We are currently experiencing substantial delays with Hitachi/HiKOKI and Metabo spare parts due to the two brands merging warehouse. At this moment in time we are unable to provide confirmed delivery dates on out of stock parts, for any urgent requirements please contact us prior to ordering.
Original Hitachi Motor Assembly — part no. 887446. This is the complete motor assembly used to drive the firing mechanism in select Hitachi/Hikoki cordless nailers; it’s the same unit built with metal and engineered polymer components around a robust electric motor core and includes the motor housing, mounting flanges and drive shaft needed to restore proper cycling and actuation.
Fits known models such as NT50GS and NT65GA (and is also listed for GBNF1850 / GBT1850K on Hitachi/Hikoki parts listings), making it a direct replacement when your tool is sluggish, fails to fire consistently, or won’t actuate.
This original Hitachi part supersedes the older reference 886662, so you’ll get the updated motor assembly designed for correct fit and function with the above tool — a practical option when repairing a single tool and returning it to reliable operation.
If you’re stocking genuine Hitachi spare parts for a repair, part 887446 is the motor assembly replacement to restore drive performance and consistent fastener delivery in the compatible nailer models listed.
