Revo Delrin 37T Spur Gear Replacement

The RE-029 Delrin spur is an aftermarket 37-tooth replacement intended for Traxxas Revo gearboxes. It is supplied to swap out worn or damaged plastic spurs and restore reliable meshing in the drivetrain.

Delrin (acetal) is commonly used for spur gears because it machines predictably and delivers consistent tooth engagement. Matching the Revo 37T tooth count keeps ratio changes out of the equation so attention stays on alignment and correct pinion spacing.

To install, access the gearbox, remove the old spur assembly, fit the RE-029 on the shaft or carrier, then set axial position and check mesh against the motor pinion. Use the vehicle shims or tweak pinion distance to ensure smooth, non-binding engagement.

Fitment Compatibility

  • Traxxas Revo

Will this swap affect handling or gearing?

No, the tooth count stays at 37 so gearing and handling characteristics remain as originally configured when fitted in the same position.

Do I need special tools to fit the RE-029?

Basic hand tools to open the gearbox and set shims are sufficient. Check the pinion for wear while the gearbox is open and replace if needed.

How often should I inspect a Delrin spur?

Inspect the spur after heavy runs or signs of rough meshing; regular checks help catch wear before it affects drivetrain components.
