The flat slide 3 and the slide plate 4 should always
be removed together.

5 and the new flat slide, the gap
"S" > 0.8, (wear at the drive pin) the drive pin must also be replaced.
The drive pin is supplied by us ready to be fitted with pre-stressed piston rings.
It must not be dismantled.
REPAIR OF THE STUFFING
When replacing the stuffing, pay
attention to the position and the
layering of the top packings and
spring washers.
All the stuffings should be
replaced as complete units.
– The top packings cannot be
replaced individually.
If the running surfaces of the step
piston show palpable signs of
wear (scoring, pitting), it must
also be replaced.
