Service and conversion work
springs on the diaphragm plate must be
aligned centrally between two bolting
holes in the diaphragm (see Fig.9-2).
7. Place the hose clamp (A6) evenly into the
groove in the diaphragm (A4) intended
for it.
8. 240cm²: turn the screw on the latch of
the hose clamp until the hose clamp rests
completely in the groove. Tighten the
screw of the latch using a suitable tool.
Observe tightening torques.
350 and 700cm²: turn the screw on the
latch of the hose clamp until only a gap
of just a few millimeters remains between
the diaphragm (A4) and hose clamp
(A6).
Place and align the compressor (A19)
beneath the clamp's latch (see Fig.9-2).
Tighten the screw of the latch using a
suitable tool. Observe tightening torques.
9. Apply a suitable lubricant to the actuator
stem (A7).
10. Clamp the top diaphragm case (A1) with
the opening facing upward into a suit-
able clamping xture.
11. Place the diaphragm plate assembly con-
sisting of the diaphragm plate (A5), new
diaphragm (A4) and actuator stem (A7)
with the actuator stem pointing upward
into the diaphragm case (A1).
12. Place the springs (A10) in the diaphragm
plate (A5), centering them in the intend-
ed recesses.
13. Carefully guide the bottom diaphragm
case (A2) over the actuator stem (A7)
and place it on the springs (A10). Make
sure that the sealing elements are not
damaged. Ensure that the compressed
air connections on the cases (A1, A2)
are correctly aligned with each other.
14. Fasten the top and bottom diaphragm
cases (A1, A2) together using the nuts
(A21) and bolts (A20). Observe tighten-
ing torques.
