yeah the XC/CC01 uses the blue steering knuckle from the TA02, with 1510 & 1260 bearings ;)
Its the exact same molding but done in grey or black recycled for use on TA03 & FF01.
TA02's C-hub is different though... less castor than TA03's.

Dogbone length is same.

53172 is a true oldskool "universal" drive joint though, not a cardan CVD design.
Have been wondering if OTA-R31 'bones can fit too as they use a 1510 & 1050 bearing.
Haven't tried though; need a 1250 bearing or we could stackup a 1280 + 850 bushing ;)
That'll modernise the CVD if it did work.



As you'd all know, TA03's balldiff is dimensionally identical to TA01/2's balldiff... just less mass.
Same fits into FF02, M03, M04... M05 too even though that's got its own balldiff.

The "quick release" battery clip is shared with M01/2.


Other than that, everything is pretty much unique to the TA03 :)

Wow I felt like such a newb after reading this *-| Im so lost when it comes to all these part #s people know somehow :shock: I guess my problem is where to buy these things I know I can get a majority of these things from Ebay and asiatees but how do I know im getting the right bearings *-| so on another note I got in my replacement gears and changed out the spur gear but now I need to get a pinion gear that will mess properly any boby know what I need as in teeth count or is there a specific tamiya 1. I also got in my Tobee craft steering turnbuckles and camber adjusters by tobee craft as well :lol: should i maybe post some pics of the car ? anyone care to see ? This weekend I will be ordering a set of pulleys from MST the big boy 10tooth a 17 and 18 I already have 16 Oh so my TA03F DJ has ball diffs so can anyone break it down Barney style on how to lockup the rear diff and I do meen barney style pics anything video I will even pay for some to lockup a diff and ship to me of course if the price is right :up: lmao I am a newb and proud of it :ugeek:

People who look down on noobs should be looked down on for acting like they're better. Nobody knows everything and we should all do what we can to help out those who need it. Lol, that was my approach when I volunteered at the LHS. Makes more sense to help the hobby.

But um yah..

Slik I use google for finding things. To find out part numbers I use either my manual or I go to TamiyaUSA to check the parts listing, option parts, and data list. Then I go back to google (helps to have an extra open tab just for google) and search "Tamiya" followed by the 5 digit part number. Like if I were looking for G parts, I'd type in "Tamiya 50718"
-as far as pinions go, I believe the TA03 uses 0.4mod pinions. Tamiya part numbers 53101 53102 53103 and 53117. Each one is a set of 2. 53101 is 20 and 21 tooth. 53102 is 22,23t. 53103 is 24, 25t. 53117 is 26 and 27t. Some people will call 0.4 mod metric 64pitch. Thing is don't use regular 64 pitch with 0.4 mod gears, they are not the same.
-I love looking at other people TA03's, it always seems like no two are alike plus it sometimes gives me ideas for my car. Check out the TA03 gallery @ Driftercentral. Really sucks seeing some cool parts that are no longer available.
-You can lock your ball diffs by putting some "rubbber donuts" between the balls and pressure plates. http://www.drccentral.com/forums/index.php?showtopic=10175 Or you can use the diff lock for the TT01. Google "TT01 diff lock" to see what I'm talking about. You'll need G parts though because the DJ doesnt have the differential drum gear that holds it.

I'm a RC drift noob and couldn't care less. Everyone gotta start somewhere. Kinda like Call of Duty, once I get my attachments and perks it gets better. :lol:

That's why I said shelf the 03 and go with something more modern. You'll get tired of dealing with 10,000 screws to fix anything on this car.

Too late for that renegade I'm neck deep in mine. I work on real cars all day so RC cars are almost therapeutic to me anyway lol

Your listed drift chassis made me laugh. Waaaay back in the day i used to call my buddy's car the Broke some mo'. It was fast but that's all it seemed to do.

re TA03 balldiff... generally not a good idea to weld these into spools.
The outdrive splines are 1/2 width of what they are on the geardiffs
and they will strip the splines even quicker if you weld up this diff.


Gear diff locking options...

which replacement gears did you get?

TA03s have 2 different factory gear sets... white or black

Image

the black are the coarser gears, these use a 0.6mod (METRIC) pinion
aka Tamiya "AV" size same as TT01/TL01/anything that's not "pro"
Although they look close to 48dp (=imperial) gears, don't even try using them.

Image

white are the finer PRO gears that the plate chassis cars got.
You should use 0.4mod (METRIC) pinions with these white PRO gears
yeah they're pretty close to 64dp... its possible to substitute 64dp in an emergency
but best not to do it long term - gears run rougher than they're designed for

the balldiff pack comes with spare white PRO gears i think

Image





just to throw a curveball into the works... Robinson did make a dropin gear adaptor that took a 48dp spur
but this is pretty rare in the overall scheme of TA03 hard-to-find bits

LOL, DBoxes are taboo bro! You should be doing the driving, not the car. People who use them are posers, or at least that's the general consensus lol. I was curious once, there's a much cheaper one than the HPI.

Anyways, awesome car! It's the DJ that made people take Tamiya seriously. Maybe one day I'll have a NIB DJ. Hey, yesterday I noticed you're from the Bay. How often do you go to Sheldon's? Every weekend I've been meaning to go but I'm up in Vallejo and most of the time I don't feel like making the drive.

I wanna say the bore is 5mm but I'm not 100% sure.

Speaking of friction pegs, I think the traxxas clutch friction pegs work.

Image

I remember reading about locking a ball diff and something about them came up. For all the talk about the inefficiency of the TA03 drivetrain I just feel its better to use a diff lock in the G parts drum gear. Locking a gear diff or a ball diff just means you have unnecessary rotational mass. We don't race though, but that's just my 0.02. I'm a dealership tech and I hate seeing hack repairs.

Image

A more elegant and efficient solution eh?

compared to mass of the rest of TA03 drivetrain, rotational mass difference would be negligible ;)

yeah you can use locker pegs in balldiff; replace all the wavy spring stack with a single 1150 bearing or bushing.
Or just leave out the balls and cut 2 circle of thin rubber or card, insert between diff rings & plastic gear.

gear diff locker is best (T makes those plastic hexagonal inserts) but only problem lately is that
its getting pretty hard to buy new TA03 gear diff cases... easier to find balldiff sets nowadays

the gear diff innards are generic items, many models used them until they changed the splined outdrives
to the flat-sided oval type found in TT01 (as shown in pic above) - dare say those would work too
if you used their matching oval type outdrives.

In my mind that makes all the more sense to increase drivetrain efficiency in whatever way possible. But now that I really think about it, this is a TA03 and it's a very old car. Am I putting too much effort into an old, almost antiquated chassis? Nawwww it's for the love! :lol:

People add heavy diff pulleys on belt drive cars for gyro stabilizing effect. I dunno if it helps at all on ta03, since it has so many gears in the transmission.

a flywheel gyro "resists" change in direction, unless you're actively making use of its precession forces - not likely

gyro also needs to be large & free-spinning pretty fast, not start/stop... some RC bikes use gyro in the rear wheel


besides, if it doesn't like changing direction = piggy

you want piggy, you should try my TA03 twinmotor... its lardarsed at ~2000g,
definitely doesn't like changing direction! Its more a balistic projectile,
its specialty is holding sideways angle all the way down the back straight.

...or my VDF? Nahhh! Hours have been sucking at work this month. Always seems this way when school starts. :roll:

I've been reading around about body fitment problems with the 03F. A chart exists indicating what Tamiya bodies fit but what about other makes?
