Compression valve servicing

Disassembly

Clamp the compression valve (43) at the flat faces in a vice. Be careful not to
damage the washers and do not overtighten.
Loosen the screw (36) using a 12 mm wrench.
Remove in the order: screw (36), spring (37), by-pass washer (38), piston (39)
with its O-ring (40), compression washer or washer stack (41).

Assembly

Washers (41) and piston (39) control compression damping.
When needed, the fork's compression response may be tuned by choosing
washers (41) and a piston (39) with different specifications. The by-pass
washer (38) is necessary for suspension operation but plays not role in
the setting procedure. Never replace this washer (38) with another part
with different specifications.
WARNING
Use only genuine Marzocchi washers and pistons. Do not make changes
to fork components.
Replace the piston O-ring (40) if needed.
Install the compression washer or washer stack (41) and the piston (39) with its
O-ring (40) on the compression valve.
Slide the spring (37) and the by-pass washer (38) over the screw (36).
Hold the spring compressed and tighten the screw (36) onto the compression
valve (43). Make sure to tighten the screw fully home into its seat and check that
the washer moves freely through its full stroke.
WARNING
The piston (39) has a mounting position (shown in the figure). Its cylindrical
section must be facing away from the compression washers.
Tighten the screw (36) finger tight.
Clamp the compression valve (43) in a vice being careful not to overtighten.
Tighten the screw (36) to the specified torque using a 12 mm wrench (see Tight-
ening Torque Figures table).
