The cylinder (part no. 33249) 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. 1)
from the cylinder tube (pos. 2). A special tool must be used to remove the
cap. If the cap is stuck, it may help to warm up the front of the 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. 2).
3.
The seal in the cap (pos. 1) as well as the sleeve are removed.
4.
All parts are cleaned and checked for chips, burrs etc. Check for rust
around the scraper ring in the cap (pos. 1). If this is the case, remove it.
Mounting
1.
New seals are mounted in the cap (pos. 1) and the piston.
2.
The thread on the cap (pos. 1) and the cylinder tube (pos. 2) are lubricated
with oil or grease.
3.
The cap (pos. 1) is mounted on the piston rod.
4.
The piston is mounted and the locking nut is screwed on 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 piston 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 (pos. 1) is installed on the cylinder tube (pos. 2) and tightened.
