A question about Spool and shims.

According to the supplied intructions the Tamiya Spool requires four 10x0.3mm shims.

Unfortunately they are not supplied in the package.


Can I use six 12x0.1mm shims instead of the four 10x0.3mm shims recommneded in the manual?

Cheers everyone.

Not sure how they will work. If they are 12x15, it should be fine.

That amount of shims is a recommendation of where to start. Shim it tight yet with minimal play.

Hey Guys,
Been running Buggies for a while now, but decided to pull my Tb-03 off the shelf. I plan on rebuilding the shocks this weekend, but can't for the life of me remember the correct weight oil to use for the TRF shocks. I know it depends on a lot of variables, but what would be a good starting point (front and rear)? Any spring recommendations would also be appreciated
Thanks,
SoCal

40wt is a good starting point with the TB-03 chassis.

I prefer to use a slightly heavier spring on the front and a medium spring on the rear.

This tends to produce a car that understeers / pushes especially when running a front spool.

I find this sort of a setup good because it's very predictable.

However, on a longer / flowing circuit it's probabably not optimal.

cheers.

finished Diff:


It feels really smooth and moreover now it can stand 13.5 with boost!

You need:
Tamiya 51438 TRF592x Ball Differential Gear Diff
12pc 3/32 or 2.4mm Diff Balls

--> file about 0.5 mm off of the end of the shaft from shorter diff joint



--> don't use the 0.5mm shim between the 850 bearings

have fun!
Looks like my Ev05 getting an upgrade "asap".
This sounds realy good!

Anybody know a good (cheep) source for ceramic 2,4mm diff balls?

Anyone other tried this modd already? What about the shimming of the diff?

Hello,
I'm from Austria too and I've used this mod now for a while - on both tb03 & EV05MS.
I don't know exactly the outer diff shiming, but I guess I used 0,4mm on one side and on the other 0,3mm. I left out the inner 5x0,5mm shim between the diff halfs (otherwise I would have had to remove more material of the diffhalf-"pin")
btw. I bought Vampire ceramic balls from radra.at - I think together with shipping it was only 9-10€

regard,
Oliver

I've looked there and can't find them anywhere! I even looked for 415/416 version and still nothing!

Here's the out drives and there may be cheaper sources. You can always google the part number.
