How to Choose the Right Gear or Gearbox

  1. Match Voltage: Use the same voltage printed on the toy (6V or 12V). Mixing systems can overheat motors and controllers.
  2. Check Shaft & Hub: Confirm wheel shaft diameter (e.g., 10 mm or 12 mm) and the hub’s groove/spline pattern for a snug fit.
  3. RPM & Use-Case: Lower RPM = quieter, more torque for inclines; higher RPM = more speed but higher current draw.
  4. Orientation & Mounting: Many jeeps need Left and Right gearboxes—match screw holes and orientation to the original.
  5. Material Choice: Nylon/plastic gears run quieter; metal pinions improve durability for heavier kids or outdoor use.

Best Picks by Use-Case

  • Quiet city rides: Nylon gears + mid-RPM gearboxes reduce grinding and deliver smooth starts on paved floors.
  • Inclines & parks: 12V gearboxes with stronger torque (mid-high RPM) help on ramps and grass.
  • Dual-drive jeeps: Replace Left + Right together for even wear and straight tracking.
  • Budget repair: If only the teeth are worn, swap the matching spur/pinion gear instead of the full box.
  • Heavy-duty: Prefer reinforced housings and metal pinions for frequent outdoor play.

Safety & Care Tips

  • Disconnect the battery before installation; keep small parts away from children.
  • After fitting, run the wheels elevated for 1–2 minutes to seat the gears.
  • Avoid continuous full-throttle on steep inclines; allow cool-down breaks.
  • Use a light silicone grease on exposed gears—avoid heavy grease that attracts dust.

FAQs

How do I confirm a gearbox will fit?
Check the toy’s voltage (6V/12V), shaft diameter (10–12 mm), and whether you need Left or Right orientation. Match screw holes and the groove/spline pattern with your old part. When in doubt, share photos and measurements with us.
Should I choose 6V or 12V?
Always match your toy’s label. 6V is slower and toddler-friendly; 12V offers more torque and speed for bigger cars/jeeps. Changing voltage without matching battery/controller/motor can cause overheating and damage.
What RPM is right for me?
Lower RPM provides smoother starts and better torque; higher RPM increases speed but may draw more current. For inclines or heavier kids, pick mid-to-high torque ranges (paired appropriately with motor and wheel size).
Do I need to replace both left and right gearboxes?
Recommended for dual-drive jeeps. Mixing an old worn unit with a new one can cause uneven pulling and faster wear. Replacing in pairs restores straight tracking and consistent speed.
Can I replace only the worn gear?
Yes—if the tooth count, module, and hub match. Swapping just the spur/pinion gear is cost-effective. If the housing or bearings are damaged, a complete gearbox is smarter.
Why is there grinding noise after install?
Common causes: misalignment, debris, or mismatched tooth profiles. Re-seat the gearbox, confirm wheel hub fit, and bed the gears with a short elevated run. Use light silicone grease only.
How long does delivery take?
Orders usually dispatch in 24–48 hours with pan-India coverage. Transit time varies by pincode and courier lane. Tracking is shared by email/SMS after dispatch.
What is your return policy?
We offer a 7-day replacement for manufacturing defects. Keep packaging and share a short issue video; our team will guide troubleshooting and replacement.
