ERS 210 DHS, PAS, TAS Repair - Part 1 - Servo Removal

In part 1 of our 3 part series, Chris at the aiboclinic demonstrates the tools and techniques recommended for removing the pitch, pan and tilt axis servos from a Sony aibo ERS-210. In part 2, we will demonstrate potentiometer cleaning to cure jitters as well as full clutch replacement. In part 3, we will demonstrate the re-assembly and testing of the head block.

This really helped me thanks.

I've taken apart a few of these motors and here are my tips:
- Dull an X-acto blade to create a precision pry for the three black plastic cap tabs at the top of each motor.
- To remove solder from the flex connectors, I use my Hakko 301 handheld solder pump. The kapton flex material is very delicate.
- To remove the white potentiometer wiper assembly from the shaft without damaging the thin metal fingers, I modified a GWS pinion gear puller to fit and provide clearance.
- To remove the black plastic cap (underneath the potentiometer) that might be superglued in, the chuck mentioned in this video is a great tip. I used a spare M2 chuck from a mini-lathe. But the real tip here is to add a bit of heat from a heat gun around the motor to break up and weaken the cyanoacrylate glue bond before pulling. Also, pull inside a clear plastic bag or else you might lose a flying tiny white gear when the bond suddenly breaks loose.
- Note that the pan motor and the pitch motor have different gears next to the motor pinions. Different torque\speeds for each of those motors.

Thank you for this video. I am new to aibo and got 2 aibo 210(1 supercore) and want to give them the best life. The supercore may need repairs cause he is considered “junk” by the seller. I hope to become good at repairs like you and others I’ve seen 🥲
