Tool head change out

We just set up our second 550B. We run one with small pistol primers and one with large.  We also purchased a tool head change out kit.  When we were changing the head we were concerned we may bend the fail safe rod as there is no real play in it as the head is pulled form the machine.  We did manage to change heads and hopefully didnt bend the rod.

   We are wondering if there is  something we missed in doing this or what the proper procedure should be. 

  Thanks

Pull the handle down on the machine first. Then pull the failsafe bushing down and out of the bracket, and swing the rod out of the way. Lift the handle up, then remove the toolhead. It is very unlikely you damaged the rod.

I change calibers a half dozen times a day with no worry about bending the rod. I just remove it from the powder drop completely as the swinging rod may cause to drop the block
