Secure the spring by tightening the adjustment
ring until the spring doesn't show any play any
more. If there is a safety spring ring, push it
back into the slot on the thread.
Move the rear swing arm back up and connect
the rear end of the suspension element with
the rear swing arm using the bolt. Lubricate
the bolt thoroughly.
Secure the screws of the suspension element
with threadlocker and tighten the screws with
6-8 Nm.
After having exchanged the spring you have to
readjust the spring preload as described in the
chapter on "Adjusting your new bicycle" on
page 18.
Cleaning and lubricating
Do clean the suspension element, especially
the polished piston rod, if it is dirty. Remaining
dirt and sand can damage the seals of the hy-
draulic system and so shorten its life consider-
ably.We recommend you to protect the su-
spension element from dirt with an elastic co-
ver that you can buy at your local dealer when
riding on dirty roads regularly.
From time to time grease the thread for the
spring pre-load with a drop of acid-free oil.
Thus, you can always turn the adjustment ring
easily by hand. Once a year you have to grease
the pivots of the suspension element. For that
purpose dismount the suspension element as
described under "Changing the Spring" on
page
42
.
Remove the plastic spacers and pull the metal
tube out off the bushing. Lubricate the bushing
and the tubes with grease. Finally remount the
suspension element.
Hydraulic dampers are affected by wear and
tear through normal use. It depends on the
usage of the trike, the amount of dirt on it and
the maintenance and lubrication.After 3000
km the damper must receive an inspection by
a trained mechanic, worn out parts or the hy-
draulic cartridge can be replaced then. Due to
wear of the seals oil can leak from the damper.
The internal oil can become foamy.This may
lead to some noise when the damper is wor-
king.This noise does not effect the function of
the damper. Only if there is no obvious dam-
ping after the first 5 mm of travel, the damper
should be replaced.
Please also note the maintenance instructions
of the damper manufacturer provided with
your trike.
The bushings of the rear spring element need to be lubricated
once a year.
