Sounds like your just over filling it you only need to fill it up to just below the plastic T

Like JasonC says - if everything else is okay, you are probably using to much oil.

But it is normal for it to leak a little for the first couple of runs.

Regarding the shims, I can't say if it better, as I have only used the standard shims provided with the geardiff, and my diffs work great.

Hi there I have just bought the spec r diff for my X-ray T3. I was wondering what is the difference between the stock diff gaskets that come with the set and the green version 2 diff gaskets? What does it mean that they are matched with 0.2 mm internal shim?

Thanks

Default Sanding the gears ?

I have e question about (how much) sanding the gears from the Spec R diffs?

I build one for the 416, and one for the TB03, and only had a used 1000 sanding paper for polishing/sanding the gears.

I builded them up per instructions, and think that the gear mesh is to thigt.

With wich kind of sanding paper, or other stuff did you guys sanded/polished the gears, and how much?

BTW. i filled both with 1000 oil.

Greetings Blueman

I use 600 sanding paper.
The gears do need quite a lot of sanding to get the geardiff silky smooth. If you can feel the gears / the teeth when the geardiff is assembled and you turn it by hand, then it needs more sanding.

It is hard to explain (especially when english is not my first language), but when you turn the outdrives, it has to feel silky smooth. If you can feel the gear-teeth touching when you turn the outdrives, then it needs more sanding. It can take a couple of tries.

Thanks for your explanation. You only sand the rear of the gears right. and also what is the shims adjustment for?

Yes - Only the back of the gears. If you don't sand the back enough, they will sit too close and be too tight.
I can't answer you on the shims question. I just use the stock shims and my diffs work great.

Do you only sand the back of the outdrive gears or also the smaler "cross" geasrs? or both the same way?

Thx for the info!
