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

Shuttle FZ-G Washer Function and Fit

The HIROBO HI0402618 is supplied as a replacement thrust washer for use in Shuttle FZ-G shuttle assemblies on RC helicopters. It sits between rotating elements as a consumable spacer that maintains correct axial clearance and helps prevent metal-to-metal contact inside the shuttle assembly.

Fitment is governed by the Shuttle FZ-G designation noted in the part name. Install this washer when rebuilding or servicing Shuttle FZ-G shuttles to recover original spacing or to change out worn washer parts found during checks.

Fitting tips: make sure mating surfaces are clean, confirm correct alignment of the shuttle parts, and assemble without adding lateral preload. Tighten bolts in stages and verify the shuttle components rotate freely after assembly. If binding or looseness occurs, re-evaluate the washer seating and order in the stack.

Tuning and upkeep: this washer is a basic replacement item useful during tune-ups. Inspect for surface wear, scoring, or deformation and replace if defects appear. Regular monitoring helps sustain predictable axial spacing and consistent shuttle action.
