What type of oil do you guys recommend for a nitro buggy's gearbox? High viscosity, low viscosity? Naming a few brand names would be cool too. Thanks

have you tried diff fluid yet...

I had tried Silicone Lubricant but it doesnt help lubricate it, it simply removed dust. What is the differential fluid anyway? anything special?

Silicone GREASE works better on gearbox gears. As for inside the diff, I like using general purpose automotive grease. It is heavy and helps eliminate some wheel spin. When you are adding grease, pack the gears and the spaces around them. This helps to keep grease in contact and moving with the gears.

Silicone grease seems like a much better idea than anything I could think of, how long would you drive before you regreace the gears? once per a driving day?

no use silicon diff fluid, its thick o you can tune the diff to have an lsd effect, you use different fluid front mid and rear.

Pack the gearbox with grease and drive. I have a Nitro Hawk that has never had the gearbox apart for regreasing. That's almost 15 years now.

k, I’m sorry but I forgot to tell you that my gearbox is not enclosed unlike yours, and thick grease might fly off, wont it? Ill definitely try to acquire some gearbox lubricant/grease to see what stays on longer.

If you're talking about the spur gear/ clutch bell, normally nothing is used between them. Grease and oil would only attract dirt.

oooooooh, hmm, i thought that something had to be used between the spur gear and the clutch bell since it feels very rough when i try to rotate it. No? or should i shift the enine half a millimeter away?

If the gear mesh feels rough then it's more then likely to close to the spur gear and will strip the spur gear pretty quickly. Here's a quick way to set up gear mesh loosen the screws that hold the engine tight to the chassis. Then take a piece of note book paper and tear a small piece off the paper. Then take that piece of paper and place it in between the bell gear and the spur gear. Then push the engine up against the spur gear, but dont push to hard then tighten the screws up and then grab the paper and pull it out. That sets the gear mesh almost perfectly. It takes all but a minute to do this and it sets the gear mesh up all most perfectly.

AWRSOME METHOD! *high five*

Umm, if no grease/lubrication is used between the spur gear and the clutch bell then arent you slowly killing your tranny?

no. if you have a buggy you have NO tranny. Just diffs to fill with fluid.

umm, if 'tranny' is the 2 speed gearbox then i do have it... If you mean reverse tranny then I do not have it... so i dont have to lubricate the spur gear and the clutch bell, only keep it away from dust?

thats not a tranny its a 2 speed... your car if its a one eighth scale buggy... look, post this question in the bugg forum. youll see.

lmao borat!

in my revo i use automotive bearing grease. it is even recommended by traxxas.

ok, tranny or no tranny DO I EVER put put anything between the spur gear and the clutch bell????

No never.

ohh cool, thanks
