Re: Working on a 9114B HP-IL Disk Drive Message #4 Posted by Diego Diaz on 18 Sept 2009, 1:06 p.m., in response to message #1 by Gerry Schultz
Hi there,
I think these pics may be of some help.
The "metal tag" you found rattling inside your unit is more likely the top head cover... (red circle -also missing- in the image) which is supposed to be covering, and magnetic shielding, the upper head circuitry. Your 9114B can live without that... ;-)
The eject mechanism is commanded by the gears and spring inside the green cirle. May be just a bit (use very little please) lubricating grease (not oil!) will help smoothening the ejection.
If you plan to leave your 9114 unit unused for long periods of time, it's highly advisable to put a dummy disk like the one in the picture below. to protect the heads. A cleaning disk can also be used (and are easier to find). Do not leave a real disk inside the unit as the magnetic coating may end up tearing from the disk substrate damaging the heads (as Peter has pointed out above)
Regarding the battery, although the original part (Panasonic LCR-226P) is no longer in production (AFAIK), you can easily find a matching replacement (PM631). Terminals are not in the same position but this can be worked out.
Best wishes.
Diego.
