STEM FOLDING HINGE
HOW TO GREASE THE FOLDING HINGE
In general there is no maintenance needed.
But after frequent use or after heavy rain we
recommend to clean the folding hinge and to
apply some viscous oil.
HOW TO DISMANTLE THE FOLDING HINGE
The folding hinge should be dismantled only
by an expert.
• Open the lever and remove left and right
bolt M 4x10.
• Loosen both bolts M 4x16.
• Push the eccentric to the right side until you
can see the grub screw at the right side.
Loosen the grub screw.
• Remove bolt from the eccentric.
• Clean all parts with a dry cloth.
HOW TO ASSEMBLE THE FOLDING HINGE
• Grease inside of shell and the areas of
eccentric and bolt which touch the folding
hinge. Grease the cone and the washers.
• Place the washers on the folding hinge
plates (use some grease to hold them on).
• Place the cone and the tension rod
together with the shell into the folding
hinge plate.
• Push the eccentric through washer, folding
hinge plate and shell.
• Push the bolt onto the eccentric and as-
sembly the right bolt M 4x10. Tighten the
grub screw. Take care that the grub screw
hits the flat section of the eccentric.
• Put the lever onto the eccentric. As-
semble cap and left bolt M 4x10. Do not
tighten the bolts.
• Adjust clamping force, action point and
axial play. Take care of correct tightening of
all bolts.
ATTENTION!
Now the stem is loose and can
fall down! Watch out for the thin
washers.
