|  set screw keeps sliding
I put the metal yokes on the output shafts right on the flat spot when i assembled it. Ablut a week later and ever since, the yoke has play in it allowing it to rotate back and forth across the flat spot. No matter how much I tighten it down yes (threadlock too) the thing slops back and forth whenever I bind or go from forward to reverse and vice versa. Tried a screw in each hole to no avail. IT doesn't rotate around....yet but the output shaft is lookin' nasty! Any solution. Traxxas steel yokes are same as axials but longer pins,not better seating. Solutions????  |

Are you using a 1.5 hex "driver", or a dinky little "key"? A little key will not tighten the set-screws enough.  |

I knew we'd see these problems. Every manufacturer should always include 2 set screws for this, and on the CVD axle joints. Could it be your screw is bad? Can you remove it and try another? Sometimes the threaded can get boogered up and maybe thats why it feels tightened but you still have the slop. I'm also with NinJato...could be the tool used...those cheap "L" allen keys aren't worth much. |

Here's my take: The "dinky little key" works good for about two uses, then works just OK for about three more, then it's useless. Investing in a good hardened hex driver and you'll wonder how you ever got along without it!

I haven't had any problems with my yokes coming off ever since I used thread lock, and a good set of hex drivers are worth every penny |

No Problems here either, (touch wood, don't want to jinx it now) I did rotate mine backwards and forwards when i was setting the screw, this helps locate it properly on the flat. Brad. |

Are the link thread studs, the same size as the set screw? I just was thinking.. you could drill the pinion shaft and thread a link stud all the way through the yoke. Never slip again.
