Removed the motor assemblies. Looks weird with nothing inside...
The RA assembly is on the left with sensor unit; the Dec assembly to the right.
Measured the exposed shaft on each drive. Removed the drive gears. Needed a 2mm hex for gears. There were 2 grubs on each brass gear.
Removed the support plate from each motor. Exchanged the entire motor, that is the motor, wiring harness, gearbox, etc. Really, I moved the mounting plates.
Completed the swap. Reinstalled the assemblies and buttoned up the mount. Fired it up. All's well. Did a simulated alignment. The RA and Dec drives sounded OK.
Readied for testing.
