Idea about solving E-Maxx tranny slop

[NeoSlayer888]

If the space where the gear engaged was smaller there would be less slop right? If so what if new gears wear made with an opening just slightly bigger than the fork. Does anyone think that would work? Also if it would do you think Acetal (Delrin) (http://www.matweb.com/search/SpecificMaterial.asp?bassnum=P1SM03) would work for gears. On Onlinemetals.com you can get a foot of 1” round for $5.73 plus shipping.

If you click on the Acetal (Delrin) above you can see the properties.

to me, the reason that section on the gear is so wide( wider than the fork) is so it can change gears easier. with it being just a bit larger than the fork, it would take more precision to go into gear instead of it just popping in. i wish there was a real answer for it, cause i just locked my trans in 1st gear( super glue) and it helps out alot but i would still like to hit 2nd gear sometimes when needed. but try working on it and let us know what happens :D

yea I dont like the slop. i just noticed that with the e-maxx tranny I got. Hope we can figure something out, cuz I too want to have a 2 speed.

I have dealt with Acetal at work and to me it would seem too brital to use for gears. It seems to crack real easy.

That’s interesting SlinkySam. Delrin just came to my mind because of these gears (http://www.rcrock.com/shopx/go.cgi?&shop=city&cart=48288421x20811&session=4095 7f44214d4fb7&L=eng&P=DLTXT-001). At you job how big with the Delrin that you worked with?

Here is a post with details of how I solved this problem:

Also has a write-up on the Rockroach project (which as of last weekend has been taken off the back-burner 8) )

It is a dedicated crawler so second gear isn't needed.

Reducing the size of the slot with epoxy or similar might work OK if for low speed applicaitons.

Would you start a thread on your project?

It would be cool to follow your progress :D

it's about time someone lit the fire under your butt JK to get the roach project going :flipoff:

LOL, well I have built up 5 MudCow clones in the meantime so I haven't been sitting on my hands (so to speak...)

No probs, I will start a thread on here about the Roach project.

Cheers, JK

Hey Neo I was thinking the same thing as you were with the idea of closing the hole on the gear that the fork slides into. I'm sure this would decrease the slack because when you take the back half of the tranny of and run it you can see the fork is fairly small compared to the slot. I was going to try filling in the slot with jb weld or epoxy then cutting a camfer on the slot and the fork so they slide together faster, just waiting on another maxx tranny.
