Remove the rear support 1, the rear seal 2 and the

the cylinders all around with a plastic hammer helps to
loosen them from possible scaling or deposit
accumulated during operation.
Insert a pin of adequate dimensions and smartly tap
until the complete pressure packing set is out (Fig. 25).
Replace pressure packing set at every inspection.
Remove the upper cover (1, Fig. 20).
Once the cylinders are removed, loosen the plungers and
check them for wear (Fig 22). Replace if necessary.
