Write the assembly side of the piston (5). The beveled part 
"A" of the piston is oriented towards the head (2). 

FIGURE 14: 

Remove all seals, anti-extrusion rings and scra-

per rings from head (2), cylinder (3) and piston (5).

 NOTE:

1 - All seals must be replaced every time the unit is disas-
sembled. 

2 - Particular attention must be paid not to damage the
