cylinder. Partially remove the bolt until the lower end of the cylinder is free. Keep the shoulder
spacer/sleeve (I). Disengage the lower end of the cylinder from the remaining sleeve.
7. Using an 11/16" wrench, loosen the lock nut (J) and unscrew the cylinder completely from the end
fitting (K). Note the location of the lock nut before loosening it so the new cylinder will be properly
screwed into the end fitting.
8. Reverse the above steps to install the new cylinder.
