Product summary and purpose

This RC component, part number HI0403245 from Hirobo, is supplied as the replacement counter gear joint shaft for GPH 346 helicopter assemblies. It locates in the counter gear area of compatible GPH 346 gear trains and provides the rotating connection between gear elements.

Installation notes: fit the shaft into the counter gear assembly using the manufacturer's alignment points, check mating gear faces and runout carefully, and ensure bearings contacting the shaft are clean before final assembly. Use appropriate hex drivers and tighten screws in the sequence shown on your parts diagram to maintain proper alignment.

Service role: fitted when gear play or shaft damage degrades drivetrain smoothness, this shaft should be checked during setup for correct gear mesh and axial clearance while rotating slowly, followed by a brief bench run to ensure smooth engagement before operational checks.
