I think it is not a belt problem.

    Grab the spinner and spin it to make the chain move
    If chain moves easy 2-3ft then problem might be somewhere else something to check

    Will do. Thanks. If it doesn't move the chain 2 or 3ft, then you figure the drag chain is too tight???
