This is common problem with any machines that factory-grease or oil
gave up it's ghost. With cleaning fluids first, please, to wash out
those old lube and dirt collected during lifetime then relube it with
proper types that will not go bad. Strangely, these old grease
looked the same and low quality as in lamp turn-switches assemblies,
many vcrs, old tape players that I repaired. Brownish-amber colored
kind.

Lubes types:
WD40 and any 2 in 1 oils are N.G.
Lithium grease (used same way in vcr's) is great lube.

The mac floppy drives ejector/rail mechanicals and the die-cast base
of heads, spindle /w circuit board unit seperates after undoing few
E-clips and (screws?) also maybe needs to replace the worn eject
motor.
