Default Diff balls

Im just wondering, how long should the standard diff balls last?
Ive changed everything except the diff balls in my rear diff and it still feels extremely gritty. Very strange.

Most of the time a diff is crunchy is because of the thrust ball assembly. I don't have a evo3 but if it uses the standard tamiya one piece trust bearing it is kind of hard to get it clean enough. I would soak the thrust assembly in some cleaner and blow it out with compressed air and grease it with some good tacky grease and try it again.

i agree with what KINGZJ said.
i also had this problem to some degree with my old car.
what u have to do is remove the diff balls and clean thme the way u like and also clean the diff's very thoroughly.normally if u just clean it with the balls in ,dirt will still get attached to the balls.

Post EVO 3 4x4 config

Difuser,

I made some of the changes we talked about to try and come up with a decent 4x4 config for the Reedy...so far so good.

Still seems to park a bit at mid corner, but shows some promise

well, had my first run with the evo3 with ball diff up front. I set up it up 2 camber, 0toe, a block rear, bout 6mm ride height. yellows up front, reds out back. It understeers on power, but rotates nicely off power. ran with a Monster PRO geared 72/24, 72/25, 72/26...it got slower with the last gearing, but the 72/25 let me get a 12.8 sec lap at my track! Its fast! Its smmooottthhhh! although I did notice some scratches at the very front of the chassis and one on the rear of the chassis...guess I better increase ride height a tad. Next time I'm going to try the 72/23 and keep going lower to see what it does. THat monster motor is weird to get a nice gearing. I gotta change the setup....I need more onpower steering. IF y'all find a good setup for bumpy outdoor asphalt, please share.

hey guys, just out of curiosity.... I'm geared at 72/25...what would happen if i switch to a 66/23(basically the same ratio)?

do I get more punch or do i get more top end? or both?

I ran my EVo this morning at my track and carpet was cold from not being used in two weeks and ambient temperatures in building of 40 degrees!!! So-car had a on-power push that was hurting the performance, but it turned in well enough and seems like it is carrying the speed through the corner untill the front tires give up the ghost at mid-corner. But i know how to fix that real quick and when get more testing done with it-I'll start posting my set-up (if its fast).

I geared 34/90 with 2.35" tires on a Monster. Motor was too hot-so i think i need to go down one tooth for starters. Car was smooth and whiper quiet. I think i also need to relearn driving with a one-way. This is my first car with one have ever had. Maybe I just need to lift earlier and power through corner like with a solid axle.

Top end. Unless you're running a torquey mod motor you won't get any punch out of that gear combination (I almost learnt my lesson the hard way).

I was reviewing the "smoking" carpet setup posted a couple pages back and I have a few questions.

1- Are the 1.5 mm spacers used on the rear toe blocks from the "53539 Tamiya 5.5 Aluminum Spacer Set" package?

2- The Front and rear width are said wider. Front by 1mm (blue spacer) and rear 2mm (red spacer). What is the part number for these spacers?

3- Shock oil weight is referred to as "400" & "500". Anybody know what American weights these translate to?

4- Can someone explain the "rebound stroke" measurement and how to take it?

Thanks!

1. yes the spacers are from the 5.5mm spacer set.

2. the spacers are part number 53448.

3. i think that i posted that i used 40 and 50wt oil, but in case i didn't, i used 40 and 50wt associated oil.

4. to measure the rebound stroke, you remove you wheels and shocks, place your chassis on something flat (setup board, glass, etc.) and then measure from the top of the axle to the board.

hope this helps

peter

Peter and everyone else-has your rear diff been staying tight? Mine has loosend up three times now. Also-how tight are you running yours? in other words-when you fully tighten the diff screw-how far back do you unscrew it (1/8, 1/4 turn, etc.).
Thanks guys,
Ray

loosen? why? i just tightened it up and thats it.... maybe the loctite helps

its funny though, the rear diff is supersmooth, but the front diff I put together has a slightly crunchy feel and sound. Less than the evo2, but crunchy nonetheless.

ummm bout them spacers...why dont you just use the plastic ones that offset the wheels? Its basically the same thing. I think integy also makes aluminum clamp spacers which offset the wheels from 0 to 5mm...very nice.

Peter - Thanks, I'll give that a shot and order those spacers.

rayhuang - so far my diff is holding its setting in the rear, I have the one-way in the front.

Aluma - I'll check that Integy stuff out.
