9. Tilt the barrel and the bushing will fall out into your hand. If you are not replacing the
seal, skip steps 10-12.
10. Push the interior shaft back down in to the barrel until the seal falls out through the other
end of the barrel. As the seal comes out of the barrel, make a note of its orientation, so
you will know how to put it back in. Replace the seal, if necessary.
11. Insert the flared end of the seal into the end of the barrel.
