Mugen MBX7R Eco thread!

I am starting to get some gear slipping in the front ring/pinion on hard braking. After inspecting the ring i see some minor rounding. To address this, I shimmed the ring side, hopefully moving the ring closer to the pinion, but havent had a chance to test it yet. Assuming i am still having a problem, the next step would be to ship the pinion? If so, do you guys know what shim/part# to use for the pinion shim?
Thanks!

When the gears(car) is brand new I don't, after about a couple hours on the car, I might ad one shim depending on the mesh...after a year of constant driving, I will ad another shim..my sons nitro buggy has 2 years on his drive gears... Keep in mind that I also replace the bearings so the diff sits in the housing solid..

What I have done with Mugen diff gears and never had a problem is as follows.
On initial build, I will set the gear mesh with shims if required. I will then run a solid one day race meet, then recheck the mesh at the end of the day. I have found they tend to bed a little over the first solid race day, it could be matching in of the gears, or heat on the diff case, if could be a variety of different things that cause the tolerance to open a little, once the first race meet is done and reshimming is done, I rarely have to reshim again though I check every time I rebuild the diffs or pull the front or rear end off. It takes a split second to check.
With my MBX7R Eco, the build mesh felt a touch loose on the front gear and quite loose on the rear, I tried the initial front build with a shim but that made it too tight so removed it, the rear needed that 1 shim on the crown gear side. I'll run 3 x 7 min qualifiers and 2 x 10 min finals at the next race meet and once I get home, recheck the gear mesh then.

If your gears are slipping, there is no other option but to replace the gears..shimming is only a temporary fix..I'm only assuming that your gears are getting a flat spot and are worn? To answer your question,yes shim your ring side,I would put 2 shims if it's really worn, until you can replace the gears.. I believe most other cars use the same size shims..

I know it's a silly question but I'm curious if I could get the proline nitro or bitty designs nitro body to fit. Anybody happen to know?
#969
Thank you sir. Anybody have any thoughts on overdrive under drive? Looking at the option parts and just curious about opinions

Also, I'm digging this...

If the "force" body for the serpent fits then I am wondering if the "fighter" does as well?

Exactly what car is that phantom body for? I have it for my eb48.2 and love it..
