It's also useful to check your motor bearing if you are chewing gears. They need replacing often if you jump big or get them wet. A sloppy motor bearing will never mesh right.
I purchased an XMaxx over the summer and went through pinions and spurs like mad. The pinion kept slipping off the shaft, leading to catastrophic destruction of the pinion and spur. I used every flavor of loc-tite in existence to no avail. It turns out, the flat spot that the grub screw would mate with was actually slightly tapered. I confirmed this by measuring it with calipers. Heat cycles would just push the pinion right off after a couple battery runs. I didn't have the tools to properly re-machine the flat, so I drilled a divot in the shaft for the grub screw to seat into when it's fully screwed down. I haven't had a problem since. The downside to this is you're likely limited to one brand of pinions, so they all have the grub screw in the same location.
@@wyshtechairsoft Robinson racing but thinking of trying a arrma D bore pinion as I've heard they stay on really well. Found a 16 and 20 tooth D bore for like 5$ on ebay for both
With pins set in correct position, does yours have that bad cogging sound? Mine is stock......... 18/54 or what ever the☝️spur is .. biggest one anyways.....that plastic housing guess has alot of flex for such a big rv truck...my outcast 8s, smooth as butter...roll tires with one finger...Xmaxx..takes 2 hands to turn all 4 wheels..both our X-Maxx's like that
This Xmaxx cogged at well but it wasn't bad. Ive long since sold the RC but it was running like new after repairs were made. I bought this thing used and busted so I got a really good deal on it.
It depends on the gear ratio you are going with. Move the pins to what gear set you are going with and then place your motor back into the rc on the pins. Hope this helps!
I got it as a trade with another RC for a 1/5 scale hpi I had. Anyway, I discovered the previous owner swapped the pinion gear and didnt set the motor correctly.
👍 switched mine to 20/50 and couldn't figure out how to adjust it... thank you !!!
Make sure you clean screws, greas it then put it all back together
Thanks for the quick n easy walkthrough, bro
No problem! Glad to help!
Thank you 🙏 for sharing no criticism here you did a great job well explained .now I’ll try and do mine . Great vid 😎👍🏻🤙🇬🇧U.K.
Anytime dude! Constructive criticism is welcomed! Thank you and glad to help. :)

Where’s the motor bearing?
Easy to follow. On point. Nice work
Thanks for the input!
Back again just dun mine nice and easy thanks to your video. Thanks from U.K. 🇬🇧👍🏻😎
Glad to help bud!
@@wyshtechairsoft yep thanks an fitted green led light bar .👍🏻😎🇬🇧
Nicely done brother, the only video that helped me.... subscribed... thanks 🙏🏻 GOD BLESS
Hope to see more videos of you explaining everything as in this video 🙏🏻👍🏻
@@josefcalderonromero8452 glad it helped! Thank you for the kind words!
Excellent video well done 👏l just Purchased a xmaxx l was wondering about the pins all good now thanks 😊
Anytime bud! How are you liking your Xmaxx?

Ive heard of this happening if you dont have the motor slotted into the chassis correctly. Though great idea of fixing the problem!
Thats what I did too and your right about being stuck with one brand but honestly I found one I really liked and thats all I use
@@Todd_G_FPV What brand do you use?

@@Todd_G_FPV If you dont mind me asking. What gear ratio are you running?
Great video!
Thank you!
i did this and it instantly blew apart my pinion gear, but it did work the second time
Must of been a bad pinion?
Wow! Good job!
Thanks!
Awesome work 🏎💨💯😎
Thank you bud! Let me know if you want me to cover anything.
Awesome thanks for the help
No problem bud!
Thank you!
You're welcome!

What size is the allen wrench for the set screw? Thanks
I believe it was either a 2.5 or 3mm
mine did the same thing lol

Thank you!
buen video amigo, buenos detalles!! 😁😁😁+1
yes okay nice video not full the pind need on E correct what hol you need on the motor self???
It depends on the gear ratio you are going with. Move the pins to what gear set you are going with and then place your motor back into the rc on the pins. Hope this helps!
6 months later, how does that gearing hold up?
Great! Haven't had any issues since I did the replacement.
The smaller the gears the faster or other way round?
Yuppers! At the sametime it increases the stress on the motor/esc.
The xmaxx has optional pinions and spurs, for the spur a smaller gear is faster, for the pinion larger is faster
How do you end up with such nasty situation to start with?
I got it as a trade with another RC for a 1/5 scale hpi I had. Anyway, I discovered the previous owner swapped the pinion gear and didnt set the motor correctly.
no need to put grease? mate?
No grease is needed. Traxxas doesn't recommend it.
@@wyshtechairsoft ok tnx my xmaxx is 3weeks old and its truly a beast
@@rcboy4652 enjoy it! They are great trucks!
What brand is that new spur? Traxxas?
Yessir!
pff😟😟🤨🤨i need to do this too i broke my gear 54 and want do 18/46 i dont now how to set the srews i dont understand the video its my first rc car
What do you mean set the screws?
i use 18/46 and i broke on 5 sec and i set the pins on E xs i set back 18/54
As long as this has been an issue, you'd think traxxas would have fixed this engineering issue by now. Traxxas quality is going rapidly downhill!
Geeezus dafq did you do on that spur, chew on it? 😂😂😂😂😂😂thats shit all fucked up!
This was a XMaxx bought used. It was a deal I couldn't pass up. haha
@@wyshtechairsoft hell yeah! Hope everything is good now. I just freakin burned my xlx2 esc today! FML, in had it on the xmaxx for a year now
@@oscarmike131 sounds like you got a good life out of it!
@@wyshtechairsoft yesh
