Repair and Re-assembly. See figure 3-89.
Remove hydraulic cylinder from the installation. Disconnect hose lines and cap hose ports to prevent both loss of
oil and contamination from entering the system. Drain the oil from the cylinder.
Clean complete exterior of cylinder of all loose dirt and oil.
Using suitable face spanner wrench remove the cylinder head. If the cylinder head does not turn easily do not
force it causing damage. The exterior of the cylinder tube may have to be heated around the thread area to free
the cylinder head.
Withdraw the cylinder shaft with piston from the tube.
