Hirobo HI0302018 14-Tooth SRB Pinion Gear  [HI0302018]

Notes on the 14T SRB Pinion Gear

This SRB pinion serves as an RC-scale replacement for SRB transmission assemblies and is manufactured to standard tooth spacing for reliable engagement. The 14T count changes the effective gear ratio and plays a key role in drive behaviour within the SRB setup.

Installation tips: check that the pinion bore matches your motor shaft and confirm the mounting method in use. Fit the gear by hand first to ensure it slides on straight, then tighten any set screw or clamp to the manufacturer's recommendation. Manually rotate the drivetrain to spot any misalignment or tight spots.

Mesh and tuning guidance: switching to a 14-tooth pinion will alter rotor rpm and torque compared to other sizes. Aim for a mesh with slight clearance that avoids binding while minimizing backlash. Small positional tweaks can significantly improve tooth contact; validate mesh with the system under realistic load when possible.

Care and inspection: remove abrasive particles from mating gears and avoid heavy grease that traps dirt. After each flying session, check for tooth wear, burrs, or deformation, and replace the pinion if you detect substantial wear to protect the rest of the SRB assembly.
