To remove the scanner, you must first remove the belt, which can be slipped off. Next, unscrew the ground cable from the right (non-belt) side of the scanner. Mark where it connects to on the chassis and the scanner. Put the screw back into the scanner.
Next, unscrew the four screws on each corner that are holding the scanner to the chassis. Remove the round wire harness if it is there. Remove the rubber o-rings and the bolts, but leave the metal axles there.
+
+Now comes the hard part. Either you can unbolt the section of the chassis which has the motor on it, or you can squeeze it out. It's a real tight squeeze, but it it won't really damage the scanner unless you really try. Remove the 2 screws on the metal plate at each end, but DO NOT remove the metal plates until the scanner is all the way out. You'll have to be creative; twisting the scanner so that the axle and wire connecter+harness on the left end of the scanner can come through. This can be done by pulling out the right end first so it's at an angle, and slightly bending the metal bracket/chassis out to allow it to slide through.
+
+Once it's out, you don't need to unsolder all those wires. Remove the two plastic ends. DO NOT DAMAGE OR BEND THE TWO PINS. On the inside are 16 capacitor strips. There shouldn't be [ZincDendrites] on the inside, but if there are, soak it in denatured alcohol. The wire clips are fairly strong and well-placed so you shouldn't need to re-do those connections.
+
+Use a continuity tester or a multimeter set to ohms (should end up close to zero) to check the connection between the terminal on the left end (behind the plate you removed) and the pin it goes to on the vibrato board. Next, check the connection from the terminal on the right end to the ground screw.
+
+Spray the two pins with DeOxit or a similar electrical cleaner. Use a cloth or your fingers to clean any gummed grease (gunk) from the gears. Spray the gears with Lithium grease ("White" grease) and spray the bearings also. Turn them to let it coat the gears. Try not to get grease on the capacitor strips or the electrical connections.
+
+Next we move on to the brushes. In each end, there is a terminal, two springs, and two circular magnets on each spring with a brush going through each. Test the connection between the springs and the terminal. DO NOT spray anything on the brushes except electrical cleaner if you so desire.
+
+You will need to put the drum back on the left plastic end first, because of the clips. Carefully fit the pin through the hole into the chamber with the springs/magnets. Then, with a pair of needlenose pliers and small fingers, put the two magnets back on the pin. There is one spring that is mounted lower than the other; put this one on first. The pin should go through the hole in the middle of each magnet.
+
+The springs and their solder joints can become stiff or out of position, causing squeaking or bad connections. Once the magnets are on, heat each spring for 15-20 seconds with a soldering iron, being careful not to melt any plastic. Next, melt the solder at the end of each spring fully and let it re-set.
+
+Do the exact same things to the other end of the scanner, and put it back in. DON'T DAMAGE THE PINS. Bolt everything back in, MAKING SURE to put the rubber o-rings back so that they cushion the joint between the metal axles and the chassis. Remember, it'll be a tight squeeze to put it back in as well.

+I tried to make this as clear as possible; feel free to drop a note here if you want clarification on anything or have questions.
