Installation & Usage Instructions

• Confirm compatibility with your model before installation, and verify mounting hole alignment with your chassis.
• Secure the gearbox with included screws; avoid over-tightening to prevent housing cracking.
• When installing the pinion gear, use the adjustable window to fine-tune gear mesh for smooth, jamming-free operation.
• Apply a small amount of model gear lubricant to the gears before first use to reduce noise and wear.
• Regularly check screw tightness and gear condition, and clean internal dust/debris periodically.
