This mount is designed to fit MLToys red labeled 775 motors to gearboxes that came with 550 motors. If you have a Power Wheels 7R Gearbox use the 775 to 7R Motor Mounts instead. If you have Kid Trax gearboxes with 19T pinions you do not need this kit as 775 motors bolt directly to them.

Your gearbox must have a flat surface large enough for the 775 motor to bolt to (42mm diameter). You will also need a pinion gear with a 5mm shaft hole and the same tooth count, pitch, and mod as your stock motor had. Here is the 5mm pinions 32 pitch .8mod that we offer: https://www.mltoys.com/product-p/775-pinion.htm

Kit comes with 2 mounts and 4 mounting screws that go from the mounts to the motors.
