Regarding my Caldera 10e, is there anything that I don't need to Loctite? I've got some medium strength Threadlock and plan to go ahead and lock all of the screws. Obviously, I wouldn't add Threadlock to moving parts, but what about wheel nuts and other non-moving parts (other than screws).
you dont loctite parts that go into plastic. There may be loctite made for that, but normal loctite will damage the plastic.
Wheel nuts should have nylon inserts which prevent them from backing off. You will still need to check them from time to time. If you do use loctite on them, use the lowest strength one you can find.
The main issue on caldera's is the 2 screws that hold the steering hub to the "C" hub. Some go as far as to glue them in. Others upgrade to the alloy "C" hubs so that loctite can be used.
