Upper Transmission Gear for XRB SR Models

The Hirobo HI0301043 is an upper main gear produced as an aftermarket replacement for XRB SR helicopter platforms. It serves as the top section of the main transmission gear and is intended to substitute worn factory parts to regain drivetrain reliability.

Installation notes: ensure the gear seats squarely on the main shaft, verify axial and radial alignment and inspect mating gear teeth for damage prior to torquing clamps. Replace any suspect bearings during reassembly to avoid premature wear.

Tuning perspective: fitting this upper gear can reduce gear-induced vibration and restore precise mesh, helping to improve stability and reduce noise during flight operations on XRB SR helicopters.

Will replacing the upper gear fix vibration issues?

If vibration is caused by worn gear teeth or a damaged upper gear, a correct HI0301043 replacement will often reduce those symptoms. Check bearings and shaft condition as well.

What is the material and expected durability?

The part is a machined aluminum alloy component designed for standard RC use. Durability depends on operating conditions and maintenance; avoid contaminated gear mesh and replace bearings when necessary.

How often should I inspect this gear?

Include visual checks in routine inspections and re-evaluate after any hard landing or unusual vibration event. Replace if pitting, scoring, or deformation is evident.
