Shuttle FZ-G Thrust Washer Replacement - HIROBO HI0402618  [HI0402618]

Shuttle FZ-G Thrust Washer Overview

The HIROBO HI0402618 is a replacement thrust washer designed for Shuttle FZ-G shuttle assemblies used in RC helicopters. It functions as a consumable interface between rotating parts, helping preserve correct axial spacing and limiting direct metal-to-metal contact within the shuttle mechanism.

Compatibility is determined by the Shuttle FZ-G designation in the part name. Fit this washer when rebuilding or servicing a Shuttle FZ-G shuttle assembly to restore original clearances or to swap out worn washer elements found during inspection.

Installation notes: clean all mating surfaces before fitting, confirm alignment of the shuttle components, and assemble without introducing lateral preload. Tighten fasteners in stages and verify free rotation of the shuttle parts after assembly. If you notice binding or excess play, recheck the stack order and the seating of the washer.

Maintenance role: this washer is intended as a straightforward replacement item during scheduled service. Inspect for wear, scoring, or surface deformation and replace the washer if any damage is present. Regular checks help keep axial spacing predictable and shuttle performance consistent.
