144787-5 supersedes older part numbers: 143718-1
Makita 144787-5 — Hammer Case Complete (genuine Makita). Replacement hammer/gear housing for the DTD170 impact-driver ; this is the full hammer-case assembly as shown in Makita’s parts breakdown, supplied to restore the hammer mechanism mounting and alignment (the separate hammer-case cover is listed as part 456710-1 in the diagram).
Fits: Makita DTD170 / DTD170Z.
Details to expect: sold as the complete hammer-case assembly (ready to replace the damaged housing section), with factory mounting bosses and screw locations matching the original tool, so the hammer mechanism and anvil align to factory tolerances when installed. The parts diagrams list the hammer case as a distinct assembly in the DTD170 breakdown, so you’ll receive the correct Makita-numbered housing for those models.
