If you have ever repaired worn hinge points on loader arms or buckets, you know how difficult it is to cut off the worn area and try to weld on new hinge points while keeping everything lined up. A better way is to use the CLIMAX Model BB3000 Portable Line Boring Machine. If the holes are not badly damaged, you can simply weld them up, attach the BB3000 Line Boring Machine, and re-bore them to original dimensions. If the hinge points are so damaged that the entire area needs to be replaced, weld on new sections with slightly undersized holes, then quickly re-bore them to original dimensions while keeping everything in proper alignment.
