Plain dampening rod in hand
brass bushing w/circlip keeper
top out spring
washer/spring valve, wavy spring towards the bottom
aluminum spacer
long aluminum bushing, deep hollow side down
Press the aluminum bushing, with the appropriate hammer & socket combo, into
the fork leg. You can freeze the aluminum bushing if you want to make it
easier to press in. It's not a difficult press, but it is snug. You are
assembling this as a unit so don't send the dampening rod out the other end
of the bushing or you will have to start again. Don't forget the circlip
that goes in the bottom of the fork leg to keep this whole assembly in the
forks.
