Hirobo HI2530005 Pivot Bolt E Replacement Set for Helicopter Rotor Linkages, 2 pcs  [HI2530005]

Pivot Bolt E - Linkage Replacement

The pivot bolt E is a compact replacement pin intended for rotor linkage and control arm pivot points on Hirobo helicopters. Supplied as two pieces, this set provides a direct swap for worn or damaged pivot locations where a dependable, low-profile pin is required to restore correct hinge movement.

Fit this part when wear or play at a pivot point affects blade or tail linkage geometry. The component helps retain alignment between control linkages and rotor assemblies, contributing to steady control feel and making trim work more straightforward. It is designed for maintenance and repair tasks rather than structural enhancement.

Installation is straightforward for competent technicians: remove the affected linkage, replace the worn pivot bolt with the supplied pin, confirm free but secure movement, and reassemble. After fitting, inspect rotor and control travel to make sure there is no binding and that trim remains stable.
