Drop in Motor first, or Steering box first?
So just use the blue, not the red. Thats what I have anyway.
Chase the threads to.........clean them up?
Like I said.
Chase threads with a tap and die to get rid of any dirt, burrs, previous deformation of threads for both the male and female threads. (You should be able to screw them together with your fingers until they bottom out). Dirt and burrs will "absorb" some of the torque that you need to get proper clamp load.
Then torque to spec.
It should be ok with clean threads and torque, but if you want to put some Loctite on there, either Loctite will due, red is better...
Loctite is more of an anti-backoff. It's the torque of the nut and bolt that holds the parts/joint together (clamp load). Loctite is not a substitute for torque, it is used to keep the nut and bolt from turning after you secure them. Like gluing them together.
You must torque to proper spec to get the joint to hold together properly. If you don't torque properly and then use Loctite, it can come apart as you will not have enough clamp load to keep the parts together. Loctite cannot make up for improper torque.
Always chase the male and female threads with a tap and die for used threads.
Always torque to spec whenever possible. Use Loctite if you desire...
