Dismantling the steering cylinder
On the steering cylinder, it can be very difficult to remove the pis-
ton from the cylinder as the O ring in the cylinder head sticks in
the locking ring groove of the cylinder pipe. It is best, therefore, to
first remove the O ring before attempting to draw out the piston
rod from the cylinder.
1. Unscrew the end piece at the cylinder head.
2. Unscrew the connection nipple for the hydraulic hose.
3. Push in the piston rod with piston head until the O ring is visi-
ble through the nipple hole.
4. Use a strong, bent steel wire to hook onto the O ring, illustra-
tion A.
5. Draw up the O ring a little and get a grip on the O ring with a
pair of thin nosed pliers, illustration B.
6. Continue and draw out the O ring through the hole.
7. Maintain a grip on the O ring and cut through it with a knife.
8. Rotate the piston rod and simultaneously draw out the O ring
through the hole, illustration C.
9. Remove the locking ring from the cylinder pipe.
10.Carefully draw out the piston rod from the cylinder pipe.
