So the time has come. The Kid Trax bronco looks cool, but the 12v conversion leabes a little to be desired. Sure, cruising around in the driveway it goes good enough, but out in the yard it just doesnt have the torque to truly propel around a 4y/o. Enter MLToys' Level 3, 18v conversion:
Normally this kit would come with a second gearbox, but since we already had the 2wd conversion they omitted those parts. Anyways, here we go!
The kit comes with larger 550 motors, so the geart boxes need to come out so we can swap them in
The new motors with their new pinion gears. Of note is the pinion depth is not set 'from the factory', you need to adjust the gear on the motor shaft to get proper engagement of the gearbox. If you dont, you will definitely strip the gears out!
One done, one to go. Yes its that simple.
New motor installed on the gearbox! Note the new motors come with Wagos which make reconnecting them to the Bronco's harness super easy
...and back together we go!
Since the conversion to 18v means we now have 2 batteries, i made a new battery hold-down so they cant go anywhere:
From there all thats left to do is to reconnect the wires for the motors and the batteries, same way it came apart.
The most important thing to do though, is to break in the motors:
ML Toys recommends running them for 15 minutes with no load to seat the brushes. I ended up running it for about 20 which is fine as well, the important part is just to run it with the tires in the air so theres no real load on them.
The end result? This thing is a beast now! It zips around the yard without a care in the world, and the battery life has improved as well! This is the way it should have always run. Here's hoping it holds up to the abuse....
