Freeing a sticky floppy drive
This one's quite easy as long as you are happy about taking
your Apricot apart. These instructions are for an Apricot PC.
You will need some three-in-one oil with dropper or similar
and a spare floppy disk.
Step by step:-
- Take case off (three screws in the back of the case,
the back falls off and the top cover can be lifted off).
- Remove the drive cables (one power and one ribbon cable each).
Watch the power cables - they're stubborn.
- Remove four screws that hold the drive cage down onto
the metal plate underneath. There are two vertial screws
on each side.
- Turn the drive cage over on it's top and
remove the offending drive by undoing the pair of screws
on each side. Watch out for the loose
floppy drive eject button and the loose spring behind it
(ie don't loose them).
- Remove the metal cover on the drive (one screw at back).
The mechanics that need attention are on the right
hand side of the drive.
- Insert the floppy and watch the mechanics near the back of
the drive. There are two bars that slide back and forth.
The lower one goes almost the full length of the drive
and is pushed by the eject button. The upper one
is shorter and is near the back. A small arm pivots
right at the back of the mechanics. At the front of the
arm, there is a small stud which is meant to flick
between notches in the top and bottom arms.
When the drive is sticking, it has to be persuaded.
- Use the oil sparingly and make sure it only goes on the
mechanics on the side of the drive.
Oil the sliding bars where they are fastened to the drive
cage (two round fasteners through a hole in each bar).
Oil the small pivoting arm. Oil it around it's edge at the
pivot end. Oil it on it's surface where you can see it
on the side of the drive. Put a very small amount of
oil around the stud.
- Insert and remove the floppy a number of times.
Move the stud manually at first to ensure you get the full
- Re-oil any of the parts which have since got dry because
the oil has moved out of sight to where it is needed.
Still use it very sparingly.
- Exercise the drive again a few times.
It should be starting to free up now. Don't expect it
to be perfect - this should come through normal use.
- Replace the drive cover (screw at back).
- Pop the drive eject button back in the facia and
insert the spring in the button.
- Hold the drive cage upright on it's front and lower the
drive into it. Tweak the LED with a screwdriver
if necessary to make sure it slots back into the entry
point in the facia. When in position, screw the drive into
- The rest should be easy - just a matter of reversing the

Thanks to Bill Appleton for the information:
- Dismantle the monitor case and remove the
- Un-bolt the tube from the frame and the mesh will also come
away with it. The mesh is seperate from the tube and is
only made of plastic.
Wash it out and dry with a hair dryer.
- Clean the face of the
tube with glass polish and re-assemble the electronics
done this to several Sirius screens and the differance is astounding.
There is no other way to do this. Bill"
