MTX-4 2nd Gear Hardern Aluminum 23T - MTX4-0823 by 3Racing  [MTX4-0823]

23T Hardern Aluminum Intermediate Gear for MTX-4

This aluminum second gear is a direct-fit replacement made for the Mugen MTX-4 buggy drivetrain. Machined from Hardern aluminum, the 23-tooth unit functions as the intermediate gear in the gearbox and is intended for scale RC running and rebuilds that accept the same geometry.

Compatibility and function: the part meshes with MTX-4 gearbox components and works with the vehicle's spur and pinion arrangement to set final drive ratios. It is not a universal gear and should only be used in transmissions built to the MTX-4 specifications.

Installation tips: when you install the second gear inspect bearings and shafts for wear, set correct gear mesh and backlash, and re-check pinion alignment after refitting. Keep the original mounting orientation and torque fasteners to recommended values to avoid housing distortion.

Tuning notes: changing to this 23T intermediate gear shifts the overall ratio in small steps and pairs well with alternate spur or pinion sizes to tune acceleration versus top speed. As an aluminum gear it will behave differently to steel or nylon in wear and heat transfer, so monitor mesh and temperatures during test runs.
