Product Description

Repairing worn hinge points on loader arms or buckets, can prove difficult when cutting off the worn area and trying to weld on new hinge points whilst keeping everything lined up. A simpler method 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 whilst keeping everything in proper alignment.
