- This guide will show you how to replace capacitors in ACE HD floppy drives.+===== X68000 Floppy Drive Capacitor Replacement ===== 
 +The original capacitors in the X68000 floppy drives will, given enough time, dry up and cease to function properly.  This is not a problem unique to these drives, most electrolytic capacitors will similarly fail eventually.  This guide will show you how to replace capacitors in ACE HD floppy drives.
  
-Due to time and age the original capacitors tend to dry up and thus electronics which depend on stable and fluid power supply tend to work faulty or not work at all. Try my other tutorial on floppy drive repair before doing this.+Be warned that your problems may not lie in the capacitors.  Try my other tutorial on floppy drive repair before doing this.
  
-Only low profile capacitors are used in the drive so make sure that you buy the smallest you can get. If in doubt, take one sample to your local radio shack when purchasing. Soldering wick will come in handy in removing the old capacitors and cleaning solder from holes where capacitor legs used to be soldered. I used an 8W 12V micro soldering iron just to be on the safe side. When replacing capacitors be extremely careful in observing the polarity+Only low profile capacitors are used in these drives so make sure that you buy the smallest you can get.

- Disconnect the signal cables by pulling them in straight direction away from the socket. Use tweezers to gently disconnect the big brown signal cables and use extreme caution when disconnection the signal cable which goes to the step motor. Grab its wires tight at the base of the plastic so that they are not loose and gently jiggle the plug out of the socket. Unscrew the eight circled screws. Please note that by unscrewing the four screws from the rotating disk assembly allows better access to capacitors and makes replacing them a bit easier.+Disconnect the signal cables by pulling them in straight direction away from the socket.
