Hirobo HI2539030 Guide Pin M2.6x5 - Helicopter General Parts  [HI2539030]

Alignment pin details and use

This HI2539030 guide pin is an RC-scale accessory designed for Hirobo helicopter general parts. Its role is to locate and align small assemblies so that bearings, gears, and rotor elements remain correctly positioned during setup and minor tuning tasks.

Compatibility covers general Hirobo helicopter components listed under pins and general parts. Confirm explicit references to HI2539030 in your parts list before assuming fitment to a specific airframe.

To install, push the pin into the matching locating hole until mating parts sit flush, then secure using the assembly's original fastener or retaining method. After fitting, check for any lateral movement and ensure the pin does not interfere with rotating parts.

As part of maintenance, treat the guide pin as a consumable: check for bends, scoring, or corrosion during inspections and replace the pin if it begins to introduce play. Keeping mating surfaces clean will preserve accurate positioning.
