So for the dirt webs 3103-02/3104-02 (60mm) I would want the 61mm serpent wheels(500393/500395)? I don't want the 500103/500105 wheels?
Hope someone confirms this soon so I can place the order asap. Trying to get these here by Saturday for races.

Yeah the 60 or 61mm wheels are the same. Technically 2.4 inch wheels are like 60.9mm. So some manufacturers rounded down to 60mm and others rounded up to 61mm

I am not 100%?, but I heard the new MH will be out before the new year.

I personally think it's going to be like summer. So little information is out right now.

Can someone tell me what diff fluid and shock fluids to use on clay tracks? The car is on it's way but I am going to the hobby ship now so wanted to pick some up. Only a couple small/medium jumps, medium bite. Thank you !! Whatever weights that will help with traction. I always seem to have traction problems no matter what track I run on. I am still fairly new to racing so a lot of it is most likely driver error and throttle usage

The diff is a ball diff. If you're going to add the gear diff. I'd start with 7K. Some went up to 10K for a high traction surface.

For the shocks, try 32.5F/30R. I use PT Racing Oils so I'm really using CST now instead of weight.

Is 500192 the correct gear diff? How does the ball diff do compared to th gear diff? Wouldn't the gear diff get me better traction? Or no? Never used a ball diff before so I have no idea how well they work.

shagino

Yeah. That's the part number. What surface are you running on? I've got an extra gear diff that I could sell if you are interested. Also, Nexus was looking for a ball diff to buy if you are interested in selling that one.

I am running on clay right now but in summer it's just regular loose dirt. Would the gear diff be ok on clay? How much u want for your extra one?

shagino

Honestly, I think a ball diff will perform better on both surfaces but a gear diff will be easier to do maintenance on. I'll send you a PM in a little bit. Where are you located?

gear diffs would "work" on clay, but your turning would be better with a ball diff. In 2WD I'd always run a ball diff if on dirt/clay.

I'm hoping someone can help me out. I'm having trouble with the ball diff on my mm. I've built the diff several times, and am having trouble with the diff loosening up on me each time. Once I get it assembled, I start to follow the diff break in procedure that's pinned on the first page of the forum, and every time my diff nut loosens and will not hold. I'm obviously doing something wrong, but not sure as I'm following the steps in the kit when assembling the ball diff and transmission. The only thing I can think of is how I have the diff oriented in the transmission. The manual says to orient the adjustment screw to the right hand side. I'm taking this to mean that the diff adjustment screw would be opposite the main spur and pinion gear. Any thoughts?
Thanks for your time,
Matt

Is it possible that you have the thrust assy on the wrong side?

Never had the issue, just trying to give help.

Is this just during the diff break in procedure or are you running the kit on the track and it starts slipping? I find that I always need to make the diff a lot tighter than I think. When I do the allen in the outdrives and attempt to turn the diff gear, it doesn't move but I still need to go tighter to not slip on the track.

It doesn't matter which side the adjustment screw is on. I put it on the opposite side of the spur simply for convenience.
