New Xmaxx 8S Finally Found The Noisy Gears! But How To Fix It ?

[@michaelvankirk3576]

Thanks! Great video Earl I'm glad you figured it out I wonder if anybody else had that same problem 🤔

[@earlmoorhead5555]

Appreciate the support seems a lot of ppl are leaving comments about this same area and issue 🤔wonder why I’ve not noticed this in the past 🤷🏻‍♂️

[@leonardholland6659]

Hi Earl, hopefully you will see this. I have the same problem on an XMaxx I just built. After seeing your video on this I started digging a little futher. It's the 20t gear. I took calipers and checked across the teeth. Measurement was larger towards the rear of the gear. This would explain why shimming the rear of the rear of the cover helped. I'm going to get a couple of replacements and see if that works. I've contemplated filing that area of the teeth, don't know if will induce wear. If you get an opportunity check it out.

[@gonzodetroitify]

So do you work the ratio out with smaller spur now or just don’t run 20t anymore

[@corti73]

Thanks!. Thanks for the videos, I use them to fix my RC's...

[@earlmoorhead5555]

Appreciate your support

[@nielsaarts6493]

Hey Earl, I have this problem also. I found it 2 years ago on a brand new xmaxx at the time. I also shimmed both bearings. It is not the most beautifull solution, but it works. I changed the bulkhead once because it cracked, but the problem is still there unfortunatly. Thanks for the video,

[@RC-Closer1313]

You gotta figure out that damn sound till the RC is quiet and smooth… we will all be watching and learning while you end up with one bad ass Xmaxx! Just an idea🇺🇸

[@brucehall6294]

Hi Earl, my X max is 3 years old made the same noise. I used foil under half of the bearings on both To keep shaft straight.

[@earlmoorhead5555]

My 2018 xmaxx orange was making this same noise

[@RON4RC]

Well it does seem to be quieter for sure. But i suppose you'll not really know till you run it. Great info vid Earl thanks. What a well built RC some amount of screws in that front end.

[@williamoleary9330]

Yea looked it up on their site that it does come with the 2085X which is nice to see. It’s under the “Features List” then “•Steering” it shows it has the 2085X. Good job by Traxxas there! My 2085X popped out after say 50 runs of mild to light bashing which was disappointing. I finally upgraded it to a better high quality “standard servo” and so far so good. Thanks Earl for this in debt look.

[@SchwaboT5]

Danke! Great Videos, great bashes. 💪👍 Thanks from Germany

[@chriscampbell9199]

sweet not too much with the diff's then because i wonder if been over greasing things on mine since it can be messy but you mostly did the same things an like you said it dose feel better just hope the run shows it when we have tinkered with the shims 👍

[@rctezluh42069]

Upvoted!!! my first Traxxas will be an Xmaxx this year! upvoted!!!

[@michigandirt619]

I have this same issue on my xrt. Idle gear tight mesh (spot) on the center diff. Used foil to lift the bearings on input shaft.made it a little better but if I leave the screws for the top plate just under snug it seems great. Very odd in my opinion

[@nofreerides7033]

I’ve had this same problem with my first Xmaxx few years ago and what I did was shim it up with fine layers of thin foil on rear bearing on Cush drive to soften up mesh on center diff… worked great ultra quite … and on second Xmaxx didn’t have this issue… I believe it’s luck of the draw on plastic molded parts … but should be caught on quality control 😳😳😳

[@earlmoorhead5555]

I used cardboard to shim it but wondering why 🤔

[@nofreerides7033]

@@earlmoorhead5555it’s what you had at the time lol… but aluminum has no give when compressed works great for shimming… look for to the quite xmaxx vids👍👍👍

คุณใช้เวลาเล่นรถคันนี้นานกี่เดือนถึงได้เปลี่ยน esc และ servo ?

[@daquonmason1307]

Question what if you put a spring in the middle of the driveshaft to push the two differential pieces outwards just a question

[@earlmoorhead5555]

Not sure

[@christopher0023]

I found the same problem few months ago, all I could figure out to do was to back off those screws of the cover a little till it got quieter. It think it’s only a temporary fix unfortunately…

[@earlmoorhead5555]

Yes I took the cardboard part number to the servo cut strips and put them under the two bearings to shim it up 🤷🏻‍♂️

[@kevinwalker7102]

Earl, have you thought about just pulling parts from your other xmaxx & switch things around to see if that makes a difference? If an area is too tight, rubbing/getting hot etc, if you just run it, it will eventually show itself. Lol! Good Luck!

[@earlmoorhead5555]

No there aluminum parts and are better quality I don’t know if I could tell what parts bad

[@kevinwalker7102]

@@earlmoorhead5555 Gotcha!

[@Frikkietube]

Heya, some KZbinrs says that they found that the new chassis of the xmaxx is weaker then the older version and breaks easier. This is from xmaxx fans like Kevin on his KZbin site. Have you found that it's true? Even the new parts that's plastic seems weaker. What's your take on it?

[@earlmoorhead5555]

@Frikkietube I haven’t noticed that the upper bellcrank cover has had this issue since they where built seems now it break quicker but who’s to say we are not landing worse 🤷🏻‍♂️

[@1motorvids]

My XRT has the same problem. I’ve replaced the center diff and idler gear along with the shaft for the cush drive with no change. Maybe the center diff housing is out of spec. Frustrating as my brain says. If I could just get rid of that rough spot!

[@earlmoorhead5555]

Yes I had to shim the Cush drive up

[@andyb9994]

Great work Earl, I'm picking up an Xmaxx Ultimate tomorrow I'm curious if it will have the same issue!!! 🤔 We will find out!!!

[@gonzodetroitify]

Did you have the same issue bud or do ultimates sound lots better now

[@G.J.G.P.]

Ok, i still dont own an xmaxx, but as far as i know from watching all those upgrade videos- the oem pinions were not held in place. If you pull out the diff, you can also pull out the pinion without undoing other parts. Its just held in place through the bearing and diff- ring gear.

[@sheilapeacor3224]

Can you tell me how to change a server saver on a Traxxas Slash 4 wheel drive

[@earlmoorhead5555]

If you search this on KZbin I’ve made videos along with many others I’ll see if I can link one 👍 it’s the bell crank that has the servo saver best to use hot racing assembly

I found that very helpful thank you very much

[@BashOnHobbies]

So what did you do to correct the center diff and idler mesh? Mines making a similar noice. I’m curious if that’s it. Ive had this thing apart and don’t see anything oddly warn so I want to try something 😂

[@markrusk2870]

I has same issue. I changed the gear cover for the Cush shaft sound gone.

[@stayunique91]

I use the same grease for my XMaxx. Gears and bearings.

[@chadbiermann3380]

Hopefully you can get that idler gear shimmed somehow so it wont be so tight. 👍🤙💯

[@Ragnarok881]

hey earl great video could it maybe be the new bulkheads since they changed them to fit x-maxx and xrt ????????????

[@earlmoorhead5555]

Possibly but that would be the front differential but not the rear area of the center differential 🧐

[@Ragnarok881]

true wasent sure if they changed both so tought i mention it :)

[@henryfoster3212]

Earl looks at new Xmaxx why kids look good on the new X-Maxx on green green 💚🍏 all right 👍 like it💯

[@Unknown-w6b8n]

Could the motor have moved ?

[@sheilapeacor3224]

That was a big help

[@markrusk2870]

Change the rear gear cover, mine did the same. New cover problem fixed…deformed some how

[@ryand4786]

Had the same noise on my 3S Typhon , it ended up being the rear diff . What a frustrating hobby sometimes

[@williamoleary9330]

I guess you’ll have a better idea what’s causing the noise in a long term test. Let’s see what breaks or wears out to maybe give us a better idea what’s causing it.

[@sheilapeacor3224]

Thank you

[@DJKadilac]

So basically, you’re telling me don’t chase the sound… I’m gonna SEND IT!! 😂😂

[@nicksolheim1]

Looking at what it takes to gain access for maintenance makes me NEVER want an Xmaxx or XRT.

[@overdosed51]

You think that until you own one. It looks way more intimidating that it actually is. I have a Krayton, a mojave, and an xmaxx. Xmaxx repairs are definitely more tedious but you do them wayyy less 😂

[@savagerc5752]

the xmaxx is amazing to work on very easy, and built with wrenching in mind.

[@lukerecore]

And they say that Traxxas r "user friendly " I beg to differ 😂

In your video before this one that I'm watching right now you spun the pinion and I could see a wobble in it.

[@earlmoorhead5555]

I’ll put it on a drill and check👍

[@glaanon4225]

@@earlmoorhead5555 I bought a 30t pinion gear from arrma through Horizon and it was machine incorrectly, it had a wobble so they replaced it and it had a wobble they replaced it again it had a wobble finally they just gave me a big can motor with 8 mm shaft and a 30t pinion for that. That finally took care of the wobble, but doesn't change the fact that three 30t pinions sent to me all had the same issue and they all came from China. I sent them two videos showing that the shaft spun true, and I changed pinion gears all in the same stream of video to show that my other pinions spun true on it, but the 30t pinions they sent me are in fact machine incorrectly and they didn't solve the problem and they're still selling them. So I don't buy pinions from horizon or arrma anymore. Sorry for the rant.
