1.
The cylinder is emptied of oil by carefully moving the piston back and forth.
2. Move the piston to the middle position, then unscrew the end cap (pos. 3)
from the cylinder tube (pos. 1). A special tool must be used to remove the
cap. If the cap is really stuck, it may help to warm up the front of the upper
cap. When the cap is unscrewed from the cylinder tube, pull the piston
towards the cap. The piston rod can then be removed from the cylinder
tube (pos. 1).
3. The lock nut (pos. 10) that is holding the sleeve (pos. 4) is disassembled.
4. The sleeve (pos. 4) is removed from the piston rod (pos. 2).
5. The cap (pos. 3) is pulled off the piston rod (pos. 2).
6. The seals in the cap (pos. 5+6+7+8+9) as well as the sleeve are removed.
7. All parts are checked for chips, burrs etc. Check for rust around the scraper
ring (pos. 5) in the cap. If this is the case remove it.
Mounting
1.
New seals (pos. 5+6+7+8+9) are fitted in the cap and sleeve.
2. The thread on the cap (pos. 3) and the cylinder tube (pos. 1) are lubricated
with oil.
3. The cap (pos. 3) is mounted on the piston rod.
4. The sleeve (pos. 4) is installed and the lock nut is screwed and secured
with Loctite. Make sure the thread is absolutely clean and free of oil and
other impurities before using Loctite. Do not fill with oil within 12 hours
of using Loctite.
5. Lubricate the outermost seal on the sleeve that comes in contact with the
cylinder tube and the cylinder tube internally with oil and push the piston
into the middle position.
6. The cap is installed on the cylinder tube and tightened.
7. To mount the cylinder, refer to “Changing the tilt cylinder”.
