Step 1: Materials and Tools
1 - Futaba S3001 servo
- #1 Phillips screwdriver
- Dremal with a cutoff wheel
- Needle nose pliers
Step 2: Disassemble
1) Use the screwdriver to remove the four screws holding the servo casing together.
2) Gently separate the two halves of the case being careful not to lose any of the pieces.
Step 3: Modify the Servo(disengaging the Potentiometer)
Step 4: Modify the Servo(removing the Mechanical Stop)
- To begin, remove the screw holding the control horn on and pull the control horn off the out put shaft.
- Now that the control horn is removed, slide the output gear out of the top of the case by pushing on the shaft until it pops out.
- On the shaft you well notice there is a bit that protrudes from the shaft, if you look on the inside of the case where the gear and shaft were there are two bits that stick out and catch the bit that is protruding from the shaft, this is the mechanical stop.
- Take the Dremal with the cutoff wheel and carefully cut the bit that is protruding from the shaft away, being careful not to damage the gear itself.
- Put the gear back into the top of the case and check that it rotates all the way around without binding.
- If it doesn't bind carefully reassemble the servo, taking care to get the gears and shafts lined up properly and your done. If it does bind up still, you well need to remove more of the protruding bit and try again.
