Hirobo HI0402595 Replacement Pulley for Shuttle SE Tail Assembly 35T  [HI0402595]

Shuttle SE Tail Pulley Details

This pulley is supplied as a service replacement for Hirobo Shuttle SE tail assemblies and carries the model number HI0402595. It features a 35T tooth profile used in the tail transmission path.

Fit this pulley during scheduled maintenance or when worn teeth reduce engagement accuracy, helping to restore expected alignment and drive performance in the tail system. It is intended to support common maintenance and tuning workflows for electric RC helicopters.

Installation guidance: gain access to the tail case and remove the old pulley according to your model's instructions, mount the HI0402595 on the tail shaft, confirm correct tooth seating and alignment, then close the tail case and confirm smooth rotation. While working, check bearings and linkage for wear to maintain reliability.

Service note: replacing the pulley affects how the tail drive engages; recheck tail centring and pitch after replacement and perform cautious ground testing to fine tune behaviour.
