Gerri the NVT Guru shows how to adjust boom wear pads to keep the boom stable. When pads rub unevenly, they can bind the centre section. The fix: shift the boom wing to move weight off the rubbing pad, then push down to confirm the centre stays still.

Part of boom stability is the wear pads here. They can actually cause some problems if they're rubbing on one edge and not on the other. What happens if they're rubbing there? That binds up with the centre and tries to move the whole centre rather than be free. To make sure it's adjusted correctly, you need to look at the wear side in there and look at the wear side in here. And in this case, it's rubbing on this side. So the boom would need to be adjusted so the boom wing is back a little bit to throw the center section forward a bit to take the weight off there. We just. When you test for this, push the boom down and make sure the boom centre doesn't move at all and you know you've got that adjusted properly.
