The FTX 8953 Ravine Gear Pinions are designed for RC car enthusiasts, offering a direct replacement for worn or damaged pinion gears to restore optimal performance to your FTX Ravine model. While they provide precise gearing with an 8T configuration and a 2.3mm shaft, users should ensure compatibility with their specific RC car model before purchase, as they are primarily intended for the FTX Ravine.

These FTX 8953 gear pinions are specifically designed for the FTX Ravine RC car model. They feature a 2.3mm shaft, so they will fit motors with that shaft size.
Signs include unusual grinding noises, skipping gears, reduced acceleration, or visible wear/damage on the teeth of the current pinion gear.
'8T' refers to the number of teeth on the pinion gear, which is 8 in this case. This tooth count affects the gear ratio, influencing the balance between acceleration and top speed.
Typically, you'll need to remove the old pinion by loosening a set screw, slide the new one onto the motor shaft, secure it, and then adjust the gear mesh with the spur gear.
Gear mesh adjustment is a fundamental RC maintenance task. It usually involves sliding the motor slightly until the pinion and spur gears have minimal play (about the thickness of a piece of paper) without binding.
This product includes two pinion gears. The set screw or mechanism to attach the pinion to the motor shaft is typically part of the motor itself or requires specific tools not included with the pinion gear.
While they might fit if the motor shaft is 2.3mm, they are optimized and intended for the FTX Ravine. Compatibility with other models should be verified by checking the specific requirements of that model.
Verify that your motor shaft diameter is exactly 2.3mm. This pinion is designed specifically for 2.3mm shafts.
Check and adjust the gear mesh between the pinion and spur gear. Ensure there is minimal play without binding. Clean both gears to remove debris.
Confirm the pinion gear is securely fastened to the motor shaft and that the gear mesh is correctly set. Ensure the 8T configuration is appropriate for your desired performance.
Ensure proper gear mesh and keep gears clean. Avoid running the RC car with excessive dirt or debris caught between the gears.
