locker issues solved

[1\4elliptic toy]

Ok I have had my creeper for a month or so now, I have ruined 2 "locker" cases because the red locking ring keeps "popping" out under load, It has happened many many times out on the trail. I am unsure if I want to get the option for the lockers so I dont want to weld them up or JB them or whatever.
I am sick of them popping out, even with the screw that holds the shift fork in place so tight it can't move they still pop out.

The old saying "necessity is the mother of invention" plays true here, I went to the hardware store and for .30 cents per axle I have made a "premanent" fit...thats removable later. It came in the form of a nylon washer that fits between the red ring and the bearing so it cannot slide out under stress. The washers fit so well Its like they were made for this purpose, they are the exact same size in width and height...

EDIT: if your going to do this make sure you take the locker with you to get the washer and MAKE SURE it is not any bigger around than the red ring or it will hit the axle housing and the bearing will not seat right. Mine were perfect they fit exactly like they were made for it..

That is a great, easy fix! I'll be at the hardware store tomorrow

Awesome... just got mine up and running and it is terrible. I am for sure going to do this.

Or if you dont want any more horrible differential problems you can weld your spider gears together, and in a crazy thread somewhere else, i heard that the axial AX10 solid spools even fit the creeper. I welded up my spider gears and they work amazingly great! Not only does it add that .--- of weight to your axles down low where it neads it, but it is amazingly impossible to break them that way!
Chears, good luck

So does the O.D. of the bearing fit inside of the I.D. of the
nylon washer?

No it dont, It gets sandwiched between the bearing and the redring.

But does anyone know why they are popping out? Mine only has the front one with this issue the rear seems fine. How can I fix this and still retain the switch?

The problem is the plastic around the pins cannot handle the "sheer" pressure that is put on it under heavy load, so it starts to fail, as it does that it twists out because there is no pressure forcing it into place. I assume that if you have the locker with servo the servo puts enough pressure on the ring to keep it from popping out.

I did the nylon washer mod yesterday. The size is 7/16". I pulled the
diff and took it to the hardware store and made sure to get the right one.
I plan on running it locked anyway so this is good for me. Thanks 1/4elliptic for the mod.

What needed is a small fat spring inbetween the bearing and the red ring. We need someway of putting pressure on the ring, to keep it in the lock position.

Only got 40 minutes of time on mine half to keep my eye on it or i should just go get the washer and be done with it

Hmmm, I assume it will at some point let loose, If it were me I would just do it, that way it does not strip out the plastic if it starts to slip, while you have it apart do the heatshrink on the axles.

I accually looked for a spring, but it needs to be sooo skinny I gave up and put in the washer, I think that there should be a spring that holds the shift fork in place until you get the locker servo.

I had this idea while I was initially putting mine together, but I figured Id give the locking diff a shot first.
Not trying to one up ya but I noticed that a large washer like you used causes drag in the carrier bearing. I used a smaller washer and just made the inner diameter to fit. Ya it takes a little bit of time to do but the bearing does not drag.
Stock set up.

shimming washer installed on diff. The one on the tabe is for the other axle.

Shim installed fully locked now.

Super glue the side gear to the carrier, it's fast easy and strong. One of my rings kept popping out becuase the pins were all bent, so venom sent me another ring and the pins were bent on that one too! Out came the super glue

dude, super glue wil come undone too easy, then you have a mess, break out the welder and weld em gears up

Thats exactly why I used a nylon washer instread of metal I figured if I used a nylon washer it wouldnt much matter, I will pull mine out in a week or so to see what kind of wear marks are in the washer. Nice work

Super glue has held up for a couple weeks now, broke an axle shaft before the glue, see how long it lasts.

Started having the pins being push through the red ring on mine. Tried to fix it then then the pins started bending. I'm running a brushless motor and I think the locking meck just isnt up to the task. I got a frind who runs a CNC machine, I'm going to have him build the ring out of one piece of tool steel, but I think thats only half of the problem. The holes in the gears that catch the pins I think are to circular at the bottom and it adds to the ease at witch the ring is pushed back. Im going to use an end mill to "square up" the bottom. If you want to keep the selectable locker I think the will be the way to go. Ill post up pics report back how it works.

This isn't a bad fix however my friend just purchased one of these and I helped him put it together and the first day of crawling I noticed the same problem... I run a machine shop and have a little engeneering experience so I think I may have spotted the problem. (at least to say I have apparently fixed his.) The pins that engage the spider gears are about .020 to .030 too short. I punched the pins through a little farther taking careful measurements to make sure that I didn't go to far and that they were all the same length. Now they more firmly engage the side spider gear in the diff and are still selectable. They do not seem to pop out any longer. Honestly I might try using the cnc to add more pins so that there is more locking engagement to the diff. This would spread the pressure on the pins better and increase the durability with something as powerful as a brushless motor. Three tiny little pins have to hold a lot of force at least 6 would be better.

Hope this helps all I can say is it worked for me.

Happy Crawling!

Well I think something has to be done here! I put a spacer in so that it couldn't move, today first day crawling with it and long and be hold un-locked it came. How is this even possible? I think I must have bent or broke the pins or the female counterpart that they slide into. This seems like a horrible design if ALL of us are having the same issue. Is it always the front on the rigs, cause my back axle is completely stock and hold just fine.
Oh ya no brushless here, just a integy 65t.
what gives? venom?
