Precision #45 Steel 20T Pinion for Axial Yeti 32 Pitch YT020TS by GPM  [YT020TS]

Engineered pinion for Yeti drivetrains

This single-piece #45 steel pinion is produced for Axial Yeti and Yeti XL 32-pitch gear systems and is supplied as a 1pc set. Machined to 32 pitch with a 20T tooth count, it is intended as a direct replacement or a tuning option for final drive ratio changes; the component carries part code YT020TS and is compatible with standard 32-pitch spur gears used on those chassis.

Installation and setup protocol: confirm 32-pitch compatibility before installation, set precise gear mesh and measure backlash after assembly, and conduct a controlled low-load run-in to confirm smooth gear engagement. Replacing a larger pinion with a 20T will increase motor rpm and reduce torque at the wheels, so select tooth count based on intended duty cycle and terrain.

Material specification and function: manufactured in #45 steel to provide improved wear resistance under repeated use and abrasive environments, this pinion serves as a durable motor-to-drivetrain interface while maintaining original spur gear geometry.
