MORDAZAS DE ALTA PRESION
C. INSTRUCTIONS FOR DISASSEMBLING THE SPINDLE FROM THE VICE
1. Dismantle the movable jaw as explained in item B (cleaning) above.
2. Loosen the 2 end clamp screws and the 2 allen set screws (2004) on the head of the vice.
Remove the whole assembly "spindle and spindle shoe". The end clamp should come out
easily.
3. The hydraulic unit (threaded spindle) must be detached from the pneumatic cylinder unit. To
ease dismantling of the two parts it has two flats at the coupling. Unscrew the screw (004) –
on size 090 it is (014)-, holding up the threaded spindle unscrew the pneumatic cylinder unit.
E
Remove the spindle shoe carefully ensuring that the "protecting spiral" does not "open"
completely.
D. HYDRAULIC OIL REPLENISHING
1. Dismantle as shown in "C" above until the hydraulic unit is free.
2. Unscrew the allen set screw (215) – size 090 does not have this allen set screw- and cap
(1606) from the cylinder-holder (1601), do not mislay spring (605) – on size 090 it is (1605)-
and washer (1621).
3. Replace seal (1622) into the cylinder-holder (1601) with the sealing lips towards bottom and
seal (1623) in the lodgement formed by parts (1602 & 1603) also with the sealing lips towards
bottom.
4. Introduce fixed cylinder (1602) and seal guide (1603) threaded between themselves forming
one piece, into the cylinder-holder (1601) matching the holes of both parts.
5. Fit allen set screw (2004) in their lodgements and with an air line pressurise to enable the seal
(1622) –on size 090 it is (009)- to self-fit into its correct position.
6. With allen set screws (2004), push parts (1602 and 1603) until the end of cylinder-holder (1601).
7. Carefully pour hydraulic oil through the central hole of part (1603) until the level reaches the
top, checking that the oil chamber is completely free of air bubbles. If required, stir with a clean
wooden toothpick or similar and refill as required again to the top.
8. Carefully, without taking out the allen set screws, replace gently seal (410) –on size 090 it is
(1605)- into small piston (1607) and introduce it into guide (1603) .
9. Replace spring (605), washer (1621) and threaded spindle (1608) and screw the cap (1606).
Screw this cap with a key (DIN 1804) until it reaches the end. Replace screw (215) – size 090
does not have this allen-set-screw.
Note : Oil replenishing can be made without replacing effective seals, but it may be considered
that new seals can be fitted as programmed maintenance.
E. FINAL SETTING AND REGULATING
When an oil refilling and/or a seal replacement has been completed, check carefully that the
operation has been successful, before fitting the spindle to the vice.
1. Assemble the pneumatic cylinder to the end of the threaded spindle (1608).
2. Hold the assembly –by the threaded spindle- in the horizontal position and introduce the allen
set screw (2004) into the hole of the fixed cylinder (1602).
3. As air pressure is now introduced into the pneumatic cylinder, it will be apparent if the operation
has been completed successfully. Operate open-close a few times successfully before using
the vice in production. If the vice action is incorrect, retrace the dismantle/assemble instructions
until the vice action is normal.
