Precision aluminium spur adapter assembly

This two piece upgrade consists of a CNC-friendly aluminium spur adapter mated to a hardened 32 pitch 66T steel spur, specified for Axial Racing Yeti platforms. The adapter provides a rigid mounting surface to maintain tooth engagement geometry while the steel 66T holds profile under repeated torque cycles, improving repeatable mesh and drivetrain predictability without modifying chassis datum points.

Mounting is performed at the gearbox output where the adapter replaces the stock spacer or plastic adaptor and the 66T fastens with existing hardware. Set mesh by rotating the drivetrain by hand, adjust stack height as required, torque fasteners to recommended values and use thread locker on metal screws where appropriate. Reinspect mesh after initial bedding in under light load.

Specifications

  • Item: Aluminium spur gear adapter and steel spur gear 32 pitch 66T set
  • Material: Aluminium adapter, steel spur gear
  • Model Number: YT1666T
  • Compatibility: Axial Racing Yeti

Spec this assembly when you need a dimensionally stable aluminium adaptor with a hardened 66T steel spur to reduce deformation and deliver consistent gear engagements under load.

What tolerance should I aim for when setting mesh?

Aim for minimal backlash with a light running clearance across the face of the teeth. Use feeler methods or paper tests to ensure uniform contact without binding.

Are there recommended torque values for the adapter screws?

Torque depends on screw size and material; use modest torque to seat the adapter without stripping threads and apply thread locker for steel fasteners to prevent loosening under vibration.

How does the steel spur affect long term wear?

Hardened steel resists tooth deformation and chipping better than softer materials, extending service life under higher torque cycles, though periodic inspection remains essential.

Can this adapter correct misalignment from other parts?

The adapter ensures consistent mounting datum for the spur but will not correct major misalignment elsewhere in the drivetrain. Address worn bearings, bent shafts or damaged housings before final mesh tuning.
