Makita 325899-5 Crankshaft HM1111C

Product Description

The MAKITA 325899-5 is a OEM replacement crankshaft designed for use in the Makita HM1111C rotary hammer. The crankshaft is a core internal engine component that converts reciprocating piston motion into rotary output, driving the tool's hammering and drilling action. This part is installed by qualified power tool technicians or experienced tradespeople during major internal rebuilds or after mechanical failure of the original component. Sourcing a direct OEM replacement ensures proper fit and maintains the mechanical tolerances required for reliable tool operation.

This crankshaft is specified for the Makita HM1111C rotary hammer, a heavy-duty demolition and drilling tool commonly found on commercial and industrial jobsites. It is typically replaced during overhaul service when the original crankshaft shows signs of wear, scoring, or damage resulting from extended use or inadequate lubrication. Proper internal component replacement extends service life and restores full tool performance.

Installation Notes

Crankshaft replacement on a rotary hammer requires full disassembly of the tool's gear housing and should be performed by a qualified power tool service technician. Disconnect and de-energize the tool completely before beginning any internal service. Refer to the Makita HM1111C service manual for correct assembly sequence and component orientation.
