Wow, trick new ackerman steering post and adjustable sway bar rods. Is that new on the MSX or somthing new for TRF?

yeah i reckon go tamiya! :nod
Tamiya is the leader of TC
Tamiya designs and all the other follow!
But tamiya is still ontop

Ok i have a few questions for this thread....meaning i need a lil help. Ok for the MSX what Rear belts do you run and how tight do you run them?
Also How do you keep a rear diff in your car? Is there any special way to break them in or anything special anyone has figured out that might help?

Any help would be great!!! Thanks

You don't need to break in the diff. They are good to go.

For the belts, if you see it skipping or wobbling, maybe it's time to tighten it.

hi anyone have iussue with the front belt rubbing the servo posts?

Are you confusing this with the Yokomo BD forum?

K, i am asking these questions in here cause i thought i would get an educated answere, instead im getting common sense answeres,well common sense besides the part about not having to break in a diff. Look i know what im doing even tho i am new with the Tamiya car, but i was just asking if anyone knew anything "trick" or special to do so that the diff/belts last a lil longer.

I don't think there is any special way of doing it unfortunately. I like to rebuild my diff quite often actually, and with the MSX, its a breeze.

numan , I'm still having diff problems too. I still have the feeling that my diff is not grabbing right away or my belts are slipping and I replaced everything in the drive train.

Rod C or Cory lewis we need help

Josh, try this stuff from Nexus Racing when building your diff.
Black Grease
Diff Lube
For the belt issue, ditch the white belts and run the black belts.

Josh, this is Rod...here's something that I always look at when I build or rebuild diffs. If you look very closely at the thrust bearing, you'll see that one side of the inner race has a slightly more conical shape and the other side will have a slightly flatter shape...We've been told that diffs turn out better when the flat side faces the cap screw the concical section faces the nut on the other side of the diff. I pack that lil bearing with Mobil1 grease (lifetime supply for like a buck at Pepboys). I use the Associated silicon lube (the red label grease) for the diff balls (good combo so that there isn't any excess diff spin, but may have a bit too much stiction). I save the Carbide balls for big races and use the relatively cheap "lightweight" balls for club and practice. Another important thing is to have a clean diff plate whenever you build/rebuild the diff. Flip it over if you need to lol. And when you reuse diff balls/thrust bearings...use A LOT of Motorspray to clean them. When you initially tighten the cap screw, don't crank down on it right away, just do it in like two-three steps and work the diff at each setp by spinning it in your hands. Do the final diff adjustment in the car. I hope this helps but please know that I am not exactly a world class diff builder ha

On the belts the rear white ones get tore up rather quickly with 6-7 turns and there really isn't much I have done to prevent it...sorry can't help you there. It seems that some belts new out of package require a different belt setting...I typically start all of mine at two clicks tighter for modified.

XingXing-yes the belt does get close to the servo stay and on occasion it'll rub but it's not that big of a deal. One of my original 415's no longer has blue anodizing on that side of the servo stay

Thanks everyone for the help!! I will have to check my thrust to see if its in right.....

I bought 2 MSX alloy diffs with no instructions. No problem in building them as they build the same as the standard ones but I can not see how they're adjustable in place as it uses a standard cap diff bolt that you can not get to with the drive shaft in????

Evening all,
Does anyone know if the yokomo 15 x 10 BD outdrive bearings will fit the 415 (replacement for the 1510 one)? I've had a 1510 bearing go bad on me last night, got another race next weekend and haven't got time to order one in from accross the seas.

Cheers
Dan Chambers

Yes
