Description
Overview:
The Crank Cap (MPN 455525-3) is a genuine Makita replacement part for the HR4511C SDS-Max rotary demolition hammer. It is a hard-wearing, moulded polymer cap (black) that seals the crank mechanism area to help keep dust and debris out while supporting correct lubrication inside the housing. By replacing a cracked, worn, or missing cap, you maintain smooth operation of the drive system and protect key moving parts from premature wear. Designed specifically to match the dimensions and tolerances of the HR4511C, it offers a direct, reliable fit with no modification. This small service part plays an important role in overall tool reliability, especially in heavy site conditions where vibration, impact, and abrasive dust are common.
