Question

What is the procedure to replace the input bellows?(I found this question on the internet and was wondering what the correct answer is out of interest)

  1. Remove tubing, old bellows and flapper assembly, install new bellows, connect tubing, install flapper assembly, then calibrate the positioner.
    Remove tubing, old bellows and cam, install new bellows, connect tubing, install cam, then calibrate the positioner.
    C. Remove tubing and old bellows, align the quadrant beam, install new bellows and connect tubing, then calibrate the positioner.
    D. Remove tubing and old bellows, install new bellows and connect tubing, align the quadrant beam, then calibrate the positioner.
