Put the washer on the sheetmetal bracket at
the handlebar stem and the rod end on top of
it. Insert the bolt and tighten the self-locking
nut.
On the other side of the track rod the rod
end is mounted on the underside of the
knuckle. Note:There is an additional spacer
between washer and rod end.
Adjusting toe-in
The front wheels are held by knuckles which
can turn at the ends of the main frame.The
knuckles are connected by tie rods to the
handlebar stem.
The rod ends consist of ball-and-socket bear-
ings that can be screwed in or out of the tie-
rod for length adjustment.
Length adjustment is done at the inner tie-rod
end, at the connection to the handlebar stem.
The outer rod-end is screwed completely into
the rod and secured with threadlocker. Do not
try to turn this side of the rod end.
First make sure that the handlebar is aligned
perpendicular to the main frame tube. Identify
which wheel (or perhaps both wheels) needs
adjustments of the toe-in by measuring the
distance between rim wall and main tube on
the most forward point and on the most back-
ward point of the rim (value a
v
and a
h
in the
picture).The distances should be roughly iden-
tical for one wheel.
Remove the bolt that connects the inner rod-
end to the handlebar stem, note the washer.
Hold the rod-end with a wrench and loosen
the nut that is screwed against the rod-end.
Screw the rod-end into the tie-rod to enlarge
the distance b
v
between the front edges of the
front wheel. Screw the rod-end out of the tie-
rod to decrease the distance of the front
wheel edges.Attach the tie-rod to the handle-
bar stem and measure the toe-in as described
above. Repeat the adjustment process until
you reach the required toe-in setting.
Align both rod-ends parallel to each other.
Grip the rod-end with a wrench and tighten
the nut against the tie-rod with 4–5 Nm.
Danger!
The rod-end must be screwed at
least 8 mm into the tie-rod. If it is screwed
out to far, the thread could tear out and the
trike could become unsteerable.This means
that with a standard length of the thread of
the rod-end of 24 mm, a maximum of 11
mm visible free thread length is allowed bet-
ween rod-end and lock-nut.The lock nut
must be screwed tight to the tie-rod, other-
wise the rod-end could loosen up or play
could develop.
Caution!
Do not move the rod-end beyond
its limits, or it will be destroyed or get ex-
cessive play.Always hold the rod end with a
wrench or secure the tie rod with a wrench
against turning when tightening the lock nut.
Caution!
Make sure the washer is between
rod end and bracket to allow the full mova-
bility of the rod end.
