The bushings are exchangeable. For that pur-
pose you will have to dismount the rear swing
arm and send it together with the axle via
your specialist dealer to HP V
ELOTECHNIK.After
having been mounted the bushings are machi-
ned to adjust them.
Undoing the axle screws
In order to mount the rear rack or the lowri-
der the axle screws have to be undone.We re-
commend you to leave one screw in place to
prevent the axle from turning.
In case the rear swing arm is to be dismoun-
ted completely you can prevent the axle from
turning by inserting a thin metal rod in the ho-
le of the axle through the drilling of the rear
swing arm under the axle.
Swing arm pivot
Swing arm pivot
The rear swing arm pivot comes with mainte-
nance free bushings.They have a self lubricating
system with Teflon particles.The bushings
sustain a very high load and they show almost
no wear.
In case you notice play or a creaking noise at
the rear swing arm please check the two
screws that keep the axle in the frame.They
will have to be secured with L
OCTITE.
Tightening torques:
Mushroom head screw M8x25 (without rear
rack): 14-16 Nm
Screw M8x45: 17-19 Nm
Danger! If the screws at the axle are not
tight enough this leads to play and noises
when the spring compresses. In extreme ca-
ses the swing arm may come loose which le-
ads to a serious fall. If the screws are too
tight the thread of the axle may tear out or
the screw may be damaged.
Caution! There has to be a big washer bet-
ween the main frame and the end of the
bushing else the busing is not able to func-
tion without play and the frame will be da-
maged.
You can prevent the axle from turning by inserting a thin metal
rod in the hole of the axle.
