5-11. Replacing the Pusher Y Cylinder (Outer Shape Reference)
1) Detach the par d or e from
the cylinder c.
2) Loosen the nut (accessory) of
the cylinder c to detach it from
the part f.
3) Loosen the nut h(accessory)
to detach the pusher B g from
the top of the cylinder c.
4) Reassemble the components in the reverse
order of steps 1) to 3). When installing a
new pusher Y cylinder, check and adjust as
described below.
c Adjust so that the distance B is 1.5 mm
± 0.1mm when the Y pusher is ON
(extruded) and distance A is -0.5 mm ±
0.1mm when the Y pusher is OFF (not
extruded).
(See Figure 5-11-2.)
d
djust so that the gap C between the Y
pusher and transport belt is 0.2 mm
minimum.

After the cylinder components have been assembled, supply the air (0.5 MPa) to check that
the cylinder moves smoothly.
e Adjust so that the pressure reducing valve is 0.5 MPa and the speed controller is opened
two turns from the fully closed position.
