Step 3: Poke Out the Insert

There is a black insert pressed into the output knob.  This normally turns the pot below, but we're going to take it out.

The easiest way to do this is to poke it out with a pin.  There are two holes in the white plastic piece that make this really easy.

Once the insert is removed, you can throw it away, but be careful not to get it confused with the black washer.  We still need that!
Thanks for the walk-thru, just bought a 4 pack on Amazon and will refer to your guide when the time for "continuous time" comes!
Well done! I just ordered some off Amazon(They are back in stock as groups of 4, 8 and 12!!).<br><br>I will look forward to ripping a few apart and following your guide ;D
<br><br>That is the easiest-to-modify servo I've ever seen. With some types it's quite a fiddle isolating the pot from the output gear. <br><br>You mention setting the controller to zero - Normally you'd set it to mid-range (1.5uS) and adjust for no movement so you have forward and reverse control of the motor. Does zero correspond to the mid-point on the controller you're using?<br><br>The other thing about servos is that some types are better than others for fine speed control. I've had one which gives 20 steps each side of zero ramping up to full speed. Others have reached full speed at 5 steps. Digital servos are better than analogue ones for this.<br>
Yeah, these things are great. They can be modded in like 30 seconds!<br><br>That's correct. When I say &quot;zero&quot;, I'm referring to the center of the range.
