Shuttle SE Drivetrain Pulley Details

This replacement pulley from Hirobo, model HI0402593, fits Shuttle SE helicopter drive trains and carries a 20T tooth count. The tooth count defines mesh and gearing behaviour rather than indicating material strength or a load rating.

During installation check the Shuttle SE gear mesh, shaft alignment, and bearing condition. Remove the original pulley, inspect mating gears for wear, fit the new pulley with accurate axial positioning, and confirm unobstructed rotation before powering the airframe.

Install the pulley for routine servicing or when restoring drive accuracy after long-term use. Proper mesh tolerance and component condition reduce vibration and uneven wear, aiding consistent tuning outcomes.

How does the 20T tooth count influence torque and rpm?

The tooth count is one variable in the gear ratio calculation; a 20T pulley changes the final drive ratio and thus affects torque delivery and rotational speed. Consider it when planning tuning changes.

What are best practices to avoid vibration after fitting?

Ensure correct gear mesh, verify shaft and bearing health, and align the pulley precisely. After assembly, rotate the system by hand to detect any binding or wobble before test runs.

Can I use this pulley when changing gear ratios for performance?

Yes, the 20T tooth count will alter the gear ratio and can be used as part of tuning decisions to trade speed against torque within the drive train.
