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

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

Step 1: How to Modify a Servo Motor for Continuous Rotation ( One Motor Walker Robot )

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.

Step 2: How to Modify a Servo Motor for Continuous Rotation ( One Motor Walker Robot )

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

Step 3: How to Modify a Servo Motor for Continuous Rotation ( One Motor Walker Robot )

Remove the back cover by removing four screws.

Step 4: How to Modify a Servo Motor for Continuous Rotation ( One Motor Walker Robot )

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

Step 5: How to Modify a Servo Motor for Continuous Rotation ( One Motor Walker Robot )

Be sure you have remove every solder before starting lifting.

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

Step 6: How to Modify a Servo Motor for Continuous Rotation ( One Motor Walker Robot )

Solder long wire to the motor.

Use the original servo wire. Remove the white wire.

Step 7: How to Modify a Servo Motor for Continuous Rotation ( One Motor Walker Robot )

This is the inside of the gear box.

Step 8: How to Modify a Servo Motor for Continuous Rotation ( One Motor Walker Robot )

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.
