Having recently built a T4.2, B4.2, and B44.2, it seems that the snap rings are not as round as what I remember when I was running an SC10 last year. As mentioned earlier, cleaning is imperative for any adhesive to work- I have a mason jar full of acetone and a tea infuser (otherwise known as a Diff Dunker) on my bench and use it to clean all metal parts that will receive loctite or similar during a build. If one wants to use loctite for this application, I would suggest the green loctite as it "wicks" into tight areas- it's actually designed for bearing race retention after installation. I used CA and have had no issues on my brother's Yaiba Spec AE rides.
