Description
Overview:
The Connecting Rod for Makita HMJ1812 Electric Breaker (MPN 142922-9) is a Genuine Makita OEM component that transfers drive motion within the breaker's impact mechanism. Made from durable steel with precision-machined bores, it links the drive to the ram/striker so impact energy is delivered consistently under load. Built specifically for the Makita HMJ1812, it restores correct clearances and smooth movement when the original rod is worn, bent, or cracked. The factory-matched form and dimensions enable a straightforward swap during routine servicing or repair, helping to minimise downtime. Using the correct genuine rod protects mating parts such as gears and bearings, maintains rated striking performance, and supports reliable operation on site for tradespeople, hire fleets, and heavy DIY use.
