Caution!
For models with Teflon overlays (30), position the overlay between the outer diaphragm plate (5) and the
diaphragm (3) before attaching the inner diaphragm plate (5).
9. Screw stud (35) into the end of the diaphragm rod, place washer (47) onto stud (35) and bumper (3) onto
diaphragm rod. Screw the diaphragm assembly to one end of the diaphragm rod and tighten to 0 ft-lbs (3.56
Nm). Position the outer chamber (8) and lightly tighten fasteners (6, 7, 8, 33).
Insert a pry bar into the chamber`s suction opening until it touches the hex boss of the outer diaphragm plate
(5). Move the diaphragm rod toward the open chamber. Wedge a block of wood between the pry bar and the
side of the suction opening to hold the diaphragm rod in position.
Invert the second diaphragm assembly, place washer (47) onto stud (35) and bumper (3) onto diaphragm rod.
Screw the diaphragm assembly to the end of the diaphragm rod, and tighten to 0 ft-lbs (3.56 Nm) of torque.
Roll the outside bead of the diaphragm toward the outer chamber. Position the outer chamber (8) and tighten
fasteners (6, 7, 8, 33) to 0 ft-lbs (7. Nm) of torque. Return to the first outer chamber, align the suction
opening flanges until they are level and on the same plane, tighten fasteners (6, 7, 8, 33) to 0 ft-lbs (7.
Nm) of torque.
0. Place the check balls (7) and check valve seats (6) in the discharge manifold (), position on the outer
chamber (8) and reassemble using fasteners (6, 7, 8). Place the check balls (7) and check valve seats
(6) in the outer chambers (8), position the suction manifold (3) and reasssemble using fasteners (6, 7,
8). Torque all manifold fasteners to 50 Nm.
0a. For models using Teflon elastomers, check valve seats (5), and o-rings (4), make sure that the o-rings (4)
are facing the machined flanges of the suction manifold (3) and/or discharge manifold (). Also make sure
that the o-rings do not shift from their grooves during reassembly.
3.10.3 External Fastener Torque Requirements
Caution!
When reassembling, loosely tighten all external fasteners adjusting and aligning and gradually, in an alternat-
ing fashion, tighten to torque requirements listed below.
Diapraghm Plates 7 Nm
Diaphragm/Rod 3.5 Nm
Chambers 7 Nm
Manifolds/Chamber 50 Nm
Air Valve Body 4.5 Nm
