Bevel and pinion technical overview

This 3pc set is a direct-fit RC-scale drivetrain replacement for Axial platform gearboxes, addressing the differential output and motor pinion interface. Components are supplied in hardened steel #45 and the bevel uses a spiral tooth form that improves contact distribution and reduces localized stress under load.

Included parts: diff bevel gear 38T (1pc), pinion gear 13T (1pc), M4*2.5*12 screw pin (1pc). Note: the M4*2.5*12 screw pin is not suitable for the Wraith platform; when fitting to Wraith models retain the original screws supplied with that kit.

Service and installation guidance: verify correct mesh and backlash in the gearbox housing, confirm secure pinion seating on the motor shaft, and apply appropriate RC gear lubricant to the meshing surfaces. Due to the spiral-cut bevel profile, maintain precise axial alignment to prevent premature edge wear.

Compatible Models

  • Axial RR10
  • Wraith
  • Yeti(90026,90050,90068)
  • SMT10 AX90055
  • AX90057

Recommended when replacing worn diff bevels or upgrading drivetrain longevity; confirm screw compatibility for Wraith models and set gear mesh accurately for consistent performance.

How does the spiral tooth profile affect load sharing?

The spiral profile increases the number of teeth sharing load at any instant, which smooths torque transfer and reduces peak tooth stress compared with straight-cut designs.

What inspection points should be part of regular maintenance?

Regular checks should include gear mesh, backlash, pinion seating, lubricant condition and any sign of uneven tooth wear; address issues early to avoid secondary damage.

Is the included screw pin compatible with all listed models?

No, the M4*2.5*12 screw pin is not suitable for Wraith models. For Wraith installations, retain the original kit screws and verify thread engagement and clearance.
