How To Repair Kids Car Gearbox / How To Change Kids Car Motor 

It might have made sense to clean it and re-apply grease, before it was closed up. There might be sand mixed with the grease, and it could make the gears wear.

Hello brother, my son's car is very slow, please guide me

Thank you sir🎉

Hi, need help on this

Tank you friends ❤️

can i replace a 390 gearbox with a 550?

Gear kitne rupaye ka hai

Can we chnge the 6 volt motor to 12 volt and will it increases the speed

If 2 motors are exactly same size and same 12000 RPM but one is 12V and another is 24V, what component is making the power output difference? The number of teeths from the motor gear? From car specification, the 12V model car have 12V 35W motor and the same car but the 24V model have 24W 200W motor. But the physics say that you can't fit 6 times more power inside the same case just because of double voltage. So in reality a 24V 200W motor which is using a 24V 7Ah battery can't be 6 times more powerful than a 12V 35W which is using a 12V 14Ah battery. So all the power trick is done by the gearbox. And the final torque of 24V motor can be max. 2 times bigger than the 12V motor.

What motor is used ? It is normal rs 550 / rs 775 or gear motors
