Re: Repairing DISK ][ Drives

[sjensen@eis.calstate.edu (Steve Jensen)]

Some advice on your Disk II- If the problem is just that it's coming off
the cam towards the rear, just take the top off the case first.  If it's a
Franklin clone the 4 screws may be on the sides rather than the bottom as
on a Disk II.  You can see the flat grooved cam disk without removing
anything else and you can see the 2 rails that read/write head slides on.
Some times a very thick disk or a user bending the disk when inserting it
will cause the little thing that goes in the cam groove to be pushed out of
 the groove to the rear.  I lubricate the 2 rails with TriFlow, which leaves
teflon microballoons.  Don't lube with anything else.  I use a spray can of
squirt a little in an old spoon or something, then using a long q-tip or
sponge tip applicator, put some on the rails and move the cam back and forth
by hand a bit.  Don't spray anything into the drive though.  You may need
the drive realigned or have a bad stepper motor.  You might operate the
drive without the cover to see if it's getting out of the groove while in
operation rather than when a disk is inserted.  Remember, NEVER install or
disconnect any disk drive with the power on.  The felt pad on the pressure
arm is not supposed to rotate.  My friendly Mac dealer ordered me a dozen
felt pads for $3 each.  You can email me if you still have problems.  I can
align your drive if it needs it.
