I have a seized trim cylinder. i have the old two cylinder style with the on board pump. I purchased a new cylinder and I want to swap it out. but... i’m not sure how to remove the pins that holds the cylinders in place. The confusing part is that the bottom pin looks stepped. Like you wouldn’t be able to punch it out from one side. i’ve attached pictures. Thanks.

I see that there is one pin for the top of each cylinder so that one looks like it must be pulled out.

Top pins you just thread a bolt in em and yank out. You have to take off one of the clamp brackets on side to remove lower pin.

thanks for the info! does it matter which clamp bracket I remove? I see there is a woodruff key in the pin based on the schematic. Just wondering if the bottom key will come out either way, or needs to come out one side only?
