The Tam diff is pretty leak free, most of the issues result from stripped gears if the mesh is out, and the shims cone.

Have a look at these tips from Jilles, and also look on youtube for his video.

For the shim issue, I've just replaced the standard shims with 1x 0.3mm thick shim, and also kept the outer diameter to the same size as the pin, to stop the outer regions coning.

while building the 417x I noticed the hole on the bottom deck battery holder in the middle, with the trf etched on it, lines up with the top deck where the belt tensioner screws in, so to make the chassis stiffer could you not run a post there and screw the top and bottom deck together in the middle as well, do you think it would be better, I am thinking less flex for carpet, any toughts on this or will not work, or cause a difference

That would stiffen the chassis a bit more, although who knows what the resulting effect will be on the handling. I stiffened mine at the front with a shaft from the steering bridge. I only tried it for one session and was indifferent to the results, but I will try it again.

Hy!

Are the new X Orings supplied in the new X kit? Anybody tried it yet? are they a direct replacement for the standard blue o-Rings?

Greetings Rainer

no you get the regular clear o rings, you do not get the blue ones, but they are a direct fit

Posted on TamiyaUSA website for the X-Ring:
These Damper X-rings have X-shaped cross-sections and offer increased oil sealing effect compared to standard O-rings with circular cross-sections. Made from special silicone material, these X-rings also maintain their shape, and therefore their sealing ability, for a longer period of time. This makes them ideal for use with Aeration Dampers such as Item 42198 Buggy HL Aeration Damper Set and Item 54028 Buggy Aeration Oil Filled Damper Set. Item 42214 is designed for use with silicone damper oil while Item 42215 is for mineral based damper oil.

Yup, Lee Martin (TRF buggy driver) says the X-rings are only for buggy shocks.

I have never had a leaky TC TRF shock in all the years I've ran them.

Naaaaaaaaaahhhhhhh
Just saying that the X-type shock rings are nothing new
Spec-R uses them X-rings now to get the gear diff leakage free and it works
Tamiya is comming out with them for the shocks but some one else beat them to it
They do work great and hold there own longer then the normal O-rings from what i have noticed.
Now we have to wait till they bring them out for there own gear diff.
Mine VII diff isn't leaking but hey, they need to work on something new 2 get something great even better

regards Roy
