Did an air spring service on my Recon Gold last week and lost track of which o-ring I removed from the bottom of the negative air piston.
There are two o-rings in the service kit of the same diameter but different thickness that would fit but if I install the thinner of the two it seems like the piston doesn't seal - very high pressures and the forks are still soft, although randomly they'll stiffen up especially if I cycle them quickly a few times in succession.
If I install the thicker of the two I can't seem to get the piston to fit back into the uppers. The other piston definitely takes a thicker o-ring but also has a wider o-ring groove so isn't as difficult to insert.
Picture for reference - A is the thinner o-ring, B is the thicker, the third marker shows the location on the piston.
Apologies for the lack of dimensions - I'll run the calipers over everything later on if needed.
