Dead HS 645 servo

I have a Lynx SES robotic arm robot arm that I have been using for about one year. Recently, the servo in the elbow joint, an HS 645, has stopped working. I moved the servo cable to a different position on the controller to make sure the SSC-32 controller wasn’t the problem. Still no operation.
My questions:

  1. is it normal for these servos to fail after about a year of use?
  2. does the servo have any “user serviceable” components? That is, if I take the servo apart are there things I can check for and try and repair the device?
    best regards,
    Joe

It’s not unusual to have a servo die, especially one that’s under a large load like the shoulder servo. There is a replacement gear set for the servo, but beyond that there are no user serviceable parts inside the servo.

Jim,
Thanks for the reply.
I will order a replacement and then take apart the dead one and see what I can learn.

Regards, Joe
