harleridr  <div>your track pins have a knurled end and a non knurled end, you can take a small phillips screw driver and use the tip to push the pins out, opposite to get them back in, I used the side of a pair of bent needle nose pliers, I push the pin with my fingers almost to the end and the pliers for the last 1/4 inch or so.</div><div>Actually quite simple. you should have spare track links and pins in the box your tank came in.</div>
