Compression Valve Overhauling - Husqvarna 2009 TE 310 Workshop Manual

COMPRESSION VALVE OVERHAULING

Dismantling
• Being very careful not to damage the washers, clamp the compression valve (43)
into the vice, exploiting the parallel surfaces and without over-tightening.
• With a 12 mm spanner, unscrew nut (36).
• In sequence, remove the nut (36), the spring (37), the by-pass washer (38), the
piston (39) with O-ring (40) and the washer or washers' stack which regulate
compression (41).
Assembly
Washers (41) and piston (39) are responsible for the compression braking.
Replacing washers (41) and piston (39) with other partswith different
characteristics, lets you change the fork behaviour during compression if
needed. The by-pass washers (38) are responsible for rebound braking.
Whenever necessary, fork behaviour can be modified during compression by
replacing the washers (38) with others having different features
WARNING
Use only Marzocchi original washers and pistons. Do not modify the
components.
• Replace the piston O-ring (40) if necessary.
• Install the washer or washers' stack which regulate compression (41) and the
piston (39) with O-ring (40) onto the bottom valve.
• Insert the spring (36) and the by-pass washer (37) into nut (38).
• Keeping the spring compressed, tighten the screw (36) onto the compression valve
(43) being very careful that it goes right into its housing and the washer is free to run
its course.
WARNING
The piston (39) must be positioned as shown in the diagramso that the
cylindrical part is opposite the washers which regulate compression.
• Tighten the screw (36) by hand.
• Clamp the compression valve (43) in the vice without tightening.
• With a 12mm spanner, tighten the screw (36) to the required torque (see Table 5
- Tightening torques).
