Ohlins FG 670 - Manual (Page 12)

Assembly of the forks
1.
Use Tool 786-07 to refit the reservoir tube.
Tighten to 45 Nm.
2.
Use Tool 786-05 to refit the inner tube of
the fork leg. Tighten to 80 Nm.
3.
Put the outer tube standing up on a soft
surface, seal side up. Fit the bushings
from the seal side of the outer leg. Install
first the upper bushing then the lower one.
Use installing sleeve (1759-08), guide ring
(1758-04) and attachment bar (1757-01)
when installing the upper bushing. Ap-
ply Loctite 601 on the seat position of the
upper bushing, use a long brush. Tap the
attachment bar until it reaches the correct
position (stop against a shoulder).
4.
When the upper bushing is in position, the
lower bushing is to be installed the same
way. Apply some red grease (146-01) to
the bushing before installation.
5.
Apply a thin layer of Öhlins red grease
(146-01) to the washer and to the sealing
surfaces of the fork seal. Install the seal
and the washer in the outer tube. Fit the
circlip into the groove.
NOTE!
It is important to use the correct grease in
order to achieve optimum fork function.
6.
Install the piston and the shims on the
base valves. Tighten the 8 mm nut with
a torque of 7 Nm. Check the piston ring
and the O-rings for damages. Replace if
necessary.
Install the base valve assembly into the
valve housing. Tighten to 20 Nm.
