The console CANNOT be an V3 as V3 don't have that motor. It's either GH-004 or GH-005. (V1 or V2 on buccaneer's language.)
The position for the parallax gear (white cog) is stored on the EEPROM.
After editing the eeprom dump, fix the checksum at offset 18B. If the checksum is wrong I believe it will assume the Mechacon's ROM default (center). Flash it back and be happy.

To not waste your time trying to adjust/fix an optical pickup that has a dead DVD laser emitter, do this test:
Power on the console without disc or memorycard (no FCMB), go to the version screen and turn "Diagnosis" option on.
If the laser is still good enough to read DVD discs, the Mechacon will automatically adjust the parallax and the disc should read.
That position is actually the best adjust. So if it work you might want to take a picture and then attempt various numbers on the eeprom until it sets that position. I believe 0x80 (128) is the center.
