Team Durango: Gear Diff Oil

[Stu Dixon]

Help needed on what oil to run (indoors @ bury) in a Dex210 gear diff ?
product code would help too

[Si Coe]

Most of our 210 runners still use the ball diff, but I run 3000wt in my 210. Not for any real tuning reason - its what I had from my old nitro but it seems to work well enough.

If It helps, most of ours are using the gear diff. (Indoor, high grip carpet).
Usually around the range of 2-5000wt. I think a couple have experimented with up to the 7-10000 sort of level, one guy is running moly grease, with quite some success.

The problem with geared diffs in general in any car is if it rains they're not very good at all. They're only Any good on
The dry. Ball diffs are a better all rounder

[Si Coe]

Except the 210's ball diff is the stupidest design ever and fails with boring regularity - just as Chris about his!
The gear diff isn't technically as good, but at least it actually works.....

[Gavin Collingwood]

Yep totally agree si, you need a degree in engineering to get that diff to work... Stupid design. Don't know why companies persist with the circlip/spring washer designed diffs I.e Durango, schumacher. The best diffs are the same screw spring and washer design that have been used for years I.e A.E, losi, kyosho ect... They're proven and are reliable, why change the design when the latter team have all those years of success with it?
And that's why I don't like those two cars especially.

What like my ball diff in my 210 that I rebuilt with ceramic diff and thrust balls about a year ago , clean every six months , and still works like a dream

Admittedly it is a bit fiddley fitting em
But otherwise no problems
Each to his own really at our level of racing
I do want a gear diff but its not essential

[Gavin Collingwood]

Exactly johnny, how much of that diff is stock....? Half of it isn't.

[mattr]

I really don't get the hate for c/e clips on here.
They are a well understood, standard design with masses (millions) of applications in production. Yet a few geeks, nerds and rc racers don't seem to be able to get the hang of them.
I only use a gear diff as I prefer it. The ball diff went together first time, took 20 mins to set up/bed in then ran for a couple of months with out being touched and is now in a mattress spares box (ready to run when he wants it).

Most of you rely on c/e clips every day. Wouldn't thing you could find many mechanical consumer goods with out a few in....

[Gavin Collingwood]

Yes I agree they work but they aren't as simple as the tried and tested screw spring and nut diff. To me it just seems like a load of extra parts and potential complication that's not needed. Just my opinion not going geeky just from racing experience that they're not as simple or reliable

[Gavin Collingwood]

Sorry for hijacking this thread by the way that is all :-)

[Stu Dixon]

Funny how it all kicks off over a diff !!
Anyway thanks for the advise...
The reason I got the gear diff was to minimise the amount of maintenance required and it looks a little easier to build and maintain (when required) than the ball diff.
I have read on hear that people have used shock oil in them ?? is that a possibility ?

[Si Coe]

Diff oil is basically the same stuff as shock oil, just much thicker. Shock oil would act as a lube but have no limited slip effect at all as its so thin - its not much different to no all at all.
