Precision Wash-Out Locator for EX

Catalogued as HI0404137, this Hirobo guide pin is a corrosion-resistant steel component intended to interface with EX rotor head features. Its role is purely mechanical: to offer a dependable stop for establishing wash-out alignment and preserving consistent blade tracking during head rebuilds and setup.

Installation is straightforward. Find the designated seating point in the EX rotor head, insert the pin gently, and confirm the wash-out links travel freely without interference. Employ appropriate hand tools and avoid overtightening hardware to prevent deforming the pin or adjacent alloy parts.

When working on setup, use the pin as a fixed reference rather than a tuning element. It helps reproduce the same blade tracking positions after blade changes or servicing. During maintenance inspect for wear or bends and keep spare pins in your parts kit to minimise downtime.
