The Makita 6012HD Cordless Drill has had several service changes over the years. Due to these service changes, we do not list figure numbers 3, 6, 38, 40, or 55. Replacement of these parts may require replacement of other components within the tool, and we recommend calling us if you need to replace these components. The service changes are also listed in the "Tool Info" tab above the diagram, and the parts listed there are available for purchase.
