Hirobo Eagle Freya Counter First Gear Shaft HI0414168 DTDS  [HI0414168]

Counter first gear shaft suited to Eagle Freya models

This Hirobo HI0414168 counter first gear shaft DTDS is an RC-scale replacement component for the Eagle Freya helicopter parts list. It serves as the intermediate shaft within the counter gear train and is installed to re-establish correct gear mesh after wear or impact.

The overview highlights fitment and intended use rather than numerical dimensions; technicians should regard the shaft as a direct replacement for the Eagle Freya counter gear assembly. When carrying out service work, verify the shaft seating and assess bearing and mating gear condition to prevent binding and uneven wear patterns.

Fitting procedure: remove the rotorhead and gear cover to access the counter gear train, inspect mating gears for damage, insert the shaft into its bearing bores, confirm axial play meets the model tolerance, and rotate the assembly by hand to ensure smooth engagement before full reassembly and testing.
