Conuctivity of spray lube?

Dec 08, 2004 12 Replies

Sorry to clutter the forum with a real basic question, but I have an electronic display piece that needs maintenance. There are plastic gears that make the piece rotate; the rotation feature is running very rough and there is exposed wiring near the gears. If I spray some wd40 in there to see if the gears are running rough due to dryness, etc, will that affect the wiring? Does spray lube conduct current?


Thanks, but can that be sprayed? I can't reach into the mechanism, and I don't want to risk taking it apart...yet.

Get a straw or a coffee stirrer, put a bit of grease on it, and dab it on a gear. A little goes a long way.

Or is the mechanism sealed somehow? Is appearance important? Spraying would probably smear any plexiglass casing.

I doubt that conductivity will be a problem with any lubricant that is not specifically designed ot be conductive. But WD40 is a poor lube for plastic gears. I think white lithium grease would stay on the teeth and last lots longer.

I think they make spray lithium grease still. I have a can of it, somewhere.

somewhere.

first use a light solvent to clean the dirt out, beware of the solvent not to attack plastics then you might rince it using hot soapy water have it dried thoroughly next use some lubricant (machine oil,...)

only using cleaners just displaces the dirt, by which the dirt will cause probs later on

Are you guys forgetting that he doesn't want to take it apart? Cleaning the crud out is only effective if he can get the dirt *out* of the mechanism. I would use machine oil on plastic gears. Machine oil is used for spindles, motors, etc where there's no plastic parts. Lithium grease (white) is best for plastics.

Cheers, Mike

and

Correction: wouldn't use machine oil on gears.

Thanks for all the useful info, and after reading all the replies, I have decided to return the item (it was an ebay purchase). I will try again with another auction that lists the item as mint and/or perfect working condition.

Many of those parts *do* have smaller or larger holes in them that's how the dirt gets in in the first place.....
