GPM Racing Hardened Steel #45 Motor Gear 26T for Traxxas 1/7 Unlimited Desert Racer-85076-4 (UDR026TS)

UDR 26T precision motor gear

This 26-tooth motor gear is specified for the pinion location on TRAXXAS UNLIMITED DESERT RACER chassis with part number UDR026TS. Manufactured to resist wear, the hardened steel #45 construction delivers a service-life improvement over soft alloy replacements and is intended for hobbyists focusing on durable drivetrain upgrades and tuning corrections for motor-to-spur engagement on 4x4 vehicles.

Given the 26T pinion and the referenced 127T spur, installers must verify gear mesh and axial alignment before final assembly. Use the correct motor-mount hole to set backlash and ensure loads on the motor shaft and bearings remain within acceptable limits.

Contents: one Motor Gear and one 4x4 set screw provided as repair or hop-up hardware for the pinion area. This component is for RC model use and supports consistent drivetrain performance under typical hobby conditions.

What inspection steps are recommended after fitting?

After installation, verify axial runout, check set screw torque, and perform a slow spin to confirm even mesh across the tooth face.

Can this pinion handle high-torque setups?

Hardened steel #45 improves resistance to wear and deformation, but confirm motor torque and pinion diameter compatibility to avoid overloading the shaft or bearings.

Recommended maintenance routine?

Periodically remove debris, inspect tooth profiles for chipping, and recheck set screw tightness after high-stress runs to maintain reliable operation. Write Product Review Please sign in your account before you can write any review. Sign In Close
