Sorry, I can't really help as I'm not a nitro guy by any stretch of the mind, and I haven't ever had issues like yours on my smaller scale electric rigs. I can say though, take the screw/grub screw out, clean off the threads with rubbing alcohol or something, clean the drive cup threads with a Q-tip, and make sure the grub screw is on the original thread, and screw it in real good and tight with a good driver. If all else fails, Loctite exists, but only use purple or blue Loctite, NEVER the red stuff! If you use the red stuff, those grub screws aren't ever coming out, but when you need to take them out, you'll have a heck of a time heating up those little screws, taking them out, and cleaning them!
Yeah, I’ll take a few today
It’s the cv pin that’s coming out, it’s a pain in the Butt, if I can find some heat shrink that would be my next betI never had that much issues with mine ,every now & then they vibrate loose an fall out ,I just replace them
as I hate putting loc- tire on those grub screw pins!
I've seen people use that shrink wrap over the hubs though!..
I’m currently using red loctite, and not even that is keeping them in
That's crazy...in that case, sadly, I can't help you more. Maybe try going to your LHS and see if they can help. Try the heatshrink recommended my others too, if that doesn't work, just get some new CVDs, yours might be worn, and thus the grub keeps backing out.
Driveline
The ones in the barrel with the hole that the pin goes through, the grub screws there are the ones that keep backing out and making everything fly everywhere
Yes I’m using 271 and she’s still pulling off lol, it mighta snapped my aftermarket pin tho, so who knows
I was starting to make my own with 2 e clips on the pin, one on each side to secure it and the grub screwYou can also try the 8.0 version drive shafts as they got a snap ring around the cup to secure the pin!..
Yeah, he was the Red, 272 stuff, that's why I was surprised! Talk about determination...those drive CVD grub screws REALLY want to come out!
I have the blue 242 stuff and it works fine.
I have never had to use red on anything….. RC, dirt bike, car, etc. I’ve used a ton of blue and it has always done the job for me. I feel bad for bakershaker78. He’s got a real head scratcher on his hands!Yeah, he was the Red, 272 stuff, that's why I was surprised! Talk about determination...those drive CVD grub screws REALLY want to come out!
I actually just got my first ever threadlocker, the blue 242, about two months ago, before that, there wasn't a situation that NEEDED Loctite, though I do wish I'd bought it earlier for some other stuff I've wrenched on. I suspect the CVD threads are worn, dirt, or stripped, and the grub screw might be the same. @Bakershaker78 might be best off getting new CVDs, that might help. Other than that, I can't believe I'm saying this, but if new CVDs don't do the trick, he could try a little drop of super glue. I'm hesitant to say that, it's a last resort, as CA glue is a pain to take out (worse than red Loctite sometimes!), and it's messy, ect. But it is there...If even new CVDs and CA glue don't do the trick...tell me @Bakershaker78, and I might have an even worse, even more frowned upon idea...in fact, it's so bad, that I've never heard anybody mention it, and once you do it, the grub ain't coming out till the end of the world!
These are fresh grubs after I lost both front and rear barrels while the hobby shop was helping me tune the 3 needle carb on it, so I’m sure that they are clean and not stripped
If the red locktite and new pin don’t work then I’m sending the dual e clip pin idea, I’m decent at running a Dremel in a mount and a file as a mini lathe to make the e clip pins
Not around the drive cup, I’m going to do it on either end, I’d rather make a longer pin, then cut down the aluminum drive cups making them weakerI thought about running a groove around the hubs an adding a snap ring ,I think it can be done!..
