Aftermarket Titanium Main Shaft for Mini Inferno

The TMIF1237 is a 37mm titanium main shaft intended for the Kyosho Mini Inferno transmission, supplied as 1 pr. It locates the spur and pinion and supports the gearbox or differential components within the case.

To install, remove the transmission cover, extract the old shaft with its retaining clips and bearings, fit the replacement into the existing bearings, and refit any circlips or set screws following the chassis guidelines. Confirm smooth rotation and correct mesh before closing the gearbox.

Used as a tuning upgrade, this titanium shaft provides higher stiffness and increased wear resistance compared to some stock materials, which helps keep gear engagement consistent during frequent running. Always check layout compatibility with your current bearings before fitting.

Can I reuse my bearings with TMIF1237?

Most users reuse the existing bearings if they are in good condition, but inspect for wear and replace if there is play or roughness.

Should gear mesh be adjusted differently?

Set mesh as you would for the original shaft; check for even contact across the spur tooth face and adjust shims or pinion position if required.

Is titanium worth the cost for casual running?

If you plan frequent running or hard use, titanium can extend service life and reduce drivetrain tuning needs; for light hobby use, benefits are smaller but still noticeable.
