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. 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 towards the
bearing.
5.
Mount the tower in the bracket. 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.
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. Tighten the tower with 25
Nm.
6.
Use grease inside the tower to avoid the noise
that otherwise can occur.
7.
Mount the triple clamps and fork legs. Tighten the
bolts on the lower triple clamp to recommended
tightening torque.
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.
Again make sure that the damper sits straight
and then tighten the upper steering stem nut to
correct torque according to your vehicles Owners
manual. Note! All threads on the upper steering
stem nut will not be used, that is correct as long
as the nut is tightened properly.
