O'Ring of the pivot balls of My Outcast 6s goes out

[sebcbien]

Hello everyone,
Small question,
I'm new owner of an ARRMA Truck, it's a 6s Outcast, latest model.
I have fun with it, but I lost one front A arm and when I tried to tight it down, the O'Ring of the Pivot balls keeps trying to "escape" when I thight down.
the ball is still loose and the orange O-ring is already out of the tread...
I tried to see how it was done on other pivot balls...and when i thight them down back.. the O-Ring goes out also ... WTF ???
Any help or advice needed please

Are the treads okay? Maybe there is a bump and it catches the oring

I had similar problems with mine, they refused to go in straight and cross threaded... then the O rings did the same thing as yours.... maybe you damaged the threads a little like me?

I ended up buying some HR steering blocks and pivot ball cups.. problem solved.

Lightly bevel that area with a exacto knife

Yup simple fix. Wet the o ring just water. Put it in like you are using a tap... turn it till it bunches up a little then back off.. turn it more till it bunches a little then back off. It will go in every time.

If you choose to upgrade the Hot Racing are great. M2C also offers a perfectly engineered solution but I haven't picked a set up yet.

Here are the M2C ones if you wish to save a little money. I plan to pick some up after hearing all of the positive feedback.

Here are the Hot Racing that many say are the best Arrma product they make for 1:8 scale.

ok, yes treads are ok, it's the same for all the pivot balls and the car is new.
As for buying M2C... uhhh well, thanks, but no... uhh I'm in europe, shipping only cost an arm...
I know ARRMA are better stuffed with M2C parts but I bought it because it was supposed to be strong and "cheap", will not start to buy 300$+ of stuffs. it's 550€ here and I already paid 50€ to change the radio to a Tactic one and also changed the servo.
I'll try with water, I already tried till it bunches up a little then back off but with WD40 and also dried ... no luck, the pic is the better I was able to do.
Thanks !!
Will keep you updated.

Even in Europe, "cheap" still comes at a price.

You can buy from @Badtouch The basher who is based in the UK and a M2C distributor

didn't know this address, thanks !

I ended up splitting my O-rings due to this and had to resort to using PTFE tape like many others on here, which does work well... so thats another option for you if it doesn't work out for you.

ok, just spent 1/2 hour on this, and well my conclusion for my first ARRMA repair is that this pivot Balls system s*cks, ... BY DESIGN as it's unlocking by itself, then o-ring goes out, then after removing to clean it you have 33% chances to cross thread it...

If I have to buy those M2C and new streering hubs or the Hot Racing because I "cross threaded"... after a Tactic radio and metal servo ... it became less and less a "cheap" RC...

Here is how it happened: First I cleaned the o-ring with towel paper, then brake cleaner, then added water then cross threaded and still no O-Ring in place..

I read this later on the M2C part description:
"The nuts are designed to allow you a very easy start to avoid cross threading. "

I'm not a fanboy of any brand, but come on Arrma...

That said, what's the purpose of this O-Ring ? is it mandatory ?
thanks for all your help guy's

Yep, its not a very clever design. I think the O-rings main purpose is to create a friction fit to make it more snug to stop it backing out. PTFE tape will do the same job...

Why don’t you grease that o-ring, not clean it? ??‍

 

[Clubin]

It’s like a hurnia. Push it back in with a common screw driver

 

[sebcbien]

tried greasing it before with grease, WD40, PTFE... the first attempt is with the O-Ring "greased"
In this thread they say to try with water, but I have to clean grease before, and just give a try before trying with water (you do not see it on the vid, but the last attempts where with the O-Ring and water)
