The Kyosho IG113-17 second gear is supplied as a compatible replacement for GT-series gearboxes. Its 17T tooth count makes it suitable where an identical intermediate gear is required for service, repair or setup work.
Installation: access the gearbox, note the original gear stacking, and check pinion engagement. Remove the existing second gear and fit the IG113-17, confirming smooth rotation and correct mesh before refitting the gearbox cover. Ensure all retaining clips and collars are restored to their original positions and that the motor pinion has proper clearance.
Effect on performance: this 17T second gear adjusts the intermediate gearing and therefore mid-range response. Pair it with appropriate pinion and spur choices to maintain drivetrain equilibrium. Replace worn bearings or damaged shafts to avoid excess noise and premature gear wear.
Recommended as a like-for-like replacement for gearbox maintenance or to restore intended drivetrain geometry after demanding use. Confirm compatibility with your chassis documentation before installation.
