Thanks.
sorry for being off topic....

i can't get hold of spec-r gear diff for my 416X at the moment cos it's out of stock. but my LHS just rec'd shipment of u-pro gear diff for photon. my question, will this fit 416X? sorry if it's been covered before. many thanks

when reopening the differential silicone comes off well without leaving a trace

instead for leaking near shafts we have to wait the new o-ring from Spec-R, at the IFMAR World Championship they provided the TRF Team with a new transparent o-ring

RC MARKET , if you run NT1 diff in the Tamiya 416, what pulley do you use ? the stock Xray 38 T ?

You'll never get rid of the leaking completely, just like shocks, they will eventually need rebuilding as well.

Sounds like the new O-ring will help, and perhaps a thin, round, very large O-ring closer to the outside, like a 1/8 gear diff might help a lot more than the cardboard gasket that is currently used.

I've just ordered my spec-r gear diff for my TRF416X, but i've been reading a lot about diff oils.
I just don't know were to find some of these diff oils and i even don't know what would be a thicker oil.
The higher the number or lower the number?
I know that tamiya has diff oils of 5000, 10000 and 30000 but wich one is a thicker oil?
Can someone help me out with this mather?

Kind regards

The higher the number the thicker the oil. The real headache come in though with all the different rating types, WT, cst. There is no real standard so you have to pay attention to which type someone is referring to. Hope this helps, some atleast.

How does a thicker oil (higher CST) react compaired to thinner oil? What is a good starting weight for 17.5? (1000 CST?)
