Shim the one-way FIRST...so that you have just a tiny amount of play side-to-side...without the crown gear in the case.

Put the crown gear (the little one) in the case, then the one-way.

Move the shims from side to side until you have very little lash (free play) between the one-way and the crown gear.

Both boxes, shaft and spur holder must be in place and assembled to check the lash, because the shaft holds the crown gear in place.

I don't run any shims on the crown gear. Even one will make it jam into the one-way gear and bind.

well wouldnt u need to shim the box to get the least amount (logically thinking) also i dont get the point of shimming the one way before i put the crown gear (bevel gear) in... Dont i have to reshim it later anyways>>??? thats for the reply i got some of it.

Because you can't really tell how tight you have it with both gears...if you do the one-way by itself, then you have the total number of shims already, you just move them around ot get the lash right.

It always seemed to me that if I tried to shim the crown gear "deeper" that it bound up immediately. The only way to know for sure is to try it, but I never had one that needed to be shimmed deeper.

Our P2705 EVO-III gear adaptor is counterbored to support the gear from the center all the way out to the outer lip, The plate is the entire diameter of the gear. This is why the gear is supported enough to eliminate all stripping caused by gear flex which is the main cause of the EVOIII gear problems.

Thank you,

I used the xenon one way gears, biggest piece of crap ever, unlike the tamiya plastic oens which gradually wore the teeth down. The xenon gears just have the teeth rip straight off. Terrible, getting very annoyed with the evo now.

I PM'd you earlier...but FYI for the rest of you guys...you can use the EVO-IV MS center support. There's also Xenon one for the IV on there (@ speedtechrc.com)...they both use the same "J" parts (battery mounts/brackets). I have one in my blue-kitted "III".

Run the longer shaft, updated One-Way gear, and shim it correctly and you shouldn't have problems...



And just out of curiosity...

Has anyone had recent success with this chassis? Or has everyone "moved on"?
