2.8  THE SADDLE PLATE: 
 
2.8.1  Dismantling the saddle plate: 
 
Undo the two M10 bolts and remove the so-called "locking spanner", which is fastened 
to the bottom strip of the saddle plate.  
Use this spanner to undo the two locking nuts. 
Undo the two M10 bolts and remove the two shafts. 
Now the saddle plate can be removed without any problems. 
 
2.8.2  Assembling the saddle plate: 
 
Assemble the saddle plate in the reverse order to which you dismantled it. 
 
2.9  THE CYLINDER: 
 
Removing the cylinder: 
 
Place the grab bucket in the closed position and make sure it is stable.  
Unscrew the nuts at each end of the cylinder. 
Pull in the piston rod with the aid of oil pressure and make sure when doing so that the 
cylinder ends are protected from damage. 
Once this has been done, the cylinder can be removed in its entirety. 
 
Dismantling the cylinder: 
 
Unscrew and remove the head bush. 
When the head bush is removed, carefully remove the piston rod. 
 
Caution!  Take care not to damage the piston rod. 
 
To replace the seals, you must first remove the outer cylinder tube. 
The non-return valve can be removed and mounted at all times without any problems, 
providing there is no pressure on the cylinder. 
 
Reassembling the cylinder: 
 
Assemble the cylinder parts in the reverse order to which you dismantled them. 
 
N.B.: 

When mounting the head bush, you must use Loctite type 243 or a  

 

comparable locking agent.
