Gearbox Grease
 

Just bought a G&G GR16 (not from 007airsoft), and read a couple guides about V2 gearbox maintenance. One guide suggested replacing the lube before using it for the first time. The other guide recommends using white lithium grease and silicon gel lubricant.

I have white lithium grease, but it is plant based versus petroleum based.

Amazon.com: Lubrimatic Green Biobased White Lithium Grease, 8-oz tube (10307): Automotive

Should I use it or look for some petroleum based lithium grease?

Thanks.

I was under the impression that you never want to use any petroleum based anything due to plastic and rubber degredation.

Can someone correct me if I'm wrong?

I heard the same thing. If it's flammable or contains petroleum, over time it will eat away rubber and plastic.

I don't think the grease is for plastic parts.

As I understand it the problem is with leeching.

The gearbox and gears might be metal, but there are a lot of other parts which interact with the gearbox that don't like contact with oil or petrol based chemicals.

You may run into problems even if there isn't visible direct contact.

Yeah, after looking at those guides you definitely don't want to use anything petroleum based.

If the white lithium you have is veg (cellulose) based it is probably just what you need.
Still though, apply it only to your gears, not the piston.

Actually.... I had someone tell me to not use White Lithium and instead use FinishLine Teflon grease. Apparently it's a lot better, more durable and overall just better than White Lithium. Also, apparently a tube will last you forever unless you're a gundoc or work on bikes a lot and even then it should last you a while.

How does Tamiya's boron nitride grease compare to their moly grease? My local hobby shop only carries the former.

After looking at the guide again, the only points that receive lithium grease are the gear axles and bushings. Everything else receives silicon gel.

Yes, white lithium grease is okay for gears and metal bushings but over time, it can get gummy and sticky. Unless you are going to clean and relube once or twice a year, I don't recommend it.

Remember, it's use is for metal on metal contact. It does contain petroleum so keep clear of your cylinder and use silicon grease in there as petroleum will kill your orings.

A good silicone will have enough film strength to protect your metal gears from undue wear.
When using 2 different lubricants in the same area, you have to make sure that they are compatible or undesirable things can happen. I would suggest using only silicone. Both Moly and lithium are solid lubricants and are used as extreme pressure additives in industrial applications. Not necessary for airsoft gear boxes. Stick with a pure silicone lube.

Awesome responses.

I appreciate this thread!

Airsoft Research Syndicate Sticky G Silicon and Molybdenum. The only greases you'll ever need for airsoft.

What are you talking about? This stuff is the last and only grease you will ever need.
