NOTE!
Indicates information that is of importance re-
garding mounting procedures.
MOUNTING INSTRUCTION
12.
Check that the steering stops work as they
should. The damper should not act as a steering
stop since that can damage and possibly break
the steering damper.
13.
First loosen the top nut and then the slit screw.
Tighten them again, first the top nut to 10 Nm
and then the slit screw to 30 Nm (higher than
recommended).
14.
Tighten all screws for the triple clamps to
recommended tightening torque.
15.
Tighten the top nut again to 20 Nm.
16.
Install every removed part in reverse order.
17.
Finally install the centre lid by pressing it into
the hex opening. Use a M6 screw and a pair of
pliers if you must remove the lid. Note! Do not try
to remove the lid with a screwdriver - the lid will
break!
Your installation is finished - Enjoy your Öhlins
product!
Reset the adjusters according to following:
The adjusters have a normal right hand thread.
Turn the damping adjusters clockwise to fully
closed (pos. zero [0]). To open, turn counter
clockwise, and count the clicks until you reach
the recommended number. For more information read your Öhlins Owner’s
manual.

MOUNTING INSTRUCTION MOUNTING INSTRUCTION
WARNING!
It is advisable to have an Öhlins dealer install the
steering damper.
1.
Secure your vehicle and remove the front wheel,
front fork and triple clamps. Refer to your vehicle
service manual. Also remove the original upper
steering stem nut and washer (you will not need
those when using Öhlins steering damper).
2.
Remove the outer ring of the upper steering
head bearing. Refer to your vehicles manual -
changing steering bearing.
3.
Replace the outer ring with the bracket provided.
The bracket is press fitted into the steering head.
It is of critical importance that the bracket is
mounted straight. It is possible to correct the
position by tapping it with a hammer after the
bracket is mounted.
4.
Apply some grease on the x-ring and install it (do
not twist it) in to the groove on the seal washer.
Grease and install the upper bearing and the
seal washer provided (the provided seal washer
replaces the original dust seal, if any). The flat
side of the seal washer should face upwards
according to figure.
5.
Mount the tower in the bracket with the provided
nut. Depending on the offset place the tower
according to figure 5b. If you are unsure which
offset you have - see your vehicles service manual.
If needed, use washers between the tower and the
bracket to achieve the correct distance between the
top of the tower and the lever - see figure 5. Tighten
the nut to the tower with 25 Nm. Use loctite 270.
NOTE!
For some models the threads of the tower can interfere
with the frame. If necessary grind the threads until it
fits. The tower should just touch the seal according to
figure.
6.
Use grease inside the tower to avoid the noise that
otherwise can occur.
7.
Mount the triple clamps and fork legs.
8.
Mount the steering damper. As with the bracket
it is of critical importance that the damper is
mounted centered and straight according to
figure. Since the two small pins will be pressed
down into the upper triple clamp when the upper
steering stem nut provided is tightened, it is
important to make sure the damper sits straight
before tightening. If the damper is not aligned
properly after the pins have been pressed down
into the triple clamp, it may be necessary to remove
the bracket that holds those two pins that sits
underneath the damping housing. There are two
extra holes there so the position of the pins can
be changed. The pins are (loosely) press fitted into
the bracket and can easily be removed and then
mounted again.
9.
Tighten the screws for the upper triple clamp.
10.
Tighten the slit screw to 30 Nm.
11.
Again make sure that the damper sits straight and
then then tighten the upper steering stem nut to
70-80 Nm. This will press down the pins into the
triple clamp.
