Why this bucket linkage hub matters
Pins, bushings, seals, spacers, bolts, and related wear hardware are often easy to confuse across nearby pivot points. The same machine family can use visually similar parts in different locations, and the same part number can appear under different diagram contexts as serial ranges and work-equipment packages change. That is why this page is organized around the actual diagram images and callout order instead of broad category assumptions.
