A little caveat is appropriate here...
Loctite does come in various forms, some for permanent locking of threaded devices, some for eventual disassembly. However, none of the products are immediate setting except those containing cyanoacrylate. They require at least 24 hours or more to set up. A heat gun carefully applied can speed things up a bit. They also tend to migrate, i.e. from the pin to the shaft to the gear to the bearing, so apply with caution. I use Locktite 222MS for small fasteners that I need to get apart later. Also, a mechanical guy on our team has pointed out that a pin inserted off center to the shaft has a better chance of not shearing. That is to say, drill the hole so that it does not pass through the center of the shaft, but slightly to one side. I think he called this a "Dutch Pin".
