This part replaces the acrylic part for the Y idler. The front Y rod goes through the gap in the foot part and the adjuster block pushes onto the end of the rod. This allows the height of the rod to be fine tuned to remove any twist and allow you to get the bed level at the front. You will also need an M3 bolt I have used a cap head as can be seen in the picture and an M3 nyloc nut, this passes through the hole in the top of the idler bracket through the adjuster block and secured it with the nut underneath. You can then move the rod up and down by tightening or loosening the bolt.
