With the right setup, the gears will last. My stampede and scx10.2 both had the same spur for years.
Greasing a gear in the open will attract dirt and will probably give opposite results thdn what your looking for, not to mention fling it everywhere!
I agree! I've edited my original post to make it clearer, the gears in question are in the stock gear housing, so almost no dirt gets inside. When I did the brushless conversion to my 144001 (the vehicle in question) and I opened up the gear housing, there was very minimal dirt, and that was after about 1.5 years of use!
It would become a grinding paste, I agree, but would you say anything different after knowing this info? I'm guessing the gears would still fling the grease everywhere, housing or not?

Grease and dirt don't play well together.
See above (the post edit and what I wrote in reply to Chubaka).
I don't use grease on my metal spur/pinion setups. Just graphite. The only place I use grease is on internal gears, protected by a housing.
See above. Thanks Kevin, the gears are in a housing. I've heard that white graphite grease or whatever can be bad for your health, some guy on RCT swore that he'd never use it, said his dad or grandpa has some issues with it, possibly health related I think?
For years have used the tiniest dab of Tamiya Ceramic Grease on my pinion/spur. Steel or Aluminum to Nylon or Kevlar interface. This primarily for an on-road and drag racing environment. I would hesitate to recommend it for an off-road environment. This is for 48P gears.
Same for 32P on steel to nylon interface. In addition, on 32P I polish the [steel] pinion as the brand I buy tend to be a bit rough. Promotes longer spur gear life.
See above, the gears are in a housing that keeps 95% of the dirt and grime out. I'm probably a light basher at heart, but I run on-road a fair bit, not comp, just ripping around. I'll also go on gravel when it's not super dusty, and a little hardpack moist dirt here and there. The gears in my buggy are 0.7 mod, a pretty uncommon pitch.
Nylon is self lubricating, so I never use grease on my plastic gears.
Interesting! Why is that so, is it because they are oil based plastics or something? But that's for your Tamiyas, right? My buggy has a metal pinion, plastic spur setup. Not sure if the stock, plastic spur I'm using is nylon. Are nylon spurs common in budget friendly cars?
Same. The applied grease will be gone on the first run anyway.
And WHEN it attracts dirt, it becomes like a grinding paste, prematurely wearing down the thing you want to protect in the first place.
See above, what I wrote to Chubaka. Gotcha, thanks, I was wondering if the grease would stay on or not, apparently not! I'm familiar with the "grinding paste" effect caused by grease, lube, or oil mixed with mud, dirt, or sand. I work on my bike, and am into Mountain Bikes, so I have experience with that. (Kinda, I try to not create a grinding paste anywhere on my rigs)
I don't grease. I just pop the motor module and blow it out every now and then with some air, and I can actually HEAR the difference when it runs.
Thanks for the feedback! On my buggy, to spray out the main tranny, you have to at least unscrew the rear part of the top deck, and if you only do the rear, bend the top deck a little, slide the top tranny cover out, then blow it off. I'm not sure if it's worth the effort, as last time I checked it during my brushless conversion, the inside of the gear housing was pretty clean, after 1.5 years of light-ish use! Now that I think about it, it's not that hard to peek inside the tranny, so I might blow/clean it out, say, every 6 months. Just for good measure, and so I can have something to wrench on!
No grease. Even if I would get the hardened steel spur gear for my eBuggy... no grease would be used.
The only time I greased a spur, and pinion gear was when the instruction manual said to do it. '83 Frog...yes. '85 Optima... sort of, kind of did (on the "counter gear"/gear behind spur gear). After those two RCs... no grease.
What I thought was weird was the fact the 2016 Optima "re-re" states to grease the ends of the dogbones as well.
Ok, thanks HeavyBag!
Greasing the ends of dogbones, what the heck? You mean the end that goes into the diff outdrive cup, or the axle stub? I've never greased any dogbones or CVDs (ESPECIALLY not CVDs, #grindingpaste!), I'll wipe off and clean the dogbones, CVDs, diff outdrive cups, and axle stubs (for the dogbones), and relube with some "dry" chain lube, for bikes (since we also ride).
I'll do this every month to 2 months, mostly. Keeps those parts from getting worn too fast, and the dry lube (I also wipe off the excess) attracts minimal crap (kinda like what you want when dating someone...you don't wanna attract "crappy" people
).
No grease on spur/pinion no matter the materials.
Thanks man, does that hold true even when the gears are in an enclosed housing?
I personally don’t grease my pinion and spur because I have a truck that’s mostly off-road so I don’t want sand in my gears with the grease
Please see above, what I said to Chubaka and the edited post. Thank you for your input!
I agree with all the above. No grease on the pinon/spur gear set up. I only use grease on internal gears bud. That's it. If your mesh is good you should never have any issues
Yup, internal gears (ie. in a housing). Mesh is basically spot on, it's preset. My takeaway from y'all is to not grease gears, and only consider greasing gears when they're in a housing, and only in special conditions.
