Each tube is filled, to a step made in the inside, with special oil, and the piston (made up earlier) shoved in, with excess oil wiped away.
I'll be honest, I'm not convinced by all this. I did it twice to ensure that the dampers ended up as two identical pairs, but with no experience, how much damping should they do?
I've done a little research, and these are considered old-fashioned, so long term I might find out what the current state of the art is, and replace them.
As usual, everything bolts into place perfectly. Another tip I read while digging around, was to mount the dampers upside down, to stop the oil dripping out. Does this make sense (I ask, because I know there are people with experience of this sort of thing reading these words)? If I'm wrong, swapping them over won't take very long at least.
You've done the right thing in mounting the dampers upside down Phil, it's a recognised mod on these kits where tolerances aren't as tight as they could be. If mounted the right way up and the model is left standing for a period of time any imperfections in the seals will allow the shock oil to slowly leak out leaving you with a puddle on your shelf (or where ever it is standing) and a much reduced damping effect to the suspension. The viscosity of the shock oil being forced past/through the piston is what gives the damping effect, without the oil there is minimal damping.
