To get gear ratios below 5.0 I use the following parts:

Tobee craft 41190 TB01-05 Spur gear 49T.

Tobee craft 42710 TB02-05 Aluminum gear holder

Kawada/Tobee craft 0.6 pinions from 27t - 31t.

Any advice on how to remove the fore and aft movement in the drive shaft? I'm sure this is adding to the gear stripping in the front diff but I am wondering where is the best location to shim.

Also, if I want to use 48p gears which spur gear adaptor is the best? The Evo III/ Evo IV or an aftermarket brand?

Thanks

teehomo, search back about 5-6 pages. i posted the part # for the new "Blue" (lightweight) shaft for the TB-02R. it has a thicker end (to hold the bevel gear) and its about 4-6mm (est) longer than the original evoIII shaft. that will minimize the play fore/aft for the shaft.

edit: here you go..part #49369

Does anyone have a list of 48P spur/gear combinations that work together without modifying the motor mount? FDR ratio's between 6.8 and 7.8 are needed.

Thanks,
Jimmy

Default New TB-02r

I just recently aquired a new TB-02r. It is a great kit. It looks like it uses the same ball diff that the TA05 does, or its close to it. A friend of mine has a TA05 with ball diffs. He recently had a problem where both diffs literally melted & fused everyhthing togther. They were put togther exactly as per the instructions. I don't want this to happen to mine & I was wondering if anyone has ever seen this problem.

I don't think the tbo2 and tao5 diffs are the same. as the tbo2 has a bevel gear and the taob has a belt cog in the diff.

I had a problem with the tbo2 diff. you'l have to be very careful when installing the rear roll bar mount on the rear diff cover. if you use the incorrect longer screws, they wil extend into the diff houlsingl and rub against the diff ring gear and melt them down. heh, heh , yeah did the same at a tcs race.

The hardware that makes up the diff is the same on the TB02 and TA05, the outdrives and pulley/gear differ (obviously). What the main difference is, with the TB02 the spring is located under the diff screw head and under the nut on the TA05, the TA05 diff screw doesn't wear, the TB's does.... funny that.

as for the diffs melting, then he had them set to loose or they backed off, or maybe just had waaaaaaaay to much grease on there.

58T Spur + 22T pinion = 6.85 - D Slot
58T Spur + 21T pinion = 7.18 - C Slot
58T Spur + 20T pinion = 7.54 - B Slot
58T Spur + 19T pinion = 7.93 - A Slot

enjoy

Default Indoor carpet setup?

Looking for suspension setup.

I have blue and yellow springs, and 40 or 50 or even 80 weight oil (Trinity)

Plastic shocks.

Thinking 1 hole pistons all around with 50 in front and 40 in rear I think blue is stiffer.. so that up front and yellow in back.

James

Chris, thanks for the info. Just want to verify that the gear mesh w\ 48P gears instead of metric is good with the above combinations. Cant wait to put the TB02R down on the track at TCS .

Thanks,
Jimmy

doh! misread your post. the combinations in my previous post are for the 0.6 module Tamiya gears and pinions. i never messed with using 48P. i am not sure how it will work. sorry about that.
