• Is it going to do bad things if I use stronger Loctite (red vs. blue, 222 vs. 243 maybe? I can't remember which one they suggest) on my Rotor 3D+ with P2M?

    Basically, the crank/pm has been prepped, loctited, torqued to Rotor's specifications, twice now with different crank arms and during TCRs it seems to work a bit loose and starts clicking.

    I'm wondering if I can use the stronger loctite with no ill effects?

  • prepped

    Prepped how? Using higher strength thread lock isn't going to help if you're not degreasing the threads properly in the first place. As the threads are anodised aluminium, you should probably be using primer 7471 before applying Loctite. If all else fails, you could always ask Rotor to redesign their crank/spider interface to something which doesn't look like the primary design goal was to have the spider push off the crank whenever pedalling torque is applied.

  • Prepped = cleaned threads.

    I can get some of the primer - what does it actually do?

    I could ask them but that doesn't help the cranks I already own. If you have any suggestions for cranks that will do better than Rotors without requiring a new PM, I'm open to suggestions, I'm in no way attached to those cranks, they're just what fits the P2M.
