Arrma Big Rock/Granite 3S BLX motor and pinion access 

Heat the screws up as best you can with a hair dryer and it will soften the thread lock up a bit and possibly make them come out a little easier . I actually have a mini torch that I use in places that will not melt anything .

When I worked on mine, I was surprised how easy the truck is to work on. Good info for the newb's

Know it's a almost 2 Y.O. Video but helpful with my Kraton 4S which like your Big Rock I look at and the damn thing breaks. I'm kinda thinking that Traxxas may have been behind the design of this junk. I had a catastrophic failure at full speed yesterday. I think the only reason it didn't crumble was the brace. Hit cement so hard even the motor is cricked and it just makes a hi-pitched screaming noise now. Goes nowhere just sits. Ready to fix it and dump it. Head on with the video and I'm glad you showed the screw snap, lots wouldn't. At least we know you deal with the shoddy work as well.

Same thing with my Granite 4x4 BLX, after one 5 minute run in my flat backyard it was getting late, so I put the truck up. My wife calls me at work the next morning and says "I was dusting off your trucks and your new one is leaking fluid all over the mantle..I get home and both front shocks were bone dry. Tower sent me the parts to rebuild them, but instead of doing that I just got 4 aluminum big bore shocks from eBay/china and I haven't had a problem since.

Thanks for the vid. Would love a vid about wrangling the receiver wiring back in to that box. Or basic wire management on the ARRMA Cars.

Try takin it apart after it's got dust and grime in it. I had to take a small flathead to push/pry the motor setup out.

I did the same thing on the motor screw( twisted it off) rotated the motor one bolt hole and worked ok.

Use heat on screws with thread lock. That’s how it works

Such an easy platform to work on,might have to get this rig,they seem like they represent their motto of arrma tuff:)

Nice video. If you couldn't find any videos on how to work on this truck you didn't check out Arrma's RU-vid channel. They have several very good videos on how to service this truck 👍

Mann had some dirt and junk in it ended up having to use a flat head screwdriver to help pride out but it came apart pretty easy definitely good information

You were suppose to use a torch on those screws.

Thank you very much for this useful content it helped me out 100% step by step to do exactly what I needed to do thank you now my little buddy should be good for tomorrow letting it dry off for 24 hours

Next time use your soldering iron to heat the screw beforehand. Loctite removed.

A good trick for not breaking your screws in the motor is to run the car before you try to remove the motor from the motor mount that way the motor will heat the screws and loosen up the thread lock

My Granite 3s BLX Motor mount only shows 15,20 and 26 holes. Thats odd considering the same power module was used in all the 3s blx models. I just got my Granite 3s blx 3 weeks ago. My LHS tried to say 13t was for the brushed Granite

A touch of soldering iron on those screws with loctite will prevent snapping them. Not really fair to blame Arrma for that but I understand being pissed about it lol.

No joke, it took me about 20 minutes to pull out the motor and gears... When I finally got it out, I realized why... There were about 5 tiny stones behind the gearbox 😖😂

Hey, excellent video man. Appreciate what you do for the Hobby. I have a BR BLX and recently it started to make a loud grinding noise. I convinced myself that my problem was the rear DIFF, so I replaced it. I'm not much of a mechanic but I was pretty impressed that I was able to do it. Your video certainly helped me with the confidence to do it and for that I really wnt to thsnks you. Unfortunately, after the work to replace the Diff was complete and the truck was all put bat together correctly, the grinding is still there. Is it possible that the slipper gear could be the source of grinding noises? Id really like to find a way to diagnose the issue properly before going knee jerk and just blindly buying and replacing until id's fixed. Any ideas would be greatly appreciated. Thanks again for your channel and all the hard work in n support of the community.

What size is the motor shaft? What tooth and pitch is the pinion gear and spur gear?

Man I love my truck but to be honest with you it's been hell trying to keep that thing on the road LOL as I can see in the video as the screw snapped 😂💪🏽🙌

Huh that's weird I have been been beating the crap out of mine the past 3 days and have absolutely no issues at all

They should make platnuim editions

Nice video mate that helped me. Nice one

Can you please help me with a problem with my granite truck malfunctioning

Seriously the f pull tab broke off?

i did a mod .8 and went 35 tooth spur on spool and 29 tooth pinion and this shit flies but needs to be widened so make a video widening this thing

Just use a larger pinion and your good to go!

Arrma Blx or is the car traxxas vxl ? Very confused dude 😕 years from now spec want even matter if we keep this up! 🤔

Most them leak i wasnt crazy about shocks myself but for the money if your a basher its still best rtr . Rc out.

That wasn't Arrma fault it was yours you knew you are supposed to heat up the screws if Arrma didn't put thread lock the motor will shift with all the power and torque

Thanks for sharing the video!

Appreciate this video and please share any tips about the shocks on these BLX because I'm having issues with my shocks continuously leaking

Is the shaft call drive shaft

Hi, what happened with the leaking shocks? Were they leaking and did you put new seals in them?

Thanks dude!

I am scratch building this truck from the parts list (super fun btw) - I am having an issue where my motor mount won't go all the way in at the diff connection point. My troubleshooting makes me think the spur/ slipper gear has something obstructing it...anyone else have that? The clip is sooo close.

good info. Good stuff

1 screw to take the motor out? Wtf is this witchcraft. My truck news 50 screws to be able to see the motor XD

The red piece is not moving... I’ve tried literally everything

Hey man does the big rock 3s come with 32p spur and pinion? I was going to get the granite mega 4x4 and just brushless convert it all I see different is plastic turnbuckles but then I see the mega had 48p little pinion and spur and they force you to use their motor mount spots for mesh so I wouldn't know what 32p door and pinion to use. Lol so long story short does this big rock come already with 32p gears? It looks like it in this video but I can't really tell thanks man

I watched Stevo D 313 video then this one and by F******D it wont budge that easy lol Ah well now i know im doing nowt wrong lets try again

Do these stock ARRMA Shocks, do you have to add any oil to them! I have to replace one and I was not for sure if there is any oil in them?

My fingers...

Lol 25t would be meme grade. 168mph XD

Dont feel bad went up grade hubs stripped grub screw same thing brand new truck

Las piesas 1/10 de tarasa le sirven a una granite 3s 1/10

The Mega versions of Granite and Senton are 💩 nothing fits together properly when it comes to the Gears

Unbelievable only bad thing about arrmas throwing together wires in wrong place and you must use heat even soder gun i dont know what kind locktite using but serous industrial shit

Una mierda se hace así

Well sorry about the snapped screw, but at least it not losi who strip out all your bolts before it even goes out lol, literally half the screws on my tenacity are stripped and I can't do shit with them but buy new parts when I want to change something. I went to change my diff fluid in my center diff yesterday and all the screws holding my spur on were stripped exept one lol so I guess I have to buy a whole new center diff and spur just to change something lol dumbass horizon hobby workers.
