Servicing

Disassembly is fairly straight forward. The only slightly painful part of the process is the need to make a special tool to remove the air spring and damper unit from the stanchions. The ends of the damper unit and air spring have a recessed hexagonal interface. I drilled out a suitable sized nut and then used a spanner on the nut to undo. Note! The damper and air spring units are reversed threaded into the stanchions, so turn clockwise to undo.
