Reattach the foam tube that covers the large
rod ends and a short part of the oval wish-
bone tube. Mount the rod ends to the frame
brackets.
To finish the front axle setup measure and ad-
just the toe as described in "Front wheel align-
ment" on page 39.

To measure the front wheel's camber angle
position a long square next to the wheel coni-
cident with the wheel axis. Set the lower dis-
tance between rim wall and square to 40 mm
(s
u
= 40 mm).The upper measure s
o
between
rim wall and square should be 36 mm (+0,5°
positive camber) now and must be in a range
of 32 (+1° positive camber) to 48 mm (-1°
negative camber).The difference between the
measure s
o
on the left and right wheel must
not exceed 4mm.
For adjusting works, the trike should be
mounted in a workstand, best upside down.
The stabilizer bar must be disassembled.
To adjust the front axle both rod ends of one
wishbone must be disassembled from the
frame. Loosen the counter nuts and screw in
or out the rod ends according to the table on
the left.Values in between can be interpolated.
Check the values after provisionally reattach-
ing the wishbone and wheel on a plane floor.
Repeat the adjustment if necessary.
After having reached the correct setup, fasten
the counter nuts of the rod ends with 4–5
Nm.
