Technical spur adapter for Axial SMT10 and SCX10 II platforms

The MJ1557T assembly provides a CNC-friendly aluminium adapter mated to a 57T hardened steel spur, intended for scale RC drivetrains and compatible with the Axial platforms referenced in the listing. The adapter isolates the mechanical mounting from the gear face so the steel spur takes torque loading while the aluminium carrier ensures concentric alignment to the gearbox output.

Engineered as a drop-in aftermarket upgrade, the kit concentrates on precision fit, repeatable fastener clamping and reduced play at the spur interface. Proper install maintains consistent mesh geometry and reduces eccentricity that can transmit vibration into the driveline.

Packing includes

  • 3X6 Stainless Steel Button Head Screw - 3pcs
  • 4MM Stainless Steel Lock Nut - 1pcs
  • Pelrin Collars - 1pcs
  • Steel Posts - 1pcs

Compatible Models

  • SSCX271557T

Select this component when you require a precision aluminium adapter with a hardened 57T steel spur for Axial SMT10 and SCX10 II variants; confirm dimensional match before installation and verify concentricity after fitting.

What tolerances should I verify during install?

Check axial runout at the gearbox output, measure radial concentricity of the adapter, and ensure fastener torque is applied evenly to preserve alignment.

Can the steel spur be heat treated for higher loads?

The supplied steel spur is manufactured for standard drivetrain loads; any further heat treatment should be done at a qualified facility and validated for tooth geometry and fit.

Are the Pelrin collars lubricated or pre-fitted?

Collars are supplied as separate components to allow precise positioning; apply light compatible lubricant where sliding surfaces require it but avoid contaminating fastener threads.

What inspection steps are recommended after first run?

Recheck fastener torque, inspect spur tooth contact pattern, verify collar seating and confirm there is no loosening or fretting at the adapter-to-gear interface.

Is any modification required for different pinion sizes?

Pinion changes affect mesh and clearance; re-establish correct mesh and motor clearance after any pinion swap, and inspect for interference with the adapter assembly.
