Bucket Tips

(1) Usable
(2) Replace this bucket tip.
(3) Overworn Check the bucket tips for wear. If the bucket tip has a hole, replace the bucket tip.The loss of bucket tips can often be attributed to the improper installation of the retaining pin into the tip and the adapter. Bucket tips are lost more frequently on excavators because the tips are closer together. Inserting the pin from the correct side (right side) of the adapter is difficult due to the small gap. More clearance can be obtained by installing the pin through the tip and the adapter from the left side, and then by driving the pin against the retainer. This procedure will often cause the spiral retainer to become distorted, resulting in either a loss of retainer grip or an increased difficulty in removing the pin.

Improper installation
By driving from the right side of the adapter, the retainer is properly supported by the counterbore of the adapter. This procedure will show that the pin chamfer is centered in the inside diameter of the retainer more clearly.
