Kyosho IF410-46C - Spur Gear 46T for INFERNO MP9/MP10  [KY-IF410-46C]

This Kyosho IF410-46C spur gear is a direct replacement part for the INFERNO MP9 and MP10 series, specified at a 46T tooth count. It is an RC-scale drivetrain component intended to restore or maintain the original gear mesh and overall drivetrain geometry.

Compatibility is focused on INFERNO MP9/MP10 platforms that use a 46-tooth spur gear as part of their stock drivetrain layout. When replacing the spur gear, check pinion engagement, centre differential clearance and bearing condition to ensure smooth operation and even wear across the gear teeth.

On setup and tuning, the 46T spur gear serves to maintain the stock gear ratio when paired with different pinion gears, allowing predictable changes to acceleration and top speed without altering the chassis mounting or gearbox spacing. Use correct shims and confirm backlash is within the chassis manufacturer's recommended range.

Installation notes: remove dressing or burrs from mating surfaces, verify the motor pinion is secure, and inspect surrounding bearings and gearbox seals while the spur is accessible. Routine inspection prevents accelerated wear and keeps drivetrain losses minimal.
