Is it required to replace the clamp with new ones when removing the old ones off?
Answer Hello Gabriel. No, it is not required to replace the clamps unless they are damaged.
Is there a special tool for removal and/or installlation for these clamps (Part Number: AP3919286)?
Answer Hello Jason. You can use channel lock pliers to remove the clamps 8540092. You will pry the clamps off by pulling on one of the tabs on the sides of the clamps. Then when installing the clamps, you will position them on the outer tubs and press them into place. Hope this helps.
