ROD SET DISASSEMBLY

Hold the rod assembly in a vice using a D18mm half-shell (tighten
sufficiently so that the rod does not turn on itself when unscrewing
the nut)

Heat the nut for a few moments
It is recommended to clamp the rod flush with the damper
foot. This will prevent damage to the rod in the effective
working area if the vice is not tight enough.

After heating the nut, loosen it with a ratchet and a 19 mm socket
If you have a Factory-R shock absorber, heat the stop
piston holder at the base and unscrew it with a 19 mm
open-end wrench

Position a valve or screwdriver at the end of the rod and slide the piston assembly over it

Clean the valve assembly and the piston. Use a clean cloth and some degreaser. Dry the parts well
afterwards.
- When cleaning, place all the parts in the order of disassembly on a clean cloth on your
workbench to ensure proper reassembly.
- A wrong order of assembly of the valves will induce a bad functioning of your damper.

Cut the guide band of the main piston with a blade. Remove it
and the O-ring under it.

Position the seal and the new guide band on your piston
