Locking the read diff on a TT-01 for Drifting?

[AndyjcClod]

Hi All

I stuck some drift tyres on my TT-01 and to be honest it drifts quite well, I have been told if I lock the rear diff it drifts even better.

Can anyone explain to me what I need to do to lock the rear diff on a TT-01 so it drifts better?

I have been told blutack is the best way as this means you can remove it if you want to go back to racing instead of drifting at a later date. I have also been told glue gun is best for a permi fix.

I am unsure where I need to stick the blu-tack.

Take the rear diff apart. Stuff it full of cotton balls; they're easy to remove later. Reassemble. Drift.

Second the cotton balls or something similar. Don't recommend blu-tac, that was an old-skool way of doing it, but it eventually breaks down and gets more and more viscous, turning into a sticky black-blue mixture which is really hard to clean! Glue gun is another idea, although if you get too much in the diff casing and the assembly doesn't go back together neatly and square then you're in for a world of pain scraping it all out again...

How much is a rear spool diff online?

Hello Andy . There are two ways to do this . The first one is with blue Tac/ cotton ball / glue gun as you say . You take diff apart and basically stuff it with the blue tac ect so the gears can't turn . To my mind that's a bodgers way to do it .

The Second and to me best and simple way is to do this . Take the diff apart . Degrease and clean it . Then remove one of the 3 bevel gears from the y shaped yoke . Place that removed gear between the two remaining gears so they can not rotate . Reassemble the diff and its job done .

This is exactly the same way I locked my front diff on a CC-01 . It works and is 100% reversible to standard at any point .

Badhorie diff locking grease will do the job.

I just jammed a couple of small screws in mine and has been fine for a couple of years of bashing. Using a 9 turn brushless and 2s lipo and never had an issue. No idea what state it's in on the inside though 😮 I guess once it is locked there is little movement so I don't expect there to be much wear. Just make sure whatever you do it nice and tight with no play. However any of the previous suggestions will work moving one of the bevel gears sounds like the easiest option.

not only is it the easiest option its the strongest one . Your not modifying the diff parts at all and by using the original bevel gears its as strong as the original .

Its how the CC-01 scaler guys have locked their diff's for years BTW

Doesn't that introduce some vibration at higher speeds, since the diff is out of balance now? On a CC01 you're likely driving some relatively slow speeds, but with a drifter the wheels are intentionally spinning fast. Have you tried this for drifting?

Not tried it for drifting - not my thing , but as it works perfectly on the CC-01 even with a sport tuned fitted I don't see it causing any vibration issues . When drifting your not going that fast anyways are you as the whole point is to get the tyres to lose traction ? Or am I missing something ?

I guess you could actually fit 3 spare additional bevel gears if it actually does unbalance the diff

There's always the option of using the plastic parts included in the CC-01 kits specifically for locking the CC-01 diff, but that would involve spending some money. This is the lightest option, as it removes the spider and the 3 small metal bevel gears. I would look at what a proper spool would cost. As the TT-02 is now out, I would think that TT-01 hop ups will be quite cheap for a while.

Yup you could use the CC-01 G parts . Their under £10 on ebay . I used them on my rear CC-01 diff . As Martin says a proper spool would be the ultimate hop up for a drift TT-01 . . All depends what you want to spend .

The bevel gear method is a free fix that works though.

Yeah Racing do a bling alloy conversion for the TT-01 to make it a solid axel set up but its only doing the same job once fitted and you would have to import the parts I think

I use the bevel gear method on my TT01 drifter. I found that the unbalanced diff caused noticeable vibration when I spun up the wheels to break traction, so (since I didn't have abundant spare bevel gears lying around) I balanced it using a couple of small steel nuts and small pieces of blutac in the spaces not occupied by bevel gears.

On my TL01 I used the hot glue method. Lightly greasing the inside of the diff housing before gluing makes for quick and clean removal of the glue if you want to return to normal running. It is also less likely to go out of balance.

Well you learn something everyday . I didn't even consider the vibration effect . Seems it matters far more on a TT-01 after all

Thanks guys some interesting reading there! I am now thinking of locking my CC-01 as well lol
