There are trillions of tutorial like this, I know :-)

They where taking at school during lunch break with a Sony Mavica camera ( floppy disk )!

The recommended tools for this project: 
1 x safety glasses!! 
1 x soldering iron 
1 x desoldering pump 
1 x wire strippers 
1 x side cutter 
1 x scissors, knife, x-acto, etc 

You will need a set of screw driver to remove the four screws on the back of the servo.

I put a peace of tape so the gear box does not come appart when I remove the back cover.

Remove the back cover by removing four screws.

If you use a solder pump, it will be easy to desolder.

Be sure you have remove every solder before starting lifting. 

When you are sure, take a flat screw driver to lift it.

Solder long wire to the motor. 

Use the original servo wire. Remove the white wire.

After some thinking, I realise that you don't need to cut the tap for the one motor walker.
If you want to build the one motor walker, I suggest you try the to build the robot without cutting the tap.If you want to make a rolling robot by using servo motors for the locomotion then cut the tap.

To cut the tap please read carefully.

Warning!

I have already broken the entire gear by using a side cutter. I was sort of piss off!
I recommend you be carefull and use a hacksaw.

Take your time!

Put every thing back together and you have finish!
You can put some new grease it the gearbox if you want.
