I normally soak ball races, etc in petrol (best) or
paraffin (safer, but
not so good) to get the old lubricant out.
The main ingredient of WD-40, Stoddard solvent, is a form of paraffin
(kerosene).
I never run an 'unknown' motor or mechanical
device without checking the
lubrication and probably replacing it. I remember the comment in the BRPE
service manual 'running this punch for 10 seconds without lubrication
will ruin it' or words to that effect. Oil/grease are a lot cheaper than
mechancial parts!
The grease and oil on some of these punches/readers is creeping up on 40
years old. It just isn't any good anymore, even if it "looks OK".
Most fans, too.
