Description
Overview:
The Crank Pin 4 is a genuine Makita replacement part for the Makita HR5001C Demolition Hammer (OEM No. 323973-3). It is a precision‐machined steel pin designed to transmit motion within the hammer's crank mechanism, helping convert rotational drive into the repeated impact action.
