In this tutorial, we learn how to install a new engine in an RC Nitro Truck. First, fix the engine fly wheel and then fix the clutch shoes. After this, fix the drive gear by making sure the bearings are fit into place. Next, put the drive gear on, then make sure there isn't any friction. Now fix the lock, then fix the clutch shoe spring. Make sure the spring is locked and fit into place. After this, tighten the screw to lock the drive gear, then you are ready to use this engine. Place it into your RC car by screwing it properly into place. When finished, drive your car and enjoy playing with it!
