WD40 is primarily a degreasing solvent, NOT a lubricant. It has no place in projector lubrication. Spraying silicone lubricant , or spraying ANY lubricant, inside a projector is a bad idea.
I very rarely, if ever, have to lubricate my Eumig projectors. They seem to be 100% self lubricating. My Elmo GS1200'S are another matter. They seem to need periodic lubrication (about once a year in my case)to keep them running smoothly. I use Molybdenum grease for the shuttle cam and cam follower, a little lithium grease on the plastic gears, and a a couple of drops of thin instrument oil on the main shaft bronze bearings and solenoid linkages.

I'm with Paul on this ...
If the "lubricant" you are using is not specifically designed for projector's AND specifically for your specific model, DO NOT use it on your projector.
Another factor to point out ...
What lubricant you use on your projector will, to a greater or lesser degree, be transfered to your film prints.
Think about that.
If you would never use it on your film prints, then why should you, for a moment, think about using it on your projector?

I only speak from experience, I'm not saying WD40 is the answer
to everything, but I did have a Eumig projector that used to emit an ear splitting scream from it's motor after a time showing film.
I gave it a little squirt of WD when it was cold, on the "ball" pillar,
since then it has not uttered a squeak, and shows film as quietly as it should. WD is I think a lubricant, Pet. Ether & Methylated Spirit I would term as degreasers. Some folks were using this stuff as a film lube at one time, and it is greasy to the touch.

Maurice, I would suggest that anything that appertained to use has long gone, the chemicals that really cleaned, lubed or
"done what it said on the tin" are long gone, you now have through the EU, a legislation banning the chemicals that actually
done the job, hence the recent carry on with Dettol.That's why our
washing powders don't clean as well as they used to.My point
being, that the chemicals that did the job, are now banned, so
the weedkillers don't kill, the disinfectants don't work, and your whites
don't shine anymore, unless you have a boiler.
