Hitachi 337126 Spare Part - CARRIER

Original Hitachi carrier — part no. 337126 — direct replacement for the gearbox carrier in compatible 14/18 V Hitachi/Hikoki cordless driver/drill models. This small but critical component locates the planet gears inside the gearcase and mates with the ring/pinion assembly to transmit torque cleanly; it’s supplied as a single genuine Hitachi carrier (part 337126) so you replace the worn or damaged carrier without changing the whole gearbox.

Examples of models this carrier is used with include Hitachi/Hikoki DS18DGL and several DS18/DS14 series cordless driver/drill variants such as DS18DJLSCZ and DS14DJL (check your model’s exploded parts diagram to confirm fit).

Why this part matters: a chipped or deformed carrier will cause rough gearing, noise and accelerated wear to planet gears and ring gear — replacing the carrier restores correct gear alignment and smooth operation. Fits into the original gearbox mounting points and is supplied as the original Hitachi replacement part; ideal when you just need the one component to get your tool back to working order. Hitachi parts like this carrier are exact-match replacements produced to the tool maker’s specification.
