Looks like you might need to buy the entire diff assembly. Have you tried automotive gasket sealer?

You probably have to order the entire diff. You want to email Tamiya America, They are usually quick in answering.

I havenít tried automotive sealer, but Iíll give it a try. I donít want to buy an entire unit. I thought tamiya would use this gasket on other diffs. Iíll send them an email and let you guys know what they say.

Tamiya is notorious for packaging parts together in bundles. Buying individual parts is often impossible. Try buying body posts alone and you'll see what I mean.

I have no personal experience with neither of these diffs, but there is a nice review of the 3racing one from theRcracer (this guy is also member here)

Iíve used both diffs. The 3Racing one is lighter, the Tamiya one is much more reliable, itís still smooth. The 3Racing one did get notchy after a couple of months.. itís ok but didnít feel smooth like the Tamiya one.

Thanks for the feedback, I already ordered one from Tamiya.

The TT02S and TT02SR use the same arms as Tamiya TC chassis. They do not have an upper arm. The SR adds a few extra hop ups to the S.
Out of all those model variants which is the best for outdoor asphalt racing??

Default New tt-02 version coming out soon??

Hello. Is there gonna be a new version of the tt-02 coming out soon?? Reason I ask is because the tt-02sr version has already been discontinued just like most of the variants. It seems the stock and r version are the only ones left that you can buy new. Thanks

I have the 3Racing diff for the TT02. Not sure how beneficial this information is as I have just the one. After I assembled the diff, I left it sitting unused for a time. I noticed that even without use it was leaking oil. I took it back apart, cleaned all of the oil and grease off, and noticed that the gasket surface on the diff housing wasn't exactly smooth. I decided to lightly sand it with fine sandpaper. Just enough to smooth off any of the plastic flashing/burs. After doing so, the diff hasn't leaked yet! Your mileage may vary, but if you find yourself with a leaky diff, I suppose this could be a potential fix.

Cheers

A new top version of the TT-02 would be neat. I have an SR that I'm about to hack up for an experiment... If ever I find an on road track to frequent I'll probably need something that meets class specs again.
