GPM Racing High Carbon Steel Motor Gear 15T - 2pcs Set for Axial 1/6 SCX6 Jeep JLU Wrangler 4x4 Rock Crawler RTR (SCX6015TS)

Precision 15T motor pinion

This aftermarket 15-tooth motor pinion is specified for AXIAL SCX6 applications and sized for motors that match the stated shaft and pitch dimensions. The high carbon steel construction enhances wear resistance versus common stock alloys and serves to transmit torque from the motor shaft into the drivetrain gearbox with consistent engagement.

Core dimensions include a 5mm centre hole and a 1mm tooth pitch; always verify these against your motor and existing pinion prior to installation. Installation guidance: set proper gear mesh with the spur gear, secure the pinion to the motor shaft using the supplied 4*4 screw shaft, and rotate the drivetrain by hand to confirm smooth clearance before applying power.

Packing includes

• Pinion Gear – 1pcs
• 4*4 Screw Shaft – 1pcs

What inspection points should builders check after fitting?

Verify concentricity of the pinion on the motor shaft, confirm even tooth contact across the spur, and ensure the fixing screw is correctly seated without introducing runout.

How does material choice affect service life?

High carbon steel provides higher fatigue and wear resistance compared with many soft alloy pinions, but correct pitch matching and mesh are critical to realise that benefit.

Any fitting notes for high performance setups?

For high performance motors, recheck mesh after initial runs and inspect both pinion and spur regularly to prevent progressive damage to gearbox components. Write Product Review Please sign in your account before you can write any review. Sign In Close
