Hitachi 340-542E Spare Part - Stator Ass'y 220v-230v

Original Hitachi stator assembly, part number 340-542E — a direct-fit stator for Hitachi/Hikoki 220–230 V rotary hammers. This complete stator assembly arrives ready to mount (pre-assembled winding and laminated core) and is the correct replacement for the DH40 series models DH40MR, DH40FR and DH40SR.

The unit is listed as genuine Hitachi (Hikoki) spare part  340-542E , so you’re getting the original Hitachi part designed for these machines. It’s specified for 220–230 V machines and matches the original electrical spec and fitment of the factory stator.

If your hammer shows motor winding failure, burnt windings, or no-run/no-start symptoms localized to the stator, replacing it with this 340-542E stator assembly restores the original motor geometry and clearance tolerances required by the DH40MR/DH40FR/DH40SR toolset.
