Alright, in this case we've got a magazine, a Tower Hover Speedmark magazine. Okay, I'm going to tear a little piece off with a foreigner. I think this has a little strip of the magazine. This piece of paper between the pinion gear, which is a little one, spur gear, which is a big one. And push the motor in. Pretty hard to bend the paper. Then tighten down both screws. Start with the bottom one and keep fresh on it, because it might try to rotate the motor when you put it. Okay, then spin the pinion gear, and you should be good. Another way you can do this is to run the motor and adjust this as you're running the motor and listen. If it's making a real loud grinding sound, it's too tight. If it's making a high pitch sound, that's too loose. I don't like that because you can screw up your spur gear. Okay, then you have a reassemble transmission. Make sure you got the piece of tape on. Alright, transmission is off the car. We'll take your out drive. Put it on, make sure there's a flat spot on the differential out drive. Make sure you line up your Allen screws with the flat spots. Or else it's going to get loose and come off. Okay, then tighten down the Allen screws. Make sure it's pretty tight, but not too tight. You can use lock tight on this if you want. I put mine on and off pretty often. So I don't like to tighten them down with lock tight. Okay, man, the other one. Nice! Alright, make sure these spin pretty freely. And if they do, you are a good go. Now you'll want to put the transmission back in the car. Put the out drives in first. That makes life a lot easier. Sure. Sometimes you have to push this thing in pretty quickly. There it goes. Alright, now make sure both of your out drives are still attached. Then put in that long screw with the threads at the top. In. Okay, then. Okay, now you should have this. Make sure the tires roll pretty freely. If they do, that means you did a good job. Alright, go on and put the screws back in the bottom of your transmission down here. Make sure you put the right screws in there, I hope. Alright, now your transmission should be held on there pretty sturdy. Okay, take your gear cover, put it back on, screw there at the bottom, screw at the top. Screws here somewhere else. And make sure you came out with no more pieces than you put in. See, I just replaced all the differential gears, and that's all I have here.
