Caution!
If air valve has been removed, proper orientation of air system with fluid chambers must be observed. The
bottom of the intermediate has the smaller hook shaped air passage slot on the air valve mounting face and
the outer chamber check ball cavity should be pointing downward.
9. Replace all external fasteners and tighten to final torque requirement after pump is completely assembled.
0. Position the manifolds making sure of the proper orientation in relation to the air valve for your application.
Also make sure that the manifold o-rings do not shift from their grooves during reassembly. Tighten all external
fasteners to final torque requirement after pump is completely assembled.
3.7.3 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.
Air valve cap screws 4.5 Nm
Manifold bolts .3-.5 Nm
Outer chamber cap screws 8.5-9.5 Nm
Caution!
Always torque the chamber bolts prior to the manifold bolts.
3.7.4 Maintenance of Air Valve
. To evaluate air valve components, remove the four cap screws (), washers, (5, 0) and nuts (7) from the
air valve body (7). The shuttle plate (5) and shuttle (6) may be inspected by removing them from their location in
the slot in the back of the air valve. Inspect for scratches or surface irregularities. Replace if necessary. Remove
the plug () at the bottom of the air valve. Next push the air valve spool () out of the air valve body. Gently reach
in and pull lip seals (43) out of inside bore of the air valve body. Check for cracks, splitting or scratches. Clean
components if replacement is not necessary. Inspect plug o-ring (44) for any damage and replace if necessary
and reinsert in o-ring groove.
Caution!
Make sure that the open sides of the two lip seals (43) face each other when reassembling air valve. Lube all
components with suggested maintenance grease as an aid in reassembly.
. Reinsert air valve spool () inside of air valve body (7). Place shuttle (6) on middle rib of air valve spool ()
through the square slot in back of air valve (7). Lubricate side of plate (5) that faces the shuttle (6) and reposition
valve plate over shuttle. Press the valve plug () into air valve body, chamfered end first.
3. Check that gasket (4) is not cracked. If damaged replace.
4. After gasket (4) is pressed back into position align air valve onto intermediate and reinsert the four cap screws
() with lock washer (5) and flat washers (0). Apply 4.5 Nm of torque to fasteners.
