SUPER HYDROBAR HS
Define pusher lenght

Insert a pusher into the spindle and push it
until it is 10mm short of the lathe collet.

Make a mark at 190mm, measuring from the
lathe spindle (T).

Using a punch (51/C), extract (51/1) the pin
(51/G).

Separate (51/2) the pusher from the piston .

Saw the pusher at the point you marked. Re-
drill the hole for the pin using the previous
measurements.

Snagg all holes well and reassemble the
pusher. When reinserting the pin, make sure
that it does not stand proud of the pusher
otherwise the guide tube will be damaged.
When assembled, the piston must be free
and must not be pressing against the pusher.
Replace the pusher in the HS and check that
in the end-of-bar position it does not touch
the lathe collet.
Do the same with the other pushers.

When at the end-of-bar position, the pusher
is still 40mm inside the tube.
By adding the 150mm distance between the
leading end of the tube and the spindle (see
point 2.2.2., FIG.33), you get the 190mm
mentioned above.
or lathes whose spindle is set
back (52/R) more than 50mm
inside the casing, it is necessary
to consider cutting away the
housing (52/T), see even
installing a retraction system.
Pushers less than 13 mm:
Pushers of diameter less than 13 mm, cannot be separated from the piston and must therefore be cut at
the front. After having shortened them, refashion a conical chamfer on the end of the pushers, identical to
that which has been cut off.
For pushers fitted with rotating ferrules, see next pages
