4. Slide the piston into centre position, where after the top piece (pos. 8) is
unscrewed approx. 25 mm. A special tool is needed to remove the top
piece. If the top piece is very tight, a minor heating of the socket's front
part will loosen it. When the top piece has been unscrewed 25 mm, the
piston can be pulled out towards the top piece and then the top piece can
be screwed off entirely, where after the piston rod (pos. 6) can be pulled
out of the cylinder tube (pos. 5).
5. Remove the locking nut at the bottom of the piston rod.
6. Pull the sleeve shoe (pos. 2) off the piston rod.
7. Pull the top piece (pos. 8) off the piston rod.
8. Remove the packings in the top piece and the sleeve shoe (pos.
1+3+4+7+9+10+11).
9. Clean all parts and check for cuttings, burrs etc. Check for any rust gath-
erings around the scraber ring (pos. 11) in the top piece. If any rust is
found it must be removed.

Mounting

1. Mount the new packings in the top piece and the sleeve shoe.
2. Apply grease or rust-preventive anti-seizure agent to the thread of the top
piece (pos. 8) and the cylinder tube.
3. Mount the top piece (pos. 8) on the piston rod.
4. Mount the sleeve shoe (pos. 2) and then screw on the locking nut and
lock it with Loctite. Make sure that the thread is completely clean and
free of oil and dirt before using Loctite. After using Loctite do not fill
with oil before 12 hours hereafter.
5. Lubricate the sleeve of the sleeve shoe (pos. 2) as well as the inside of the
cylinder tube with oil and then slide the piston into a middle position.
6. Screw on the top piece and tighten it.
7. Mount the cylinder. Use self-tightening nuts and avoid tightening the nuts
too hard. The cylinder eye must be able to turn around freely in the fork.
8. Mount the tubes. Make sure that the tubes are not exposed to any squeez-
ing and that the connections are tight.
