3.Remove the new nose sprocket package's clips and fold back the top portion of the insertion card be- ing careful not to remove or disturb the components. See Figure 27.
Figure 27. Preparing New Nose Sprocket
4.With a flat blade screw driver in the bar nose rails, slide the nose sprocket assembly into position align- ing the 6 holes in the bar nose with the 6 holes in the nose sprocket assembly without removing the components from the card. See Figure 28.
Figure 28. Installing a New Nose Sprocket
5.Insert 6 nose rivets into the holes and then hold them with your thumb. Remove the screwdriver and slide out the insertion card.
NOTE:
On used bars the nose rails might tend to spread apart. Use a small clamp if necessary to hold the rails together.
6.With the bar and rivets solidly supported on a strong flat steel surface, carefully peen the rivet heads down with the flat end of a hammer. Be careful to only hit the rivet head. Do not hit the bar body; this will pinch the nose sprocket. Rivet heads must com- pletely fill the countersinks in the bar body and be snug and secure while still allowing the sprocket to freely turn. See Figure 29.
Figure 29. Replacing Rivets
7.Using a flat file, shave the rivet heads to a uniform height that is as close to the bar body as possible. See Figure 30
