Gear diffs
 

Could someone give a bit of an explanation to the gear diff/oil thing?

First confusion lying in the fact that everyone is saying diff oil, but the setup sheet from, I think the japans, says diff grease. So, is it grease or oil? Oil is viscous liquid. Grease is semisolid. They're 2 very different things and the words are in no way synonyms... I'm assuming it's actually grease because I doubt those diffs are sealed up well enough to hold oil. Yes?

The setup sheet posted a bit ago said 20000 in the front (but the kit comes with 2000 I believe judging by the parts list, so is 20000 a typo?), and 7000-10000 in the rear. Another typo meaning 700-1000? Or is the parts list I received from Durango a type and it really is 20000?

What does a lower number mean, thicker or thinner?

Where can these different weights be purchased since Durango apparently only carries one weight.

Thanks!

All the rallyX cars use oil - so theres many places to buy it. You can use grease or oil - yes they're sealed up. :thumbsup:

All the 1/8 kits use oil/fluid so can't see why these can't as they are sealed diffs

no typo look for 1/8th diff oils they go from 500 right up to 20000 i believe, and everything in between, higher number is thicker oil,diffs seal up nice and tight,

I've seen people run 100 000wt in centre diff of dirt oval kits

Have a read throught these two guides

The diffs are sealed well enough for oil, that's what you get in the kit.
The grease is for lubing the mating gears (Crown and pinion).

Thanks guys, had no idea. I haven't touched a 1/8 buggy in ages, and back then the diffs, at least the ones I had, didn't seal up at all. Hell, the gearbox itself barely sealed up, lol.

So what would be good starting points for front and rear? I'll be on grass/very loose dirt, medium size track, fairly rough. Should I just put 2000 in both and see how it goes?

Thanks again

Try 5000 front + 1000 rear

Where's the best place to get a decent selection of oils from?

Prob M-K-racing, he got loads diff oils as he stocks hell alot of rallycross stuff.
I'm going to get it from thier if needed but i already have these weights from doing rallycross myself.

anyone have a suggestion for diff oil weights for dirt tracks low to med grip with no astroturf or grass at all

Lighter oils for low grip.....heavier oils for high grip astro etc

Is there oil running out of the diffs??:confused:

That's what I fear most!:bored:

Any experiences about that?
