Original Makita Change Lever Assembly — part no. 184678-8. This is the complete mode‑selector/change lever assembly used to switch drilling/hammer/drill+hammer functions on compatible Makita rotary hammers; the assembly includes the change lever complete (part 153289-0), cap (417628-1) and the updated clutch cam (part 324469-7 — old part number : 324152-6)

Fits the Makita HR2020/HR2021/HR2022 family and the HR2440/HR2440F/HR2441/HR2442/HR2445 series as a direct replacement — a genuine Makita part designed to restore reliable mode selection and eliminate slipping or a melted selector pin by replacing the complete change‑lever assembly if required. This original Makita item is listed in Makita spare parts references for these models.

Why buy this part: it’s a drop‑in, factory‑specified replacement that restores proper mechanical engagement of the selector cam and lever, preventing intermittent mode changes and ensuring the tool functions as intended. Suitable if your rotary hammer’s selector is worn, cracked, or the pin has failed; sold as the single, genuine Makita assembly (184678-8).
