Hirobo HI2539030 M2.6x5 Replacement Guide Pin for Helicopter Parts  [HI2539030]

Guide pin overview and purpose

This HI2539030 guide pin is an RC-scale accessory intended for Hirobo helicopter general parts. It provides a locating and alignment function for small assemblies so that gears, shafts, and rotor elements remain correctly positioned during setup and minor adjustments.

Compatibility is confined to general Hirobo helicopter components listed under pins and general parts. Only fit this part where HI2539030 is specifically referenced in the parts documentation.

Fit the pin by inserting it into the matching locating bore so mating parts seat evenly, then secure with the assembly's original fastening method. After installation, check for any sideways movement and ensure the pin does not impede free rotation.

Consider the guide pin a service item: inspect periodically for bending, surface wear, or corrosion and replace it if it introduces noticeable play. Clean mating holes to help the pin preserve accurate positioning.
